TITLE
BIR domains of mammalian IAP gene family
This is a divisional application of
Canadian Patent Application Serial No. 2,228,635 filed on
August 5, 1996.
TECHNICAL FIELD OF THE INVENTION
The invention relates to apoptosis. The subject
matter of this divisional application is directed to the BIR
domains and variants of the mammalian IAP gene family. The
application is also drawn to nucleic acids encoding the BIR
domains and their variants, as well as uses of the BIR
domains and their variants.
It should be understood that the expression "the
invention" and the like encompass the subject matter of both
the parent and this divisional application.
BACKGROUND OF THE INVENTION
There are two general ways by which cells die.
The most easily recognized way is by necrosis, which is
usually caused by an injury that is severe enough to disrupt
cellular homeostasis. Typically, the cell's osmotic
pressure is disturbed and, consequently, the cell swells and
then ruptures. When the cellular contents are spilled into
the surrounding tissue space, an inflammatory response often
ensues.
The second general way by which cells die is
referred to as apoptosis, or programmed cell death.

la
Apoptosis often occurs so rapidly that is difficult to
detect. This may help to explain why the involvement of
apoptosis in a wide spectrum of biological processes has
only recently been recognized.
The apoptosis pathway has been highly conserved
throughout evolution, and plays a critical role in embryonic
development, viral pathogenesis, cancer, autoimmune
disorders, and neurodegenerative disease. For example,
inappropriate apoptosis may cause or contribute to AIDS,
Alzheimer's Disease, Parkinson's Disease, Amyotrophic
Lateral Sclerosis (ALS), retinitis pigmentosa and other
diseases of the retina, myelodysplastic syndrome (e. g.
aplastic anemia), toxin-induced liver disease, including
alcoholism, and ischemic injury (e. g. myocardial infarction,
stroke, and reperfusion injury). Conversely, the failure of
an apoptotic response has been implicated in the development
of cancer, particularly follicular lymphoma, p53-mediated
carcinomas, and hormone-dependent tumours, in autoimmune
disorders, such as lupus erythematosis and multiple
CA 02403947 2002-10-21
-2-
sclerosis, and in viral infections, including those
associated with herpes virus, poxvirus, arid adenovirus.
In patients infected with HIV-1, mature CD4+
T lymphocytes respond to stimulation from mitogens or
s super-antigens by undergoing apoptosis. However, the
great majority of these cells are not infected with the
virus. Thus, inappropriate antigen-induced apoptosis
could be responsible for the destruction of this vital
part of the immune system in the early stages of HIV
to infection.
Baculoviruses encode proteins that are termed
inhibitors of apoptosis proteins (IAPs) because they
inhibit the apoptosis that would otherwise occur when
insect cells are infected by the virus. These proteins
is are thought to work in a manner that is independent of
other viral proteins. The baculovirus IAP genes include
sequences encoding a ring zinc finger-like motif (RZF),
which is presumed to be directly involved in DNA binding,
and two N-terminal domains that consist of a 70 amino
zo acid repeat motif termed a BIR domain (Baculovirus IAP
Repeat).
Summary of the Invention
In general, the invention features a substantially
pure DNA molecule, such as a genomic, cDNA, or synthetic
is DNA molecule, that encodes a mammalian IAP polypeptide.
This DNA may be incorporated into a vector, into a cell,
which may be a mammalian, yeast, or bacterial cell, or
into a transgenic animal or embryo thereof. In preferred
embodiments, the DNA molecule is a murine gene (e.g., m-
3o xiap, m-hiap-1, or m-hiap-2) or a human gene (e. g., xiap,
hiap-1, or hiap-2). In most preferred embodiments the
IAP gene is a human IAP gene. In other various preferred
embodiments, the cell is a transformed cell. In related
aspects, the invention features a transgenic animal

d

containing a transgene that encodes an IAP polypeptide
that is expressed in or delivered to tissue normally
susceptible to apoptosis, i.e., to a tissue that may be
harmed by either the induction or repression of
s apoptosis. In yet another aspect, the invention features
DNA encoding fragments of IAP polypeptides including the
BIR domains and the RZF domains provided herein. -
In specific embodiments, the invention features
DNA sequences substantially identical to the DNA
to sequences shown in Figs. 1-6, or fragments thereof. In
another aspect, the invention also features RNA which is
encoded by the DNA described herein. Preferably, the RNA
is mRNA. In another embodiment the RNA is antisense RNA.
In another aspect, the invention features a
t5 substantially pure polypeptide having a sequence
substantially identical to one of the IAP amino acid
sequences shown in Figures 1-6.
In a second aspect, the invention features a
substantially pure DNA which includes a promoter capable
Zo of expressing the IAP gene in a cell susceptible to
apoptosis. In preferred embodiments, the IAP gene is
xiap, hiap-1, or hiap-2. Most preferably, the genes are
human or mouse genes. The gene encoding hiap-2 may be
the full-length gene, as shown in Fig. 3, or a truncated
2s variant, such as a variant having a deletion of the
sequence boxed in Fig. 3.
In preferred embodiments, the promoter is the
promoter native to an IAP gene. Additionally,
transcriptional and translational regulatory regions are,
so preferably, those native to an IAP gene. In another
aspect, the invention provides transgenic cell lines and
transgenic animals. The transgenic cells of the
invention are preferably cells that are altered in their
apoptotic response. In preferred embodiments, the
35 transgenic cell is a fibroblast, neuronal cell, a
CA 02403947 2002-10-21
-4-
lymphocyte cell, a filial cell, an embryonic stem cell, or
an insect cell. Most preferably, the neuron is a motor
neuron and the lymphocyte is a CD4+ T cell.
In another aspect, the invention features a method
s of inhibiting apoptosis that involves producing a
transgenic cell having a transgene encoding an IAP
polypeptide. The transgene is integrated into the genome
of the cell in a way that allows for expression.
Furthermore, the level of expression in the cell is
~o sufficient to inhibit apoptosis.
In a related aspect, the invention features a
transgenic animal, preferably a mammal, more preferably a
rodent, and most preferably a mouse, having either
increased copies of at least one IAP gene inserted into
~s the genome (mutant or wild-type), or a knockout of at
least one IAP gene in the genome. The transgenic animals
will express either an increased or a decreased amount of
IAP polypeptide, depending on the construct used and the
nature of the genomic alteration. For example, utilizing
Zo a nucleic acid molecule that encodes all or part of an
IAP to engineer a knockout mutation in an IA_D gene would
generate an animal with decreased expression of either
all or part of the corresponding IAP polypeptide. In
contrast, inserting exogenous copies of all or part of an
is IAP gene into the genome, preferably under the control of
active regulatory and promoter elements, would lead to
increased expression or the corresponding IAP
polypeptide.
In another aspect, the invention features a method
30 of detecting an IAP gene in a cell by contacting the IAP
gene, or a portion thereof (which is greater than 9
nucleotides, and preferably greater than 18 nucleotides
in length), with a preparation of genomic DNA from the
cell. The IAP gene and the genomic DNA are brought into
ss contact under conditions that allow for hybridization

that are at least 50% identical to the DNA encoding HIAP-
1, HIAP-2, or XIAP polypeptides.
In another aspect, the invention features a method
s of producing an IAP polypeptide. This method involves
providing a cell with DNA encoding all or part of an IAP
polypeptide (which is positioned for expression in the
cell), culturing the cell under conditions that allow for
expression of the DNA, and isolating the IAP polypeptide.

expressed by DNA that is under the control of a
constitutive or inducible promotor. As described,~herein,
the promotor may be a heteroiogous promotor.
In another aspect, the invention features

zo HIAP-1, HIAP-2, M-XIAP, M-HIAP-1, or M-HIAP-2
polypeptide. Fragments including one or more BIR._domains
(to the exclusion of the RZF), the RZF domain (to the
exclusion of the BIR domains), and a RZF domain with at
least one BIR domain, as provided herein, are also. a part
zs of the invention.
In another aspect, the invention features a
recombinant mammalian polypeptide that is capable of
modulating apoptosis. The polypeptide may include at
least a ring zinc finger domain and a BIR domain as

3s chain reaction, for example, the RACE method. In another
CA 02403947 2002-10-21
7
aspect, the invention features an IAP gene isolated
according to the method involving: (a) providing a
preparation of DNA; (b) providing a detectably labelled
DNA sequence having homology to a conserved region of an
s IAP gene; (c) contacting the preparation of DNA with the

providing a cell sample; (b) introducing by
transformation into the cell sample a candidate IAP gene;
(c) expressing the candidate IAP gene within the cell
is sample; and (d) determining whether the cell sample
exhibits an altered apoptotic response, whereby a
response identifies an IAP gene.
In another aspect, the invention features a

to (a) providing a preparation of cellular DNA (for example,
from the human genome or a cDNA library (such as a cDNA
library isolated from a cell type which undergoes
apoptosis); (b) providing a detectably-labelled DNA

35 (b) contacting the library with a detectably-labelled
CA 02403947 2002-10-21
gene fragment produced according to the PCR method of the
invention under hybridization conditions providing
detection of genes having 50% or greater nucleotide
sequence identity; and (c) isolating an IAP gene by its
s association with the detectable label. In another
aspect, the invention features a method of identifying an
IAP gene involving: (a) providing a cell tissue sample;
(b) introducing by transformation into the cell sample a
candidate IAP gene; (c) expressing the candidate IAP gene
io within the cell sample; and (d) determining whether the
cell sample exhibits inhibition of apoptosis, whereby a
change in (i.e. modulation of) apoptosis identifies an
IAP gene. Preferably, the cell sample is a cell type
that may be assayed for apoptosis (e.g., T cells, B
~5 cells, neuronal cells, baculovirus-infected insect cells,
glial cells, embryonic stem cells, and fibroblasts). The
candidate IAP gene is obtained, for example, from a-cDNA
expression library, and the response assayed is the
inhibition of apoptosis.
zo In another aspect, the invention features a
method of inhibiting apoptosis in a mammal wherein the
method includes: (a) providing DNA encoding at least one
IAP polypeptide to a cell that is susceptible to
apoptosis; wherein the DNA is integrated into the genome
zs of the cell and is positioned for expression in the cell;
and the IAP gene is under the control of regulatory
sequences suitable for controlled expression of the
gene(s); wherein the IAP transgene is expressed at a
level sufficient to inhibit apoptosis relative to a cell
30 lacking the IAP transgene. The DNA integrated into the
genome may encode all or part of an IAP polypeptide. It
may, for example, encode a ring zinc finger and one or
more BIR domains. In contrast, it may encode either the
ring zinc finger alone, or one or more BIR domains alone.
35 Skilled artisans will appreciate that IAP polypeptides

may also be administered directly to inhibit undesirable
apoptosis.
In a related aspect, the invention features a
method of inhibiting apoptosis by producing a cell that
s has integrated, into its genome, a transgene that
includes the IAP gene, or a fragment thereof. The IAP
gene may be placed under the control of a promoter
providing constitutive expression of the IAP gene.
Alternatively, the IAP transgene may be placed under the
~o control of a promoter that allows expression of the gene
to be regulated by environmental stimuli. For example,
the IAP gene may be expressed using a tissue-specific or
cell type-specific promoter, or by a promoter that is
activated by the introduction of an external signal or
~s agent, such as a chemical signal or agent. In preferred
embodiments the cell is a lymphocyte, a neuronal cell, a
glial cell, or a fibroblast. In other embodiments, the
cell in an HIV-infected human, or in a mammal suffering
from a neurodegenerative disease, an ischemic injury, a
zo toxin-induced liver disease, or a myelodysplastic
syndrome.
In a related aspect, the invention provides a

