Description
FIELD OF THE INVENTION
[0001] The present invention relates to the identification of genes and proteins
encoded thereof from yeast and fungi whose expression is modulated upon
programmed cell death and which genes, proteins or functional fragments and
equivalents thereof may be used as selective targets for drugs to treat
infections caused by or associated with yeast and fungi or for the treatment of
proliferative disorders or for the prevention of apoptosis in certain diseases.
BACKGROUND TO THE INVENTION
[0002] Invasive fungal infections (e.g. Candida spp., Aspergillus spp., Fusarium
spp., Zygomycetes spp.) (Walsh, 1992) have emerged during the past two decades
as important pathogens causing formidable morbidity and mortality in an
increasingly diverse and progressively expanding population of immunocompromised
patients. Those with the acquired immune deficiency syndrome (AIDS) constitute
the most rapidly growing group of patients at risk for life-threatening mycosis.
But fungal Infections have also increased in frequency in several populations of
other susceptible hosts, including very-low-birth-weight infants, cancer
patients receiving chemotherapy, organ transplant recipients, burn patients and
surgical patients with complications.
[0003] These fungal infections are not limited to humans and other mammals, but
are also important in plants where they can cause diseases or cause the
production of unwanted compounds (e.g. Fusarium spp., Aspergillus spp., Botritis
spp., Cladosporium spp.).
[0004] Although recent advances in antifungal chemotherapy have had an impact on
these mycoses, expanding populations of immunocompromised patients will require
newer approaches to antifungal therapy. The discovery of novel antifungal agents
is thus an essential element of any new antifungal therapy.
[0005] Classical approaches for identifying antifungal compounds have relied
almost exclusively on inhibition of fungal or yeast growth as an endpoint.
Libraries of natural products, semi-synthetic, or synthetic chemicals are
screened for their ability to kill or arrest growth of the target pathogen or a
related nonpathogenic model organism. These tests are cumbersome and provide no
information about a compound's mechanism of action. The promising lead compounds
that emerge from such screens must then be tested for possible host-toxicity and
detailed mechanism of action studies must subsequently be conducted to identify
the affected molecular target.
[0006] Cells from multicellular organisms can commit suicide in response to
specific signals or injury by an intrinsic program of cell death. Apoptosis is a
form of programmed cell death which leads to elimination of unnecessary or
damaged cells. Cells that are either unwanted or potentially harmful to the
organism undergo the apoptotic process and show events like cell shrinkage,
chromatin condensation, cytoplasmic condensation, digestion of nuclear DNA, loss
of mitochondrial membrane potential, plasma membrane blebbing and phagocytosis
of the cell debris (Schwartz, et al. 1993). The Bcl-2 family of proteins is
centrally involved in the control of the programmed cell death process (PCD).
Proteins of this group belong either to the inhibitors of cell death (Bcl-2,
Bcl-X.sub.L) or to the group of proteins promoting apoptosis (Bax, Bak) (Oltvai
and Korsmeyer 1994; Knudson and Korsmeyer 1997; Reed et al. 1998). The ability
of the Bcl-2 family of proteins to regulate life and death of a cell is
conserved across evolution. Finding of homologues of PCD regulatory genes in
plants and animals suggests the possibility that some functions involved in this
process may originally have evolved in unicellular organisms, before a divergent
development between the plant and the animal kingdom had happened (Apte et al.
1995).
[0007] Expression of the pro-apoptotic human or mouse Bax protein in
Saccharomyces cerevisiae did induce cell death in this budding yeast (Sato et
al. 1994; Greenhalf et al. 1996; Zha et al. 1996). It was initially described as
a process that resembled autophagy with dissolution of the internal organelles
and vacuolisation. The apoptotic features characteristic for multicellular
eucaryotic cells like morphological changes In nuclear shape and chromatin
condensation, were not observed in this yeast (Zha et al. 1996). It was
therefore suggested that Bax-induced cell death in S. cerevisiae is due to the
toxicity of the Bax protein itself, mediated by a hypothetical pore-formation
without any involvement of a death program (Muchmore et al. 1996).
[0008] Bax expression in the fission yeast Schizosaccharomyces pombe did in
contrast show some of the typical apoptotic changes like DNA fragmentation,
chromatin condensation, dissolution of the nuclear envelope and cytosolic
vacuolisation, suggesting the presence of the evolutionary conserved PCD pathway
in this unicellular eucaryote (Ink et al. 1997; Jurgensmeier et al. 1997). Since
it is very unlikely that species dependent differences in the toxicity of the
Bax protein are the reason for this observed difference between the two yeasts,
a bona fide cell death pathway may well be present in S. cerevisiae.