In another aspect, the invention features a
purified antibody that binds specifically to an IAP
family protein. Such an antibody may be used in any
3o standard immunodetection method for the identification of
an IAP polypeptide. Preferably, the antibody binds
specifically to XIAP, HIAP-1, or HIAP-2. In various
embodiments, the antibody may react with other IAP

35 polypeptides. The antibody may be a monoclonal or a
CA 02403947 2002-10-21

- 10 -
polyclonal antibody. Preferably, the antibody reacts
specifically with only one of the IAP polypeptides, for
example, reacts with murine and human xiap, but not with
hiap-1 or hiap-2 from other mammalian species.
According to a further aspect of the present
invention, there is provided a substantially pure mammalian
IAP polypeptide, or fragment thereof that specifically binds
an antisera directed to an IAP.
The antibodies of the invention may be prepared by
a variety of methods. For example, the IAP polypeptide, or
antigenic fragments thereof, can be administered to an
animal in order to induce the production of polyclonal
antibodies. Alternatively, antibodies used as described
herein may be monoclonal antibodies, which are prepared
using hybridoma technology (see, e.g., Kohler et al., Nature
256:495, 1975; Kohler et al., Eur. J. Immunol. 6:511, 1976;
Kohler et al., Eur. J. Immunol. 6:292, 1976; Hammerling
et al., In Monoclonal Antibodies and T Cell Hybridomas,
Elsevier, NY, 1981). The invention features antibodies that
specifically bind human or murine IAP polypeptides, or
fragments thereof. In particular the invention features
"neutralizing" antibodies. By "neutralizing" antibodies is
meant antibodies that interfere with any of the biological
activities of IAP polypeptides, particularly the ability of
IAPs to inhibit apoptosis. The neutralizing antibody may
reduce the ability of IAP polypeptides to inhibit
polypeptides by, preferably 50&, more preferably by 70~, and
most preferably by 90~ or more. Any standard assay of
apoptosis, including those described herein, may be used to
assess neutralizing antibodies.

In addition to intact monoclonal and polyclonal
anti-IAP antibodies, the invention features various
genetically engineered antibodies, humanized antibodies, and
antibody fragments, including F(ab')2, Fab', Fab, Fv and sFv
fragments. Antibodies can be humanized by methods known in

Alto, CA). Fully human antibodies, such as those
expressed in transgenic animals, are also features of the
invention (Green et al., Nature Genetics 7:13-21, 1994).

s describes methods for preparing single polypeptide chain
,antibodies. Ward et al. (Nature 341:544-546, 1989)
describe the preparation of heavy chain variable domains,
which they term "single domain antibodies," which have
high antigen-binding affinities. McCafferty et al.
to (Nature 348:552-554, 1990) show that complete antibody V
domains can be displayed on the surface of fd
bacteriophage, that the phage bind specifically to
antigen, and that rare phage (one in a million) can be
isolated after affinity chromatography. Boss et al.
~5 (U.S. Patent 4,816,397) describe various methods for
producing immunoglobulines, and immunologically
functional fragments thereof, which include at least the
variable domains of the heavy and light chain in a single
host cell. Cabilly et al. (U. S. Patent 4,816,567)
zo describe methods for preparing chimeric antibodies.
In another aspect, the invention features a
method of identifying a compound that modulates
apoptosis. The method includes providing a cell
expressing an IAP polypeptide, contacting the cell with a
z5 candidate compound, and monitoring the expression of an
IAP gene. An alteration in the level of expression of
the IAP gene indicates the presence of a compound which
modulates apoptosis. The compound may be an inhibitor or
an enhancer of apoptosis. In various preferred
~o embodiments, the cell is a fibroblast, a neuronal cell, a
glial cell, a lymphocyte (T cell or B cell), or an insect
cell; the polypeptide expression being monitored is XIAP,
HIAP-1, HIAP-2, M-XIAP, M-HIAP-1, or M-HIAP-2 (i.e.,
human or murine).

In a related aspect, the invention features
methods of detecting compounds that modulate apoptosis
using the interaction trap technology and IAP
polypeptides, or fragments thereof, as a component of the
s bait. In preferred embodiments, the compound being
,tested as a modulator of apoptosis is also a polypeptide.
In another aspect, the invention features a
method for diagnosing a cell proliferation disease, or an
increased likelihood of such a disease, using an IAP
~o nucleic acid probe or antibody. Preferably, the disease
is a cancer. Most preferably, the disease is selected
from the group consisting of promyelocytic leukemia, a
HeLa-type carcinoma, chronic myelogenous leukemia
(preferably using xiap or hiap-2 related probes),
~5 lymphoblastic leukemia (preferably using a xiap related
probe), Burkitt's lymphoma (preferably using an hiap-1
related probe), colorectal adenocarcinoma, lung
carcinoma, and melanoma (preferably using a xiap probe).
Preferably, a diagnosis is indicated by a 2-fold increase
zo in expression or activity, more preferably, at least a
10-fold increase in expression or activity.
Skilled artisans will recognize that a mammalian
IAP, or a fragment thereof (as described herein), may
serve as an active ingredient in a therapeutic
2s composition. This composition, depending on the IAP or
fragment included, may be used to modulate apoptosis and
thereby treat any condition that is caused by a
disturbance in apoptosis.
In addition, apoptosis may be induced in a cell
3o by administering to the cell a negative regulator of the
IAP-dependent anti-apoptotic pathway. The negative
regulator may be, but is not limited to, an IAP
polypeptide that includes a ring zinc finger, and an IAP
polypeptide that includes a ring zinc finger and lacks at
35 least one BIR domain. Alternatively, apoptosis may be
CA 02403947 2004-08-16
76962-52D(S)
13
induced in the cell by administering a gene encoding an IAP
polypeptide, such as these two polypeptides. In yet another
method, the negative regulator may be a purified antibody,
or a fragment thereof, that binds specifically to an IAP
polypeptide. For example, the antibody may bind to an
approximately 26 kDa cleavage product of an IAP polypeptide
that includes at least one BIR domain but lacks a ring zinc
finger domain. The negative regulator may also be an IAP
antisense mRNA molecule.

finger domains from the human or murine xiap, hiap-1 and
hiap-2). Representative members of the IAP gene family
include, without limitation, the human and murine xiap,
s hiap-l, and hiap-2 genes.
By "IAP protein" or "IAP polypeptide" is meant a
polypeptide, or fragment thereof, encoded by an IAP gene.

~s Xaal-Pro-Xaal-Cys-Xaal-Phe-Val, wherein Xaal is any amino
acid and Xaa2 is any amino acid or is absent (SEQ ID

identical to one of the BIR domain sequences provided for
xiap, hiap-1, hiap-2 herein.

wherein Xaal is any amino acid, Xaa2 is Glu or Asp, and
Xaa3 is Val or Ile (SEQ ID NO:1).
Preferably, the sequence is substantially
identical to the RZF domains provided herein for the
3o human or murine xiap, hiap-1, or hiap-2.
By "modulating apoptosis" or "altering
apoptosis" is meant increasing or decreasing the number
of cells that would otherwise undergo apoptosis in a
given cell population. Preferably, the cell population
3s is selected from a group including T cells, neuronal

a
- t5 -
cells, fibroblasts, or any other cell line known to
undergo apoptosis in a laboratory setting (e.g., the
baculovirus infected insect cells). It will be
appreciated that the degree of modulation provided by an
s IAP or modulating compound in a given assay will vary,
but that one skilled in the art can determine the
statistically significant change in the level of
apoptosis which identifies an IAP or a compound which
modulates an IAP.
to By "inhibiting apoptosis" is meant any decrease
in the number of cells which undergo apoptosis relative
to an untreated control. Preferably, the decrease is at
least 25%, more preferably the decrease is 50%, and most
preferably the decrease is at least one-fold.
is By "polypeptide" is meant any chain of more than
two amino acids, regardless of post-translational
modification such as glycosylation or phosphorylation.
By "substantially identical" is meant a
polypeptide or nucleic acid exhibiting at least 50%,
zo preferably 85%, more preferably 900, and most preferably
95% homology to a reference amino acid or nucleic acid
sequence. For polypeptides, the length of comparison
sequences will generally be at least 16 amino acids,
preferably at least 20 amino acids, more preferably at
is least 25 amino acids, and most preferably 35 amino acids.
For nucleic acids, the length of comparison sequences
will generally be at least 50 nucleotides, preferably at
least 60 nucleotides, more preferably at least 75
nucleotides, and most preferably 110 nucleotides.
3o Sequence identity is typically measured using
sequence analysis software with the default parameters
specified therein (e. g., Sequence Analysis Software
Package of the Genetics Computer Group, University of
Wisconsin Biotechnology Center, 1710 University Avenue,
3s Madison, WI 53705). This software program matches
CA 02403947 2002-10-21
d

similar sequences by assigning degrees of homology to
various substitutions, deletions, and other
modifications. Conservative substitutions typically
include substitutions within the following groups:
s glycine, alanine, valine, isoleucine, leucine; aspartic
acid, glutamic acid, asparagine, glutamine; serine,
threonine; lysine, arginine; and phenylalanine, tyrosine.
By "substantially pure polypeptide" is meant a
polypeptide that has been separated from the components
~o that naturally accompany it. Typically, the polypeptide
is substantially pure when it is at least 60%, by weight,
free from the proteins and naturally-occurring organic
molecules with which it is naturally associated.
Preferably, the polypeptide is an IAP polypeptide that is
~s at least 75%, more preferably at least 90%, and most
preferably at least 99%, by weight, pure. A
substantially pure IAP polypeptide may be obtained, for
example, by extraction from a natural source (e.g. a
fibroblast, neuronal cell, or lymphocyte) by expression
zo of a recombinant nucleic acid encoding an IAP
polypeptide, or by chemically synthesizing the protein.
Purity can be measured by any appropriate method, e.g.,
by column chromatography, polyacrylamide gel
electrophoresis, or HPLC analysis.
zs A protein is substantially free of naturally
associated components when it is separated from those
contaminants which accompany it in its natural state.
Thus, a protein which is chemically synthesized or
produced in acellular system different from the cell from
so which it naturally originates will be substantially free
from its naturally associated components. Accordingly,
substantially pure polypeptides include those derived
from eukaryotic organisms but synthesized in E. coli or
other prokaryotes. By "substantially pure DNA" is meant
35 DNA that is free of the genes which, in the naturally-

occurring genome of the organism from which the DNA of
the invention is derived, flank the gene. The term
therefore includes, for example, a recombinant DNA which
is incorporated into a vector; into an autonomously
s replicating plasmid or virus; or into the genomic DNA of
a prokaryote or eukaryote; or which exists as a separate
molecule (e. g., a cDNA or a genomic or cDNA fragment
produced by PCR or restriction endonuclease digestion)
independent of other sequences. It also includes a
1o recombinant DNA which is part of a hybrid gene encoding
additional polypeptide sequence.
By "transforated cell" is meant a cell into which
(or,into an ancestor of which) has been introduced, by
means of recombinant DNA techniques, a DNA molecule
1s encoding (as used herein) an IAP polypeptide.
By "transgene" is meant any piece of DNA which
is inserted by artifice into a cell, and becomes part of
the genome of the organism which develops from that cell.
Such a transgene may include a gene which is partly or
zo entirely heterologous (i.e., foreign) to the transgenic
organism, or may represent a gene homologous to an
endogenous gene of the organism.
By "transgenic" is meant any cell which includes
a DNA sequence which is inserted by artifice into a cell
is and becomes part of the genome of the organism which
develops from that cell. As used herein, the transgenic
organisms are generally transgenic mammalian (e. g.,
rodents such as rats or mice) and the DNA (transgene) is
inserted by artifice into the nuclear genome.
so By "transformation" is meant any method for
introducing foreign molecules into a cell. Lipofection,
calcium phosphate precipitation, retroviral delivery,
electroporation, and biolistic transformation are just a
few of the teachings which may be used. For example,
3s biolistic transformation is a method for introducing
CA 02403947 2002-10-21
t
18
foreign molecules into a cell using velocity driven
microprojectiles such as tungsten or gold particles.
Such velocity-driven methods originate from pressure
bursts which include, but are not limited to, helium-
s driven, air-driven, and gunpowder-driven techniques.
.Biolistic transformation may be applied to the
transformation or transfection of a wide variety of cell
types and intact tissues including, without limitation,
intracellular organelles (e.g., and mitochondria and
~o chloroplasts), bacteria, yeast, fungi, algae, animal
tissue, and cultured cells.
By "positioned for expression" is meant that the
DNA molecule is positioned adjacent to a DNA sequence
which directs transcription and translation of the
~s sequence (i.e., facilitates the production of, e.g., an
IAP polypeptide, a recombinant protein or a RNA
molecule).
By "reporter gene" is meant a gene whose
expression may be assayed; such genes include, without
zo limitation, glucuronidase (GUS), luciferase,
chloramphenicol transacetylase (CAT), and p-
galactosidase.
By "promoter" is meant minimal sequence
sufficient to direct transcription. Also included in the
zs invention are those promoter elements which are
sufficient to render promoter-dependent gene expression
controllable for cell type-specific, tissue-specific or
inducible by external signals or agents; such elements
may be located in the 5' or 3' regions of the native
3o gene .
By "operably linked" is meant that a gene and
one or more regulatory sequences are connected in such a
way as to permit gene expression when the appropriate
molecules (e.g., transcriptional activator proteins are
35 bound to the regulatory sequences).
CA 02403947 2002-10-21

By "conserved region" is meant any stretch of
six or more contiguous amino acids exhibiting at least
30%, preferably 50%, and most preferably 70% amino acid
sequence identity between two or more of the IAP family
s members, (e. g., between human HIAP-1, HIAP-2, and XIAP).
.Examples of preferred conserved regions are shown (as
boxed or designated sequences) in Figures 5-7 and Tables
1 and 2, and include, without limitation, BIR domains and
ring zinc finger domains.
~o By "detectably-labelled" is meant any means for
marking and identifying the presence of a molecule, e.g.,
an oligonucleotide probe or primer, a gene or fragment
thereof, or a cDNA molecule. Methods for detectably-
labelling a molecule are well known in the art and
~s include, without limitation, radioactive labelling (e. g.,
with an isotope such as 32P or 35S) and nonradioactive
labelling (e. g., chemiluminescent labelling, e.g.,
fluorescein labelling).
By "antisense," as used herein in reference to
Zo nucleic acids, is meant a nucleic acid sequence,
regardless of length, that is complementary to the coding
strand of a gene.
By "purified antibody" is meant antibody which
is at least 60%, by weight, free from proteins and
zs naturallyoccurring organic molecules with which it is
naturally associated. Preferably, the preparation is at
least 75%, more preferably 90%, and most preferably at
least 99%, by weight, antibody, e.g., an IAP specific
antibody. A purified antibody may be obtained, for
so example, by affinity chromatography using recombinantly-
produced protein or conserved motif peptides and standard

Detailed Description
I. IAP Genes and Polypeptides
A new class of mammalian proteins that modulate
3o apoptosis (IAPS) and the genes that encode these proteins
have been discovered. The IAP proteins are characterized
by the presence of a ring zinc finger domain (RZF; Fig.
9) and at least one BIR domain, as defined by the boxed
consensus sequences shown in Figs. 7 and 8, and by the
CA 02403947 2002-10-21

r
sequence domains listed in Tables 1 and 2. As examples
of novel IAP genes and proteins, the cDNA sequences and
amino acid sequences for human IAPs (HIAP-1, HIAP-2, and
XIAP) and a new murine inhibitor of apoptosis, XIAP, are
s provided. Additional members of the mammalian IAP family
.(including homologs from other species and mutant
sequences) may be isolated using standard cloning
techniques and the conserved amino acid sequences,
primers, and probes provided herein and known in the art.
~o Furthermore, IAPs include those proteins lacking the ring
zinc finger, as further described below.

Recognition of the mammalian IAP family has
provided an emergent pattern of protein structure.
Recognition of this pattern allows proteins having a
known, homologous sequence but unknown function to be
is classified as putative inhibitors of apoptosis. A
drosophila gene, now termed diap, was classified in this
way (for sequence information see Genbank Accession
Number M96581 and Fig. 6). The conservation of these
proteins across species indicates that the apoptosis
zo signalling pathway has been conserved throughout
evolution.
The IAP proteins may be used to inhibit the
apoptosis that occurs as part of numerous disease
processes or disorders. For example, IAP polypeptides or
zs nucleic acid encoding IAP polypeptides may be
administered for the treatment or prevention of apoptosis
that occurs as a part of AIDS, neurodegenerative
diseases, ischemic.injury, toxin-induced liver disease
and myelodysplastic syndromes. Nucleic acid encoding the
3o IAP polypeptide may also be provided to inhibit
apoptosis.

II. Cloning of IAP Genes
A. xiap
The search for human genes involved in apoptosis
resulted in the identification of an X-linked sequence
s tag site (STS) in the GenBank database, which
demonstrated strong homology with the conserved RZF
domain of CpIAP and OpIAP, the two baculovirus genes
known to inhibit apoptosis (Clem et al., Mol. Cell Biol.
14:5212-5222, 1994; Birnbaum et al., J. Virol. 68:2521-8,
~0 1994). Screening a human fetal brain ZapII cDNA library
(Stratagene, La Jolla, CA) with this STS resulted in the
identification and cloning of xiap (for X-linked
Inhibitor of Apoptosis Protein gene). The human gene has
a 1.5 kb coding sequence that includes three BIR domains
~5 (Crook et al., J. Virol. 67:2168-74, 1993; Clem et al.,
Science 254:1388-90, 1991; Birnbaum et al., J. Virol.,
68:2521-8, 1994) and a zinc finger. Northern blot
analysis with xiap revealed message greater than 7 kb,
which is expressed in various tissues, particularly liver
Zo and kidney (Fig. 12). The large size of the transcript
reflects large 5' and 3' untranslated regions.
B. Human hiap-1 and hiap-2
The hiap-1 and hiap-2 genes were cloned by
screening a human liver library (Stratagene Inc.,
z5 LaJolla, CA) with a probe including the entire xiap
coding region at low stringency (the final wash was
performed at 40°C with 2X SSC, 10% SDS; Figs. 2 and 3).
The hiap-1 and hiap-2 genes were also detected
independently using a probe derived from an expressed
3o sequence tag (EST; GenBank Accession No. T96284), which
includes a portion of a BIR domain. The EST sequence was
originally isolated by the polymerase chain reaction; a
cDNA library was used as a template and amplified with
EST-specific primers. The DNA ampliderived probe was
35 then used to screen the human liver cDNA library for
CA 02403947 2002-10-21
- 26 -
full-length hiap coding sequences. A third DNA was
subsequently detected that includes the hiap-2 sequence
but that appears to lack one exon, presumably due to
alternative m.RNA splicing (see boxed region in Fig. 3).
s The expression of hiap-1 and hiap-2 in human tissues as
assayed by Northern blot analysis is shown in Figures 8
and 9.
C. m-xiap
Fourteen cDNA and two genomic clones were
~o identified by screening a mouse embryo .lgtll cDNA library
(Clontech, Palo Alto, CA) and a mouse FIX II genomic
library with a xiap cDNA probe, respectively. A cDNA
contig spanning 8.0 kb was constructed using 12
overlapping mouse clones. Sequence analysis revealed a
is coding sequence of approximately 1.5 kb. The mouse gene,
m-xiap, encodes a polypeptide with striking homology to
human XIAP at and around the initiation methionine, the
stop codon, the three BIR domains, and the RZF domain.
As with the human gene, the mouse homologue contains
Zo large 5' and 3' UTRs, which could produce a transcript as
large as 7-8 kb.
Analysis of the sequence and restriction map of
m=xiap further delineate the structure and genomic
organization of m-xiap. Southern blot analysis and
zs inverse PCR techniques (Groden et al., Cell 66:589-600,
1991) can be employed to map exons and define exon-intron
boundaries.
Antisera can be raised against a m-xiap fusion
protein that was obtained from, for example, E. coli
3o using a bacterial expression system. The resulting
antisera can be used along with Northern blot analysis to
analyze the spatial and temporal expression of m-xiap in
the mouse.
CA 02403947 2002-10-21