[0009] Recent findings of a yeast mutant in the cell division cycle gene CDC48
show a number of morphological and molecular features that are considered
typical indicators of apoptosis markers in metazoan cells: exposure of
phosphatidylserine on the outer leaflet of the cytoplasmic membrane, DNA
breakage as well as chromatin condensation and fragmentation, supporting the
existence of a basic PCD machinery in this unicellular yeast. This theory was
supported by the analysis of a wild type yeast cell expressing the human Bax
protein. Comprehensive tests for morphological markers of apoptosis did show a
series of changes, identical to morphological markers defining apoptosis (Ligr,
Madeo et al. 1998). Recent findings from the same group (Madeo et al., 1999)
implicate oxygen stress as a general regulator of apoptosis in yeast but the
actual mechanism of Bax lethality in S. cerevisiae remains unclear. It is an aim
of the present invention to provide new bax sequences for expression in yeast
and fungi and tools for identifying yeast and candida functions in the pathways
leading to programmed cell death.
[0010] It is an aim of the present invention to provide nucleic acids as well as
polypeptides which represent potential molecular targets for the identification
of new compounds which can be used in alleviating diseases or conditions
associated with yeast or fungal infections.
[0011] It is a further aim of the present invention to provide uses of these
nucleic acid and polypeptide molecules for treating diseases associated with
yeast or fungi or for the preparation of (a) medicament(s) for treating said
diseases.
[0012] It is also an aim of the invention to provide pharmaceutical compositions
and vaccines comprising these nucleic acids or polypeptides.
[0013] It is also an aim of the present invention to provide vectors comprising
these nucleic acids, as well as host cells transfected or transformed with said
vectors.
[0014] It is also an aim of the invention to provide antibodies against these
polypeptides, which can be used as such, or in a composition as a medicament for
treating diseases associated with yeast and fungi.
[0015] It is another aim of the invention to provide methods to selectively
identify compounds or polypeptides capable of inhibiting or activating
expression of the polypeptides of the invention or capable of selectively
modulating expression or functionality of such polypeptides. The nucleic acid
and polypeptide molecules alternatively can be incorporated into an assay or kit
to identify these compounds or polypeptides.
[0016] It is also an aim of the invention to provide methods for preventing
infection with yeast or fungi.
[0017] It is a further aim of the invention to provide human homologues for the
nucleic acids and polypeptides of the invention for use in treating
proliferative disorders, such as cancer, or for the prevention of apoptosis in
certain diseases, or for the preparation of a medicament for treating such
disorders or diseases.
[0018] All the aims of the present invention have been met by the embodiments as
set out below.
SUMMARY OF THE INVENTION
[0019] Since it has been discovered that the mammalian bax gene triggers
apoptotic changes in yeast (Ligr et al., 1998), this can be an indication that
the molecular pathways eventually leading to programmed cell death may also be
partially present in yeast cells and other unicellular eukaryotes.
Identification of genes involved in this process could be important for the
development of new antifungal therapeutics.
[0020] The present inventors overexpressed the Bax protein in the pathogenic
yeast Candida albicans and found that this leads to a similar phenotype. However
these results could only be received after having constructed a new synthetic
BAX gene which could be adequately expressed in this pathogenic organism.
[0021] Furthermore, the present inventors identified a range of specific nucleic
acids which are involved in the molecular pathways eventually leading to
programmed cell death. The present inventors were able to identify via macro
array screening a range of genes involved in a pathway eventually leading to
programmed cell death in the yeast Saccharomyces cerevisiae. Genes which were
differentially expressed (analysed using the Pathways.TM. software) at different
time points after Bax expression are envisaged as candidate genes in the present
invention.
[0022] Additionally, the invention also relates to Candida spp. homologues of
the S. cerevisiae candidate genes and their uses in stimulating or preventing
cell death in yeast and fungi, especially pathogenic yeast and fungi are
herewith envisaged.
[0023] Furthermore, also part of the invention are the human homologues of these
apoptosis-associated S. cerevisiae nucleic acids and polypeptides and their
potential use in treating proliferative disorders in human and other mammals.