D. m-hiap-1 aid m-hian-2
The murine homologs of hiap-1 and hiap-2 were
cloned and sequenced in the same general manner as m-xiap
using the human hlap-1 and hiap-2 sequences as probes.
s Cloning of m-hiap-1 and m-hiap-2 further demonstrate that
.homologs from different species may be isolated using the
techniques provided herein and those generally known to
artisans skilled in molecular biology.
III. Identification of Additional IAP Genes
~o Standard techniques, such as the polymerase
chain reaction (PCR) and DNA hybridization, may be used
to clone additional human IAP genes and their homologues
in other species. Southern blots of human genomic DNA
hybridized at low stringency with probes specific for
~s xiap, hiap-1 and hiap-2 reveal bands that correspond to
other known human IAP sequences as well as additional
bands that do not correspond to known IAP sequences.
Thus, additional IAP sequences may be readily identified
using low stringency hybridization. Examples of murine
zo and human xiap, hiap-1, and hiap-2 specific primers,
which may be used to clone additional genes by RT-PCR,
are shown in Table 5.
IV. Characterization of IAP Activity
and Intracellular Localization Studies
zs The ability of putative IAPs to modulate
apoptosis can be defined in in vitro systems in which
alterations of apoptosis can be detected. Mammalian
expression constructs carrying IAP cDNAs, which are
either full-length or truncated, can be introduced into
3o cell lines such as CHO, NIH 3T3, HL6~, Rat-1, or Jurkat
cells. In addition, SF21 insect cells may be used, in
which case the IAP gene is preferentially expressed using
an insect heat shock promotor. Following transfection,
apoptosis can be induced by standard methods, which
35 include serum withdrawal, or application of
staurosporine, menadione (which induces apoptosis via
CA 02403947 2004-08-16
76962-52D (S)
_ zs _
free radial formation), or anti-Fas antibodies. As a
control, cells are cultured under the same conditions as
those induced to undergo apoptosis, but either not
transfected, or transfected with a vector that lacks an
s IAP insert. The ability of each IAP construct to inhibit
,apoptosis upon expression can be quantified by
calculating the survival index of the cells, i.e., the
ratio of surviving transfected cells to surviving control
cells. These experiments can confirm the presence of
~o apoptosis inhibiting activity and, as discussed below,
can also be used to determine the functional regions) of
an IAP. These assays may also be performed in
combination with the application of additional compounds
in order to identify compounds that modulate apoptosis
~s via IAP expression.
A. Cell Survival followinct Transfection
with Full-length IAP Constructs
and Induction of Apoptosis
Specific examples of the results obtained by
zo performing various apoptosis suppression assays are shown
in Figs. 14A to 14D. For example, CHO cell survival.
following transfection with one of six constructs and
subsequent serum withdrawal is shown in Fig. 14A. The
cells were transfected using Lipofectace" with 2 ~g of
z5 one of the following recombinant plasmids: pCDNA36myc-
xiap (xiap), pCDNA3-6myc-hiap-1 (hiap-1), pCDNA3-6myc-
hiap-2 (hiap-2), pCDNA3-bcl-2 (bcl-2), pCDNA3-HA-smn
(smn), and pCDNA3-6myc (6-myc). Oligonucleotide primers
were synthesized to allow PCR amplification and cloning
30 of the xiap, hiap-1, and hiap-2 ORFs in pCDNA3
(Invitrogen). Each construct was modified to incorporate
a synthetic myc: tag encoding six repeats of the peptide
sequence MEQKLISEEDL [(SEQ ID N0:43)], thus allowing
detection of myc-IAP fusion proteins via monoclonal anti-
3s myc antiserum (Egan et al., Nature 363:45-51, 1993).
Triplicate samples of cell lines in 24-well dishes were
CA 02403947 2002-10-21
washed 5 times with serum free media and maintained in
serum free conditions during the course of the
experiment. Cells that excluded trypan blue, and that
were therefore viable, were counted with a hemocytometer
s immediately, 24 hours, 48 hours, and 72 hours, after
.serum withdrawal. Survival was calculated as a
percentage of the initial number of viable cells. In
this experiment and those presented in Figs. 14B and 14D,
the percentage of viable cells shown represents the
to average of three separate experiments performed in
triplicate, +/- average deviation.
The survival of CHO cells following transfection
(with each one of the six constructs described above) and
exposure to menadione is shown in Fig. 14B. The cells
~s were plated in 24-well dishes, allowed to grow overnight,
and then exposed to 20 ~.M menadione for 1.5 hours (Sigma
Chemical Co., St. Louis, MO). Triplicate samples were
harvested at the time of exposure to menadione and 24
hours afterward, and survival was assessed by trypan blue
zo exclusion.
The survival of Rat-1 cells following
transfection (with each one of the six constructs
described above) and exposure to staurosporine is shown
in Fig. 14C. Rat-1 cells were transfected and then
zs selected in medium containing 800 ~tg/ml 6418 for two
weeks. The cell line was assessed for resistance to
staurosporine-induced apoptosis (1 ~cM) for 5 hours.
Viable cells were counted 24 hours after exposure to
staurosporine by trypan blue exclusion. The percentage
30 of viable cells shown represents the average of two
experiments, ~ average deviation.
The Rat-1 cell line was also used to test the
resistance of these cells to menadione (Fig. 14D)
following transfection with each of the six constructs
3s described above. The cells were exposed to 10 ~.M

menadione for 1.5 hours, and the number of viable cells
was counted 18 hours later.
B. Comparison of Cell Survival
Followinct Transfection with
Full-length vs. Partial IAP Constructs
In order to investigate the mechanism whereby
'human IAPs, including XIAP, HIAP-1, and HIAP-2, afford
protection against cell death, expression vectors were
constructed that contained either: (1) full-length IAP
i0 cDNA (as described above), (2) a portion of an IAP gene
that encodes the BIR domains, but not the RZF, or (3) a
portion of an IAP gene that encodes the RZF, but not the
BIR domains. Human and murine xiap or m-xiap cDNAs were
tested by transient or stable expression in HeLa, Jurkat,
~5 and CHO cell lines. Following transfection, apoptosis
was induced by serum withdrawal, application of
menadione, or application of an anti-Fas antibody. Cell
death was then assessed, as described above, by trypan
blue exclusion. As a control for transfection
Zo efficiency, the cells were co-transfected with a ~-gal
expression construct. Typically, approximately 20% of
the cells were successfully transfected.
When CHO cells were transiently transfected,
constructs containing full-length xiap or m-xiap cDNAs
zs conferred modest protection against cell death
(Fig. 15A). In contrast, the survival of CHO cells
transfected with constructs encoding only the BIR domains
(i.e., lacking the RZF domain; see Fig. 15A) was markedly
enhanced 72 hours after serum deprivation. Furthermore,
3o a large percentage of cells expressing the BIR domains
were still viable after 96 hours, at which time no viable
cells remained in the control, i.e. non-transfected, cell
cultures (see "CHO" in Fig. 15A), and less than 5% of the
cells transfected with the vector only, i.e., lacking a
35 cDNA insert, remained viable (see "pcDNA3" in Fig. 15A).
Deletion of any of the BIR domains results in the

f
- 31 -
complete loss of apoptotic suppression, which is
reflected by a decrease in the percentage of surviving
CHO cells to control levels within 72 hours of serum
withdrawal (Fig. 15B; see "xiap~i" (which encodes amino
s acids 89-497 of XIAP (SEQ ID N0.:4)), "xiap~2" (which
.encodes amino acids 246-497 of XIAP (SEQ ID N0.:4)), and
"xiap~3" (which encodes amino acids 342-497 of XIAP (SEQ
ID N0.:4)) at 72 hours).
Stable pools of transfected CHO cells, which
~o were maintained for several months under 6418 selection,
were induced to undergo apoptosis by exposure to 10 ~M
menadione for 2 hours. Among the CHO cells tested were
those that were stably transfected with: (1) full-length
m-xiap cDNA (miap), (2) full-length xiap cDNA (xiap), (3)
is full-length bcl-2 cDNA (Bcl-2), (4) cDNA encoding the
three BIR domains (but not the RZF) of m-xiap (BIR), and
(5) cDNA encoding the RZF (but not BIR domains) of m-xiap
(RZF). Cells that were non-transfected (CHO) or
transfected with the vector only (pcDNA3), served as
zo controls for this experiment. Following exposure to 10
~,M menadione, the transfected cells were washed with
phosphate buffered saline (PBS) and cultured for an
additional 24 hours in menadione-free medium. Cell death
was assessed, as described above, by trypan blue
zs exclusion. Less than 10% of the non-transfected or
vector-only transfected cells remained viable at the end
of the 24 hour survival period. Cells expressing the RZF
did not fare significantly better. However, expression
of full-length m-xiap, xiap, or bcl-2, and expression of
3o the BIR domains, enhanced cell survival (Fig. 16A). When
the concentration of menadione was increased from 10 ~eM
to 20 ~,M (with all other conditions of the experiment
being the same as when 10 ~,M menadione was applied), the
percentage of viable CHO cells that expressed the BIR
35 domain cDNA construct was higher than the percentage of
CA 02403947 2002-10-21
f
- 32 -
viable cells that expressed either full-length m-xiap or
bcl-2 (Fig. 16B).
C. Analysis of the Subcellular Location
of Expressed RZF and BIR Domains
s The assays of cell death described above
indicate that the RZF may act as a negative regulator of
,the anti-apoptotic function of IAPs. One way in which
the RZF, and possibly other IAP domains, may exert their
regulatory influence is by altering the expression of
~o genes, whose products function in the apoptotic pathway.
In order to determine whether the subcellular
locations of expressed RZF and BIR domains are consistent
with roles as nuclear regulatory factors, CoS cells were
transiently transfected with the following four
~s constructs, and the expressed polypeptide was localized
by immunofluorescent microscopy: (1) pcDNA3-6myc-xiap,
which encodes all 497 amino acids of SEQ ID N0:4, (2)
pcDNA3-6myc-m-xiap, which encodes all 497 amino acids of
mouse xiap (SEQ ID N0:10), (3) pcDNA3-6myc-mxiap-BIR,
zo which encodes amino acids 1 to 341 of m-xiap (SEQ ID
NO:10), and (4) pcDNA3-6myc-mxiap-RZF, which encodes
amino acids 342-497 of m-xiap (SEQ ID NO:10). The cells
were grown on multi-well tissue culture slides for 12
hours, and then fixed and permeabilized with methanol.
is The constructs used (here and in the cell death assays)
were tagged with a human Myc epitope tag at the N-
terminus. Therefore, a monoclonal anti-Myc antibody and
a secondary goat anti-mouse antibody, which was
conjugated to FITC, could be used to localize the
3o expressed products in transiently transfected COS cells.
Full-length XIAP and MIAP were located in the cytoplasm,
with accentuated expression in the peri-nuclear zone.
The same pattern of localization was observed when the
cells expressed a construct encoding the RZF domain (but
35 not the BIR domains). However, cells expressing the BIR
domains (without the RZF) exhibited, primarily, nuclear
CA 02403947 2002-10-21
- 33 -
staining. The protein expressed by the BIR domain
construct appeared to be in various stages of transfer to
the nucleus.
These observations are consistent with the fact
s that, as described below, XIAP is cleaved within T cells
that are treated with anti-Fas antibodies (which are
potent inducers of apoptosis), and its N-terminal domain
is translocated to the nucleus.

~s V. Construction of a Transqenic Animal
Characterization of IAP genes provides
information that is necessary for an IAP knockout animal
model to be developed by homologous recombination.
Preferably, the model is a mammalian animal, most
2o preferably a mouse. Similarily, an animal model of IAP
overproduction may be generated by integrating one or
more IAP sequences into the genome, according to standard
transgenic techniques.
A replacement-type targeting vector, which would
zs be used to create a knockout model, can be constructed
using an isogenic genomic clone, for example, from a
mouse strain such as 129/Sv (Stratagene Inc., LaJolla,
CA). The targeting vector will be introduced into a
suitably-derived line of embryonic stem (ES) cells by
3o electroporation to generate ES cell lines that carry a
profoundly truncated form of an IAP. To generate
chimeric founder mice, the targeted cell lines will be
injected into a mouse blastula stage embryo.
Heterozygous offspring will be interbred to homozygosity.
3s Knockout mice would provide the means, in vivo, to screen
CA 02403947 2002-10-21
36
for therapeutic compounds that modulate apoptosis via an
IAP-dependent pathway.
VI. IAP Protein Expression
IAP genes may be expressed in both prokaryotic
s and eukaryotic cell types. If an IAP modulates
.apoptosis by exacerbating it, it may be desirable to
express that protein under control of an inducible
promotor.
In general, IAPs according to the invention may
~o be produced by transforming a suitable host cell with all
or part of an IAP-encoding cDNA fragment that has been
placed into a suitable expression vector.
Those skilled in the art of molecular biology
will understand that a wide variety of expression systems
~5 may be used to produce the recombinant protein. The
precise host cell used is not critical to the invention.
The IAP protein may be produced in a prokaryotic host
(e.g., E. coli) or in a eukaryotic host (e.g., S.
cerevisiae, insect cells such as Sf21 cells, or mammalian
zo cells such as COS-1, NIH 3T3, or HeLa cells). These
cells are publically available, for example, from the
American Type Culture Collection, Rockville, MD; see also
Ausubel et al., Current Protocols in Molecular Biolocty,
John Wiley & Sons, New York, NY, 1994). The method of
zs transduction and the choice of expression vehicle will
depend on the host system selected. Transformation and
transfection methods are described, e.g., in Ausubel et
al. (supra), and expression vehicles may be chosen from
those provided, e.g. in Cloning Vectors: A Laboratory
3o Manual (P. H. Pouwels et al., 1985, Supp. 1987).
A preferred expression system is the baculovirus
system using, for example, the vector pBacPAK9, which is
available from Clontech (Palo Alto, CA). If desired,
this system may be used in conjunction with other protein
3s expression techniques, for example, the myc tag approach
CA 02403947 2002-10-21
- 37 -
described by Evan et al. (Mol. Cell Biol. 5:3610-3616,
1985) .
Alternatively, an IAP may be produced by a
stably-transfected mammalian cell line. A number of
s vectors suitable for stable transfection of mammalian
cells are available to the public, e.g., see Pouwels et
al. (supra), as are methods for constructing such cell
lines (see e.g., Ausubel et al. (supra). In one example,
cDNA encoding an IAP is cloned into an expression vector
~o that includes the dihydrofolate reductase (DHFR) gene.
Integration of the plasmid and, therefore, integration of
the IAP-encoding gene into the host cell chromosome is
selected for by inclusion of 0.01-300 ~.M methotrexate in
the cell culture medium (as described, Ausubel et al.,
~s supra). This dominant selection can be accomplished in
most cell types. Recombinant protein expression can be
increased by DHFR-mediated amplification of the
transfected gene.
Methods for selecting cell lines bearing gene
zo amplifications are described in Ausubel et al. (supra).
These methods generally involve extended culture in
medium containing gradually increasing levels of
methotrexate. The most commonly used DHFR-containing
expression vectors are pCVSEII-DHFR and pAdD26SV(A)
2s (described in Ausubel et al., supra). The host cells
described above or, preferably, a DHFR-deficient CHO cell
line (e. g., CHO DHFR- cells, ATCC Accession No. CRL 9096)
are among those most preferred for DHFR selection of a
stably-transfected cell line or DHFR-mediated gene
so amplification.
Once the recombinant protein is expressed, it is
isolated by, for example, affinity chromatography. In
one example, an anti-IAP antibody, which may be produced
by the methods described herein, can be attached to a
3s column and used to isolate the IAP protein. Lysis and
CA 02403947 2002-10-21
- 38 -
fractionation of IAP-harboring cells prior to affinity
chromatography may be performed by standard methods (see
e.g., Ausubel et al., supra). Once isolated, the
recombinant protein can, if desired, be purified further
s by e.g., by high performance liquid chromatography (HPLC;
e.g., see Fisher, Laboratory Technigues In Biochemistry
And Molecular Biolocty, work and Burdon, Eds., Elsevier,
1980) .
Polypeptides of the invention, particularly
~o short IAP fragments, can also be produced by chemical
synthesis (e. g., by the methods described in Solid Phase
Peptide Synthesis, 2nd ed., 1984 The Pierce Chemical Co.,
Rockford, IL). These general techniques of polypeptide
expression and purification can also be used to produce
~s and isolate useful IAP fragments or analogs, asdescribed
herein.
VII. Anti-IAP Antibodies
In order to generate IAP-specific antibodies, an
IAP coding sequence (i.e., amino acids 180-276) can be
Zo expressed as a C-terminal fusion with glutathione S-
transferase (GST; Smith et al., Gene 67:31-40, 1988).
The fusion protein can be purified on glutathione-
Sepharose beads, eluted with glutathione, and cleaved
with thrombin (at the engineered cleavage site), and
zs purified to the degree required to successfully immunize
rabbits. Primary immunizations can be carried out with
Freund's complete adjuvant and subsequent immunizations
performed with Freund's incomplete adjuvant. Antibody
titres are monitored by Western blot and
3o immunoprecipitation analyses using the thrombin-cleaved
IAP fragment of the GST-IAP fusion protein. Immune sera
are affinity purified using CNBr-Sepharose-coupled IAP
protein. Antiserum specificity is determined using a
panel of unrelated GST proteins (including GSTp53, Rb,
CA 02403947 2002-10-21
- 39 -
HPV-16 E6, and E6-AP) and GST-trypsin (which was
generated by PCR using known sequences).
As an alternate or adjunct immunogen to GST
fusion proteins, peptides corresponding to relatively
s unique hydrophilic regions of IAP may be generated and
coupled to keyhole limpet hemocyanin (KLH) through an
introduced C-terminal lysine. Antiserum to each of these
peptides is similarly affinity purified on peptides
conjugated to BSA, and specificity is tested by ELISA and
to Western blotting using peptide conjugates, and by Western
blotting and immunoprecipitation using IAP expressed as a
GST fusion protein.
Alternatively, monoclonal antibodies may be
prepared using the IAP proteins described above and
t5 standard hybridoma technology (see, e.g., Kohler et al.,
Nature 256:495, 1975; Kohler et al., Eur. J. Immunol.
6:511, 1976;
Kohler et al., Eur. J. Immunol. 6:292, 1976; Hammerling
et al., In Monoclonal Antibodies and T Cell Hvbridomas,
za Elsevier, New York, NY, 1981; Ausubel et al., supra).
once produced, monoclonal antibodies are also tested for
specific IAP recognition by Western blot or
immunoprecipitation analysis (by the methods described in
Ausubel et al., supra).
z5 Antibodies that specifically recognize IAPs or
fragments of IAPs, such as those described herein
containing one or more BIR domains (but not a ring zinc
finger domain), or that contain a ring zinc finger domain
(but not a BIR domain) are considered useful in the
3o invention. They may, for example, be used in an
immunoassay to monitor IAP expression levels or to
determine the subcellular location of an IAP or IAP
fragment produced by a mammal. Antibodies that inhibit
the 26 kDa IAP cleavage product described herein (which
3s contains at least one BIR domain) may be especially
CA 02403947 2002-10-21
- 40 -
useful in inducing apoptosis in cells undergoing
undesirable proliferation.
Preferably, antibodies of the invention are
produced using IAP sequence that does not reside within
s highly conserved regions, and that appears likely to be
antigenic, as analyzed by criteria such as those provided
by the Peptide structure program (Genetics Computer Group
Sequence Analysis Package, Program Manual for the GCG
Package, Version 7, 1991) using the algorithm of Jameson
~o and Wolf (CABIOS 4:181, 1988). Specifically, these
regions, which are found between BIR1 and BIR2 of all
IAPs, are: from amino acid 99 to amino acid 170 of hiap-
1, from amino acid 123 to amino acid 184 of hiap-2, and
from amino acid 116 to amino acid 133 of either xiap or
~s m-xiap. These fragments can be generated by standard
techniques, e.g. by the PCR, and cloned into the pGEX
expression vector (Ausubel et al., supra). Fusion
proteins are expressed in E. coli and purified using a
glutathione agarose affinity matrix as described in
zo Ausubel et al. (supra). In order to minimize the
potential for obtaining antisera that is non-specific, or
exhibits low-affinity binding to IAP, two or three
fusions are generated for each protein, and each fusion
is injected into at least two rabbits. Antisera are
zs raised by injections in series, preferably including at
least three booster injections.
VIII. Identification of Molecules that
Modulate IAP Protein Expression
Isolation of IAP cDNAs also facilitates the
3o identification of molecules that increase or decrease IAP
expression. In one approach, candidate molecules are
added, in varying concentration, to the culture medium of
cells expressing IAP mRNA. IAP expression is then
measured, for example, by Northern blot analysis (Ausubel
3s et al., supra) using an IAP cDNA, or cDNA fragment, as a
hybridization probe (see also Table 5). The level of IAP
CA 02403947 2002-10-21
_ 41
expression in the presence of the candidate molecule is
compared to the level of IAP expression in the absence of
the candidate molecule, all other factors (e. g. cell type
and culture conditions) being equal.
s The effect of candidate molecules on IAP-
mediated apoptosis may, instead, be measured at the level
of translation by using the general approach described
above with standard protein detection techniques, such as
Western blotting or immunoprecipitation with an IAP-
~o specific antibody (for example, the IAP antibody
described herein).
Compounds that modulate the level of IAP may be
purified, or substantially purified, or may be one
component of a mixture of compounds such as an extract or
~s supernatant obtained from cells (Ausubel et al., supra).
In an assay of a mixture of compounds, IAP expression is
tested against progressively smaller subsets of the
compound pool (e. g., produced by standard purification
techniques such as HPLC or FPLC) until a single compound
zo or minimal number of effective compounds is demonstrated
to modulate IAP expression.
Compounds may also be screened for their ability
to modulate IAP apoptosis inhibiting activity. In this
approach, the degree of apoptosis in the presence of a
zs candidate compound is compared to the degree of apoptosis
in its absence, under equivalent conditions. Again, the
screen may begin with a pool of candidate compounds, from
which one or more useful modulator compounds are isolated
in a step-wise fashion. Apoptosis activity may be
3o measured by any standard assay, for example, those
described herein.
Another method for detecting compounds that
modulate the activity of IAPs is to screen for compounds
that interact physically with a given IAP polypeptide.
ss These compounds may be detected by adapting interaction
CA 02403947 2002-10-21
trap expression systems known in the art. These systems
detect protein interactions using a transcriptional
activation assay and are generally described by Gyuris et
al. (Cell 75:791-803, 1993) and Field et al., Nature
s 340:245-246, 1989), and are commercially available from
Clontech (Palo Alto, CA). In addition, PCT Publication
WO 95/28497 describes an interaction trap assay in which
proteins involved in apoptosis, by virtue of their
interaction with Bcl-2, are detected. A similar method
~o may be used to identify proteins and other compounds that
interact with IAPs.
Compounds or molecules that function as
modulators of IAP-mediated cell death may include peptide
and non-peptide molecules such as those present i.n cell
i5 extracts, mammalian serum, or growth medium in which
mammalian cells have been cultured.
A molecule that promotes an increase i~ IAP
expression or IAP activity is considered particularly
useful in the invention; such a molecule may be used, for
zo example, as a therapeutic to increase cellular levels of
IAP and thereby exploit the ability of IAP polypgptides
to inhibit apoptosis.
A molecule that decreases IAP activity y(e.g., by
decreasing IAP gene expression or polypeptide activity)
is may be used to decrease cellular proliferation. This
would be advantageous in the treatment of neoplasms (see
Table 3, below), or other cell proliferative diseases.

described above, to effectively modulate IAP gene

in animal models. If they continue to function
successfully in an in vivo setting, they may be used as
zo therapeutics to either inhibit or enhance apoptosis, as
appropriate.
IX. IAP Therany
The level of IAP gene expression correlates with
the level of apoptosis. Thus, IAP genes also find use in
z5 anti-apoptosis gene therapy. In particular, a functional
IAP gene may be used to sustain neuronal cells that
undergo apoptosis in the course of a neurodegenerative
disease, lymphocytes (i.e., T cells and B cells), or
cells that have been injured by ischemia.
3o Retroviral vectors, adenoviral vectors, adeno-
associated viral vectors, or other viral vectors with the
appropriate tropism for cells likely to be involved in
CA 02403947 2002-10-21
44
apoptosis (for example, epithelial cells) may be used as
a gene transfer delivery system for a therapeutic IAP
gene construct. Numerous vectors useful for this purpose
are generally known (Miller, Human Gene Therapy 15-14,
s 1990; Friedman, Science 244:1275-1281, 1989; Eglitis and
Anderson, BioTechniques 6:608-614, 1988; Tolstoshev and

Retroviral vectors are particularly well developed and
~s have been used in clinical settings (Rosenberg et al., N.
Engl. J. Med 323:370, 1990; Anderson et al., U.S. Patent
No. 5,399,346). Non-viral approaches may also be
employed for the introduction of therapeutic DNA into
cells otherwise predicted to undergo apoptosis. For
zo example, IAP may be introduced into a neuron or a T cell
by lipofection (Felgner et al., Proc. Natl. Acad. Sci.
USA 84:7413, 1987; Ono et al., Neurosci. Lett. 117:259,
1990; Brigham et al., Am. J. Med. Sci. 298:278, 1989;
Staubinger et al., Meth. Enz. 101:512, 1983),
2s asialorosonucoid-polylysine conjugation (Wu et al., J.
Biol. Chem. 263:14621, 1988; Wu et al., J. Biol. Chem.
264:16985, 1989); or, less preferably, microinjection
under surgical conditions (Wolff et al., Science
247:1465, 1990).
so For any of the methods of application described
above, the therapeutic IAP DNA construct is preferably
applied to the site of the predicted apoptosis event (for
example, by injection). However, it may also be applied
to tissue in the vicinity of the predicted apoptosis
CA 02403947 2002-10-21
- 45 -
event or to a blood vessel supplying the cells predicted
to undergo apoptosis.
In the constructs described, IAP cDNA expression
can be directed from any suitable promoter (e.g., the
s human cytomegalovirus (CMV), simian virus 40 (SV40), or
metallothionein promoters), and regulated by any
appropriate mammalian regulatory element. For example,
if desired, enhancers known to preferentially direct gene
expression in neural cells, T cells, or B cells may be
~o used to direct IAP expression. The enhancers used could
include, without limitation, those that are characterized
as tissue- or cell-specific in their expression.
Alternatively, if an IAP genomic clone is used as a
therapeutic construct (for example, following its
isolation by hybridization with the IAP cDNA described
above), regulation may be mediated by the cognate
regulatory sequences or, if desired, by regulatory
sequences derived from a heterologous source, including
any of the promoters or regulatory elements described
Zo above .
Less preferably, IAP gene therapy is
accomplished by direct administration of the IAP mRNA or
antisense IAP mRNA to a cell that is expected to undergo
apoptosis. The mRNA may be produced and isolated by any
z5 standard technique, but is most readily produced by in
vitro transcription using an IAP cDNA under the control
of a high efficiency promoter (e. g., the T7 promoter).
Administration of IAP mRNA to malignant cells can be
carried out by any of the methods for direct nucleic acid
3o administration described above.
Ideally, the production of IAP protein by any
gene therapy approach will result in cellular levels of
IAP that are at least equivalent to the normal, cellular
level of IAP in an unaffected cell. Treatment by any
CA 02403947 2002-10-21
- 46 -
IAP-mediated gene therapy approach may be combined with
more traditional therapies.
Another therapeutic approach within the
invention involves administration of recombinant IAP
s protein, either directly to the site of a predicted
apoptosis event (for example, by injection) or
systemically (for example, by any conventional
recombinant protein administration technique). The
dosage of IAP depends on a number of factors, including
~o the size and health of the individual patient, but,
generally, between O.1 mg and 100 mg inclusive are
administered per day to an adult in any pharmaceutically-
acceptable formulation.
X. Administration of IAP Polypeptides, IAP
i5 Genes. or Modulators of IAP Synthesis or Function
An IAP protein, gene, or modulator may be
administered within a pharmaceutically-acceptable
diluent, carrier, or excipient, in unit dosage form.
Conventional pharmaceutical practice may be employed to
2o provide suitable formulations or compositions to
administer IAP to patients suffering from a disease that
is caused by excessive apoptosis. Administration may
begin before the patient is symptomatic. Any appropriate
route of administration may be employed, for example,
2s administration may be parenteral, intravenous,
intraarterial, subcutaneous, intramuscular, intracranial,
intraorbital, ophthalmic, intraventricular,
intracapsular, intraspinal, intracisternal,
intraperitoneal, intranasal, aerosol, or oral
3o administration. Therapeutic formulations may be in the
form of liquid solutions or suspensions; for oral
administration, formulations may be in the form of
tablets or capsules; and for intranasal formulations, in
the form of powders, nasal drops, or aerosols.
3s Methods well known in the art for making
formulations are found, for example, in "Remington's
CA 02403947 2002-10-21
- 47 -
Pharmaceutical Sciences." Formulations for parenteral
administration may, for example, contain excipients,
sterile water, or saline, polyalkylene glycols such as
polyethylene glycol, oils of vegetable origin, or
s hydrogenated napthalenes. Biocompatible, biodegradable
,lactide polymer, lactide/glycolide copolymer, or
polyoxyethylene-polyoxypropylene copolymers may be used
to control the release of the compounds. Other
potentially useful parenteral delivery systems for IAP
~o modulatory compounds include ethylene-vinyl acetate
copolymer particles, osmotic pumps, implantable infusion
systems, and liposomes. Formulations for inhalation may
contain excipients, for example, lactose, or may be
aqueous solutions containing, for example,
~s polyoxyethylene-9-lauryl ether, glycocholate and
deoxycholate, or may be oily solutions for administration
in the form of nasal drops, or as a gel.
If desired, treatment with an IAP protein, gene,
or modulatory compound may be combined with more
zo traditional therapies for the disease such as surgery,
steroid therapy, or chemotherapy for autoimmune disease;
antiviral therapy for AIDS; and tissue plasminogen
activator (TPA) for ischemic injury.
XI. Detection of Conditions Involving
zs Altered Apoptosis
IAP polypeptides and nucleic acid sequences find
diagnostic use in the detection or monitoring of
conditions involving aberrant levels of apoptosis. For
example, decrease expression of IAP may be correlated
3o with enhanced apoptosis in humans (see XII, below).
Accordingly, a decrease or increase in the level of IAP
production may provide an indication of a deleterious
condition. Levels of IAP expression may be assayed by
any standard technique. For example, IAP expression in a
ss biological sample (e.g., a biopsy) may be monitored by
standard Northern blot analysis or may be aided by PCR
CA 02403947 2002-10-21
- 48 -
(see, e.g., Ausubel et al., supra; PCR Technolocty:
Principles and Applications for DNA Amplification, H.A.
Ehrlich, Ed. Stockton Press, NY; Yap et al. Nucl. Acids.
Res. 19:4294, 1991).
s Alternatively, a biological sample obtained from
a patient may be analyzed for one or more mutations in
the IAP sequences using a mismatch detection approach.
Generally, these techniques involve PCR amplification of
nucleic acid from the patient sample, followed by
to identification of the mutation (i.e., mismatch) by either
altered hybridization, aberrant electrophoretic gel
migration, binding or cleavage mediated by mismatch
binding proteins, or direct nucleic acid sequencing. Any
of these techniques may be used to facilitate mutant IAP
is detection, and each is well known in the art; examples of
particular techniques are described, without limitation,
in Orita et al., Proc. Natl. Acad. Sci. USA 86:2766-
2770, 1989; Sheffield et al., Proc. Natl. Acad. Sci. USA
86:232-236, 1989).
zo In yet another approach, immunoassays are used
to detect or monitor IAP protein in a biological sample.
IAPspecific polyclonal or monoclonal antibodies (produced
as described above) may be used in any standard
immunoassay format (e.g., ELISA, Western blot, or RIA) to
zs measure IAP polypeptide levels. These levels would be
compared to wild-type IAP levels, with a decrease in IAP
production indicating a condition involving increased
apoptosis. Examples of immunoassays are described, e.g.,
in Ausubel et al., supra. Immunohistochemical techniques
3o may also be utilized for IAP detection. For example, a
tissue sample may be obtained from a patient, sectioned,
and stained for the presence of IAP using an anti-IAP
antibody and any standard detection system (e.g., one
which includes a secondary antibody conjugated to
ss horseradish peroxidase). General guidance regarding such
CA 02403947 2002-10-21
- 49 -
techniques can be found in, e.g., Bancroft and Stevens
(Theory and Practice of Histoloctical Techniques,
Churchill Livingstone, 1982) and Ausubel et al. (supra).
In one preferred example, a combined diagnostic
s method may be employed that begins with an evaluation of
.IAP protein production (for example, by immunological
techniques or the protein truncation test (Hogerrorst et
al., Nature Genetics 10:208-212, 1995) and also includes
a nucleic acid-based detection technique designed to
~o identify more subtle IAP mutations (for example, point
mutations). As described above, a number of mismatch
detection assays are available to those skilled in the
art, and any preferred technique may be used. Mutations
in IAP may be detected that either result in loss of IAP
~s expression or loss of IAP biological activity. In a
variation of this combined diagnostic method, IAP
biological activity is measured as protease activity
using any appropriate protease assay system (for example,
those described above).
zo Mismatch detection assays also provide an
opportunity to diagnose an IAP-mediated predisposition to
diseases caused by inappropriate apoptosis. For example,
a patient heterozygous for an IAP mutation may show no
clinical symptoms and yet possess a higher than normal
is probability of developing one or more types of
neurodegenerative, myelodysplastic or ischemic diseases.
Given this diagnosis, a patient may take precautions to
minimize their exposure to adverse environmental factors
(for example, W exposure or chemical mutagens) and to
so carefully monitor their medical condition (for example,
through frequent physical examinations). This type of
IAP diagnostic approach may also be used to detect IAP
mutations in prenatal screens. The IAP diagnostic assays
described above may be carried out using any biological
ss sample (for example, any biopsy sample or bodily fluid or
CA 02403947 2002-10-21
- 50 -
tissue) in which IAP is normally expressed.
Identification of a mutant IAP gene may also be assayed
using these sources for test samples.
Alternatively, a IAP mutation, particularly as
part of a diagnosis for predisposition to IA.P-associated
,degenerative disease, may be tested using a DNA sample
from any cell, for example, by mismatch detection
techniques. Preferably, the DNA sample is subjected to
PCR amplification prior to analysis.
~o In order to demonstrate the utility of IAP gene
sequences as diagnostics and prognostics for cancer, a
Human Cancer Cell Line Multiple Tissue Northern Blot
(Clontech, Palo Alto, CA; #7757-1) was probed. This
Northern blot contained approximately 2 ~Cg of poly A+ RNA
5 per lane from eight different human cell lines: (1)
promyelocytic leukemia HL-60, (2) HeLa cell S3, (3)
chronic myelogenous leukemia K-562, (4) lymphoblastic
leukemia MOLT-4, (5) Burkitt's lymphoma Raji, (6)
colorectal adenocarcinoma SW480, (7) lung carcinoma A549,
zo and (8) melanoma 6361. As a control, a Human Multiple
Tissue Northern Blot (Clontech, Palo Alto, CA; ,7759-1)
was probed. This Northern blot contained approximately 2
~cg of poly A+ RNA from eight different human tissues:
(1) spleen, (2) thymus, (3) prostate, (4) testis, (5)
z5 ovary, (6) small intestine, (7) colon, and (8) peripheral
blood leukocytes.
The Northern blots were hybridized sequentially
with: (1) a 1.6 kb probe to the xiap coding region, (2)
a 375 by hiap-2 specific probe corresponding to the
so 3' untranslated region, (3) a 1.3 kb probe to the coding
region of hiap-1, which cross-reacts with hiap-2, (4) a
1.0 kb probe derived from the coding region of bcl-2, and
(5) a probe to ~-actin, which was provided by the
manufacturer. Hybridization was carried out at 50°C
35 overnight, according to the manufacturer's suggestion.
CA 02403947 2002-10-21
- 51 -
The blot was washed twice with 2X SSC, 0.1% SDS at room
temperature for 15 minutes and then with 2X SSC, 0.1% SDS
at 50°C.
All cancer lines tested showed increased IAP
s expression relative to samples from non-cancerous control
.tissues (Table 3). Expression of xiap was particularly
high in HeLa (S-3), chronic myelogenous leukemia (K-562),
colorectal adenocarcinoma (SW-480), and melanoma (G-361)
lines. Expression of hiap-1 was extremely high in
1o Burkitt's lymphoma, and was also elevated in colorectal
adenocarcinoma. Expression of hiap-2 was particularly
high in chronic myelogenous leukemia (K-562) and
colorectal adenocarcinoma (SW-480). Expression of Bcl-2
was upregulated only in HL-60 leukemia cells.
t5 These observations suggest that upregulation of
the anti-apoptotic IAP genes may be a widespread
phenomenon, perhaps occurring much more frequently than
upregulation of Bcl-2. Furthermore, upregulation may be
necessary for the establishment or maintenance of the
zo transformed state of cancerous cells.
In order to pursue the observation described
above, i.e., that hiap-1 is overexpressed in the Raji
Burkitt's lymphoma cell line, RT-PCR analysis was
performed in multiple Burkitt's lymphoma cell lines.
zs Total RNA was extracted from cells of the Raji, Ramos,
EB-3, and Jiyoye cell lines, and as a positive control,
from normal placental tissue. The RNA was reverse
transcribed, and amplified by PCR with the following set
of oligonucleotide primers:
30 5'-AGTGCGGGTTTTTATTATGTG-3' (SEQ ID NO: ) and
5'-AGATGACCACAAGGAATAAACACTA-3' (SEQ ID NO: ), which
selectively amplify a hiap-1 cDNA fragment. RT-PCR was
conducted using a PerkinElmer 480 Thermocycler to carry
out 35 cycles of the following program: 94°C for 1
s5 minute, 50°C for 1.5 minutes, and 72°C for a minute. The
CA 02403947 2002-10-21
t
- 52 -
PCR reaction product was electrophoresed on an agarose
gel and stained with Ethidium bromide. Amplified cDNA
fragments of the appropriate size were clearly visible in
all lanes containing Burkitt's lymphoma samples, but
s absent in the lanes containing the normal placental
tissue sample, and absent in lanes containing negative
control samples, where template DNA was omitted from the
reaction (Fig. 17).
XII. Accumulation of a 26 kDa
to Cleavacte Protein in Astrocytoma Cells
A. Identification of a 26 kDa Cleavage Protein
A total protein extract was prepared from Jurkat
and astrocytoma cells by sonicating them (X3 for 15
seconds at 4°C) in 50 mM Tris-HC1 (pH 8.0), 150 mM NaCl,
is 1 mM PMSF, 1 ~g/ml aprotinin, and 5 mM benzamidine.
Following sonication, the samples were centrifuged
(14,000 RPM in a microfuge) for five minutes. Twenty ~Cg
of protein was loaded per well on a 10~ SDS-
polyacrylamide gel, electrophoresed, and electroblotted
zo by standard methods to PVDF membranes. Western blot
analysis, performed as described previously, revealed
that the astrocytoma cell line (CCF-STTG1) abundantly
expressed an anti-xiap reactive band of approximately 26
kDa, despite the lack of an apoptotic trigger event (Fig.
z5 18). In fact, this cell line has been previously
characterized as being particularly resistant to standard
apoptotic triggers.
A 26 kDa xiap-reactive band was also observed
under the following experimental conditions. Jurkat
3o cells (a transformed human T cell line) were induced to
undergo apoptosis by exposure to an anti-Fas antibody (1
~tg/ml). Identical cultures of Jurkat cells were exposed
either to: (1) anti-Fas antibody and cycloheximide (20
~,g/ml), (2) tumor necrosis factor alpha (TNF-a, at 1,000
35 U/ml), or (3) TNF-a and cycloheximide (20 ~Cg/ml). All
cells were harvested 6 hours after treatment began. In
CA 02403947 2002-10-21
- 53 -
addition, as a negative control, anti-Fas antibody was
added to an extract after the cells were harvested. The
cells were harvested in SDS sample buffer,
electrophoresed on a 12.5% SDS polyacrylamide gel, and
s electroblotted onto PVDF membranes using standard
methods. The membranes were immunostained with a rabbit
polyclonal anti-XIAP antibody at 1:1000 for 1 hour at
room temperature. Following four 15 minute washes, a
goat anti-rabbit antibody conjugated to horse-radish
~o peroxidase was applied at room temperature for 1 hour.
Unbound secondary antibody was washed away, and
chemiluminescent detection of XIAP protein was performed.
The Western blot revealed the presence of the full-
length, 55 kDa XIAP protein, both in untreated and
is treated cells. In addition, a novel, approximately 26
kDa xiap-reactive band was also observed in apoptotic
cell extracts, but not in the control, untreated cell
extracts (Fig. 19).
Cleavage of XIAP occurs in a variety of cell
2o types, including other cancer cell lines such as HeLa.
The expression of the 26 kDa XIAP cleavage product was
demonstrated in HeLa cells as follows. HeLa cells Were
treated with either: (1) cyclohexamide (20 ~Cg/ml),
(2) anti-Fas antibody (1 ~.g/ml), (3) anti-Fas antibody
zs (1 ~g/ml) and cyclohexamide (20 ug/ml), (4) TNFa
(1,000 U/ml), or (5) TNFa (1,000 U/ml) and cyclohexamide
(20 ~g/ml). All cells were harvested 18 hours after
treatment began. As above, anti-Fas antibody was added
to an extract after the cells were harvested. HeLa cells
3o were harvested, and the Western blot was probed under the
same conditions as used to visualize xiap-reactive bands
from Jurkat cell samples. A 26 kDa XIAP band was again
seen in the apoptotic cell preparations (Fig. 20).
Furthermore, the degree of XIAP cleavage correlated
35 positively with the extent of apoptosis. Treatment of
CA 02403947 2002-10-21
- 54 -
HeLa cells with cycloheximide or TNFa alone caused only
minor apoptosis, and little cleavage product was
observed. If the cells were treated with the anti-Fas
antibody, a greater amount of cleavage product was
s apparent. These data indicate that XIAP is cleaved in
more than one cell type and in response to more than one
type of apoptotic trigger.
B. Time Course of Expression
The time course over which the 26 kDa cleavage
~o product accumulates was examined by treating HeLa and
Jurkat cells with anti-Fas antibody (1 ~Cg/ml) and
harvesting them either immediately, or 1, 2, 3, 5, 10, or
22 hours after treament. Protein extracts were prepared
and Western blot analysis was performed as described
~s above. Both types of cells accumulated increasing
quantities of the 26 kDa cleavage product over the time
course examined (Figs. 21A and 21B).
_C. Subcellular Localization of
the 26 kDa XIAP Cleavage Product
zo In order to determine the subcellular location
of the 26 kDa cleavage product, Jurkat cells were induced
to undergo apoptosis by exposure to anti-Fas antibody
(1 ug/ml) and were then harvested either immediately, 3
hours, or 7 hours later. Total protein extracts were
zs prepared, as described above, from cells harvested at
each time point. In order to prepare nuclear and
cytoplasmic cell extracts, apoptotic Jurkat cells were
washed with isotonic Tris buffered saline (pH 7.0) and
lysed by freezing and thawing five times in cell
3o extraction buffer (50 mM PIPES, 50 mM KC1, 5 mM EGTA, 2
mM MgCl2, 1 mM DTT, and 20 ACM cytochalasin B). Nuclei
were pelleted by centrifugation and resuspended in
isotonic Tris (pH 7.0) and frozen at -80°C. The
cytoplasmic fraction of the extract was processed further
35 by centrifugation at 60,000 RPM in a TA 100.3 rotor for
30 minutes. Supernatants were removed and frozen at -
CA 02403947 2002-10-21
,;962-52 (S)
- 55 -
80°C. Samples of both nuclear and cytoplasmic fractions
were loaded on a 12.5% SDS-polyacrylamide gel, and
electroblotted onto PVDF membranes. Western blot
analysis was then performed using either an anti-CPP32
antibody (Transduction Laboratories Lexington, KY; Fig.
22A) or the rabbit anti-XIAP antibody described above
(Fig. 22B).
The anti-CPP32 antibody, which recognizes the
CPP32 protease (also known as YAMA or,Apopain)
~o partitioned almost exclusively in the cytoplasmic
fraction. The 55 kDa XIAP protein localized exclusively
in the cytoplasm of apoptotic cells, in agreement with
the studies presented above, where XIAP protein in
normal, healthy COS cells was seen to localize, by
~5~~ immunofluoresence microscopy, to the cytoplasm. In
contrast, the 26 kDa cleavage product localized
exclusively to the nuclear fraction of apoptotic Jurkat
cells. Taken together, these observations suggest that
the anti-apoptotic component of XIAP could be the 26 kDa
zo cleavage product, which exerts its influence within the
nucleus.
D. In vitro Cleavaqe oL XIAP Drotein and
Characterization of the Cleavage Product
For this series of experiments, XIAP protein was
z5 labeled with 35S using the plasmid pcDNA3-6myc-XIAP, T7
RNA poly~erase, and a coupled transcription/translation
kit (Promega) according to the manufacturer's
instructions. Radioactively labeled XIAP protein was
separated from unincorporated methionine by column
so chromatography using Sephadex G-SO~. In addition,
extracts of apoptotic Jurkat cells were prepared
following treatment with anti-Fas antibody (1 ~g/ml) for
three hours. To prep*re the extracts, the cells were
lysed in Triton X-lOC buffer (1% Triton X-100, 25 mM Tris
3s HC1) on ice for two hours and then microcentrifuged for 5
minutes. The soluble extract was retained (and was
*Trade-mark
CA 02403947 2002-10-21
.6962-52 (S)
- 56 -
labeled TX100). Cells were lysed in cell extraction
buffer with freeze/thawing. The soluble cytoplasmic
fraction was set aside (and labeled CEB). Nuclear
pellets from the preparation of the CEB cytoplasmic
s fraction were solubilized with Triton X-100 buffer,
microcentrifuged, and the soluble fractions, which
contains primarily nuclear DNA, was retained (and labeled
CEB-TX100). Soluble cell extract was prepared by lysing
cells with NP-40 buffer, followed by microcentrifugation
~o for 5 minutes (and was labeled NP-40). In vitro cleavage
was performed by incubating 16 ~1 of each extract (CEB,
TX-100, CEB-TX100, and NP-40) with 4 ~1 of in vitro
translated XIAP protein at 37°C for 7 hours. Negative
controls, containing only TX100 buffer or CEB buffer were
~5 also included- The proteins were separated on a 10% SDS-
polyacrylanide gel, which was dried and exposed to X-ray
film overnight.
In vitro cleavage of XIAP was apparent in the
CEB extract. The observed molecular weight of the
Zo cleavage product was approximately 36 kDa (Fig. 23). The
kDa shift in the size of the cleavage product
indicates that the observed product is derived frors the
amino-terminus of the recombinant protein, which contains
six copies of the myc epitope (l0 kDa). It thus appears
zs that the cleavage product possesses at least two of the
BIR domains, and that it is localized to the nucleus.
XIII. Treatment of HIV Infected Individuals
The expression of hiap-1 and hiap-2 is decreased
significantly in HIV-infected human cells. Furthermore,
3o this decrease precedes apoptosis. Therefore,
administration of HIAP-1, HIAP-2, genes encoding these
proteins, or compounds that upregulate these genes can be
used to prevent T cell attrition in HIV-infected
patients. The following assay may also be used to screen
*Trade-mark
CA 02403947 2002-10-21
- sT -
for compounds that alter hiap-1 and hiap-2 expression,
and which also prevent apoptosis.
Cultured mature lymphocyte CD-4+ T cell lines
(H9, labelled "a"; CEM/CM-3, labelled "b"; 6T-CEM,
s labelled "c"; and Jurkat, labelled "d" in Figs. 13A and
13B), were examined for signs of apoptosis (Fig. 13A) and
hiap gene expression (Fig. 13B) after exposure to
mitogens or HIV infection. Apoptosis was demonstrated by
the appearance of DNA "laddering" upon gel
io electrophoresis and gene expression was assessed by PCR.
The results obtained from normal (non-infected, non-
mitogen stimulated) cells are shown in each lane labelled
"1" in Figs. 13A and 13B. The results obtained 24 hours
after PHA/PMA (phytohemagglutinin/phorbol ester)
~s stimulation are shown in each lane labelled "2". The
results obtained 24 hours after HIV strain IIIB infection
are shown in each lane labelled "3". The "M" refers to
standard DNA markers (the 123 by ladder in Fig. 138, and
the lambda HindIII ladder in Fig. 13A (both from Gibco-
zo BRL)). DNA ladders (Prigent et al., J. Immunol. Methods,
160:139-140, 1993), which indicate apoptosis, are evident
when DNA from the samples described above are
electrophoresed on an ethidium bromide-stained agarose
gel (Fig. 13A). The sensitivity and degree of apoptosis
zs of the four T cell lines tested varies following mitogen
stimulation and HIV infection.
In order to examine hiap gene expression, total
RNA was prepared from the cultured cells and reverse
transcribed using oligo-dT priming. The RT cDNA products
3o were amplified by PCR using specific primers (as shown in
Table 5) for the detection of hiap-2a, hiap-2b and hiap-
1. The PCR was conducted using a PerkinElmer 480
thermocycler with 35 cycles of the following program:
94°C for one minute, 55°C for 2 minutes and 72°C for 1.5
3s minutes. The RT-PCR reaction products were
CA 02403947 2002-10-21
- 58 -
electrophoresed on a 1% agarose gel, which was stained
with ethidium bromide. Absence of hiap-2 transcripts is
noted in all four cell lines 24 hours after HIV
infection. In three of four cell lines (all except H9),
s the hiap-1 gene is also dramatically down-regulated after
HIV infection. PHA/PMA mitogen stimulation also appears
to decrease hiap gene expression; particularly of hiap-2
and to a lesser extent, of hiap-1. The data from these
experiments is summarized in Table 5. The expression of
to ~-actin was consistent in all cell lines tested,
indicating that there is not a flaw in the RT-PCR assay
that could account for the decrease in hiap gene
expression.

XIV. Ass~crnment of xiap. hiap-1, and hia~-2 to
Chromosomes Xq25 and 11c~22-23 by
Fluorescence in situ Hybridization
FISH
s Fluorescence in situ hybridization (FISH) was
used to identify the chromosomal location of xiap, hiap-1
and hiap-2. The probes used were cDNAs cloned in plasmid
vectors: the 2.4 kb xiap clone included 1493 by of
coding sequence, 34bp of 5' UTR (untranslated region) and
~0 913 by of 3'UTR; the hiap-1 cDNA was 3.1 kb long and
included 1812 by coding and 1300 by of 3' UTR; and the
hiap-2 clone consisted of 1856 by of coding and 1200 by
of 5' UTR. A total of 1 ~g of probe DNA was labelled
with biotin by nick translation (BRL). Chromosome
~s spreads prepared from a normal peripheral blood culture
were denatured for 2 minutes at 70°C in 50% formamide/2X
SSC and subsequently hybridized with the biotin labelled
DNA probe for 18 hours at 37°C in a solution consisting
of 2X SSC/70% formamide/10% dextran sulfate. After
zo hybridization, the spreads were washed in
2X SSC/50% formamide, followed by a wash in 2X SSC at
42°C. The biotin labelled DNA was detected~by~
fluorescein isothiocyanate (FITC) conjugated avidin
antibodies and anti-avidin antibodies (ONCOR detection
zs kit), according to the manufacturer's instructions.
Chromosomes were counterstained with propidium iodide and
examined with a Olympus BX60 epifluorescence microscope.
For chromosome identification, the slides with recorded
labelled metaphase spreads were destained, dehydrated,
3o dried, digested with trypsin for 30 seconds and stained
with 4% Giemsa stain for 2 minutes. The chromosome
spreads were relocated and the images were compared.
A total of 101 metaphase spreads were examined
with the xiap probe, as described above. Symmetrical
35 fluorescent signals on either one or both homologs of
CA 02403947 2002-10-21
- bt -
chromosome Xq25 were observed in 74% of the cells
analyzed. Following staining with hiap-1 and hiap-2
probes, 56 cells were analyzed and doublet signals in the
region 11q22-23 were observed in 83% of cells examined.
s The xiap gene was mapped to Xq25 while the hiap-1 and
hiap-2 genes were mapped at the border of 11q22 and 11q23
bands.
These experiments confirmed the location of the
xiap gene on chromosome Xq25. No highly consistent
to chromosomal abnormalities involving band Xq25 have been
reported so far in any malignancies. However, deletions
within this region are associated with a number of immune
system defects including X-linked lymphoproliferative
disease (Wu et al., Genomics 17:163-170, 1993).
t5 Cytogenetic abnormalities of band 11q23 have
been identified in more than 50% of infant leukemias
regardless of the phenotype (Martinez-Climet et al.,
Leukaemia 9:1299-1304, 1995). Rearrangements of the MLL
Gene (mixed lineage leukemia or myeloid lymphoid
20 leukemia; Ziemin Van der Poel et al., Proc. Natl. Acad.
Sci. USA 88:10735-10739, 1991) have been detected in 80%
of cases with 11q23 translocation, however patients whose
rearrangements clearly involved regions other than the
MLL gene were also reported (Kobayashi et al., Blood
is 82:547-551, 1993). Thus, the IAP genes may follow the
Bcl-2 paradigm, and would therefore play an important
role in cancer transformation.
XV. Preventive Anti-Apoptotic Therapy
In a patient diagnosed to be heterozygous for an
3o IAP mutation or to be susceptible to IAP mutations (even
if those mutations do not yet result in alteration or
loss of IAP biological activity), or a patient diagnosed
as HIV positive, any of the above therapies may be
administered before the occurrence of the disease
CA 02403947 2002-10-21
r
- 62 -
phenotype. For example, the therapies may be provided to
a patient who is HIV positive but does not yet show a
diminished T cell count or other overt signs of AIDS. In
particular, compounds shown to increase IAP expression or
s IAP biological activity may be administered by any
standard dosage and route of administration (see above).
Alternatively, gene therapy using an IAP expression
construct may be undertaken to reverse or prevent the
cell defect prior to the development of the degenerative
~o disease.
The methods of the instant invention may be used
to reduce or diagnose the disorders described herein in
any mammal, for example, humans, domestic pets, or
livestock. Where a non-human mammal is treated or
~s diagnosed, the IAP polypeptide, nucleic acid, or antibody
employed is preferably specific for that species.
Other Embodiments
In other embodiments, the invention includes any
protein which is substantially identical to a mammalian
zo IAP polypeptides (Figs. 1-6; SEQ ID NOs:l-42); such
homologs include other substantially pure naturally-
occurring mammalian IAP proteins as well as allelic
variants; natural mutants; induced mutants; DNA sequences
which encode proteins and also hybridize to the IAP DNA
z5 sequences of Figs. 1-6 (SEQ ID NOS:1-42) under high
stringency conditions or, less preferably, under low
stringency conditions (e. g., washing at 2X SSC at 400C
with a probe length of at least 40 nucleotides); and
proteins specifically bound by antisera directed to a IAP
so polypeptide. The term also includes chimeric
polypeptides that include a IAP portion.
The invention further includes analogs of any
naturally-occurring IAP polypeptide. Analogs can differ
from the naturally-occurring IAP protein by amino acid
CA 02403947 2002-10-21
sequence differences, by post-translational
modifications, or by both. Analogs of the invention will
generally exhibit at least 85%, more preferably 90%, and
most preferably 95% or even 99% identity with all or part
s of a naturally occurring IAP amino acid sequence. The
length of sequence comparison is at least 15 amino acid
residues, preferably at least 25 amino acid residues, and
more preferably more than 35 amino acid residues.
Modifications include in vivo and in vitro chemical
~o derivatization of polypeptides, e.g., acetylation,
carboxylation, phosphorylation, or glycosylation; such
modifications may occur during polypeptide synthesis or
processing or following treatment with isolated modifying
enzymes. Analogs can also differ from the naturally-
~s occurring IAP polypeptide by alterations in primary
sequence. These include genetic variants, both natural
and induced (for example, resulting from random
mutagenesis by irradiation or exposure to
ethanemethylsulfate or by site-specific mutagenesis as
zo described in Sambrook, Fritsch and Maniatis, Molecular
Cloning: A Laboratory Manual (2d ed.), CSH Press, 1989,
or Ausubel et al., supra). Also included are cyclized
peptides, molecules, and analogs which contain residues
other than L-amino acids, e.g., D-amino acids or non-
z5 naturally occurring or synthetic amino acids, e.g., B or
y amino acids. In addition to full-length polypeptides,
the invention also includes IAP polypeptide fragments.
As used herein, the term "fragment," means at least 20
contiguous amino acids, preferably at least 30 contiguous
3o amino acids, more preferably at least 50 contiguous amino
acids, and most preferably at least 60 to 80 or more
contiguous amino acids. Fragments of IAP polypeptides
can be generated by methods known to those skilled in the
art or may result from normal protein processing (e. g.,
3s removal of amino acids from the nascent polypeptide that
CA 02403947 2005-03-18
76962-52D(S)
are not required for biological activity or removal of
- amino acids by alternative mR:~IA splicing or alternative
protein processing events).
Preferable fragment: or analogs according to the
s invention are those which facilitate specific detection
of a IAP nucleic acid or amino acid sequence in a sample
to be diagnosed. Particularly useful IAP fragments for
this purpose include, without limitation, the amino acid
fragments shown in Table 2.