[0030] (f) a nucleic acid encoding a functional fragment of any of the nucleic
acids as specified in a) to e); and
[0031] (g) the complement of any of the nucleic acids as specified in a) to f),
[0032] for the preparation of a medicament for treating diseases associated with
yeast or fungi. Sequence similarity searches were performed using the BLAST
software package version 2. Identity and similarity percentages were calculated
using BLOSUM62 as a scoring matrix. As known in the art, "similarity" between
two polypeptides is determined by comparing the amino acid sequence and its
conserved amino acid substitutes of one polypeptide to the sequence of a second
polypeptide. Moreover, also known in the art is "identity" which means the
degree of sequence relatedness between two polypeptide or two polynucleotide
sequences as determined by the identity of the match between two strings of such
sequences. Both identity and similarity can be readily calculated. While there
exist a number of methods to measure identity and similarity between two
polynucleotide or polypeptide sequences, the terms "identity" and "similarity"
are well known to skilled artisans (Carillo and Lipton, 1988). Methods commonly
employed to determine identity or similarity between two sequences include, but
are not limited to, those disclosed in "Guide to Huge Computers (Bishop, 1994)
and Carillo and Lipton (1988). Preferred methods to determine identity are
designed to give the largest match between the two sequences tested. Methods to
determine identity and similarity are codified in computer programs. Preferred
computer program methods to determine identity and similarity between two
sequences include, but are not limited to, GCG program package (Devereux et al.,
1984), BLASTP, BLASTN and FASTA (Altschul et al, 1990).
[0033] The expression functional fragment of a nucleic acid" as used herein
means the minimal nucleic acid which is necessary to encode a functional protein
(or polypeptide). For instance, in situations where a nucleic acid is provided
comprising at the 5' end and at the 3' end more nucleotides than the actual open
reading frame, the invention also relates to fragments of the nucleic acid which
are smaller but which still contain the workable open reading frame. Also meant
are parts of the open reading frame encoding a polypeptide having the same
properties as the polypeptide encoded by the complete open reading frame.
[0034] The expression "a pathway eventually leading to programmed cell death"
refers to a sequence of steps ultimately leading to cell death and which can be
triggered at various steps in this pathway by various agents, such as Bax, Bak,
CED4, hydrogen peroxide, diamide and farnesol. The nucleic acid sequences to be
used according to this aspect of the invention from Saccharomyces cerevisiae are

[0035] The yeast or fungi according to the invention may be, but are not
restricted to, pathogenic yeast or fungi. As such, yeast or fungi may cause
infections in healthy individuals as well as in immunocompromised patients.
[0036] The expression "treating diseases associated with yeast and fungi" not
only refers to diseases or infections caused by said organisms but also refers
to allergic reactions caused by said organisms, such as the so-called
"professional diseases" in, for instance, bakery and brewery and that are caused
by yeast or fungi which are commonly known as "non-pathogenic". Some examples of
specific diseases associated with yeast or fungi are further exemplified.

[0048] Therefore, according to a further preferred embodiment, the invention
relates to an isolated nucleic acid from mammal or human origin which nucleic
acid sequence is selected from:
[0049] (a) a nucleic acid encoding a protein having an amino acid sequence as
represented in any of SEQ ID NOs 676, 678, 680, 682, 684 and 686, or encoding a
functional equivalent, derivative or bioprecursor of said protein;
[0050] (b) a nucleic acid encoding a protein having an amino acid sequence which
is more than 70% similar, preferably more than 75% or 80% similar, more
preferably more than 85%, 90% or 95% similar and most preferably more than 97%
similar to any of the amino acid sequences as represented by any of SEQ ID NOs
676, 678, 680, 682, 684 and 686;
[0051] (c) a nucleic acid encoding a protein having an amino acid sequence which
is more than 70% identical, preferably more than 75% or 80% identical, more
preferably more than 85%, 90% or 95% identical and most preferably more than 97%
identical to any of the amino acid sequences as represented by any of SEQ ID NOs
676, 678, 680, 682, 684 and 686;
[0052] (d) a nucleic acid comprising a sequence as represented in any of SEQ ID
NOs 675, 677, 679, 681, 683 and 685;
[0053] (e) a nucleic acid which is more than 70% identical, preferably more than
75 or 80% identical, more preferably more than 85%, or 90% or 95% identical and
most preferably more than 97% identical to any of the nucleic acid sequences as
represented by any of SEQ ID NOs 675, 677, 679, 681, 683 and 685;
[0054] (f) a nucleic acid encoding a functional fragment of any of the nucleic
acids as specified in a) to e); and
[0055] (g) the complement of any of the nucleic acids as specified in a) to f),
[0056] for the preparation of a medicament for treating diseases associated with
yeast or fungi.
[0057] The invention also relates to the use of said nucleic acids for treating
and/or preventing and/or alleviating proliferative disorders or for the
prevention of apoptosis in certain disorders or diseases.
[0058] The expression "proliferative disorders" or "proliferative diseases"
refers to an abnormality within a patient or animal such as cancer. Normal cells
start to proliferate due to a change in the coding or non-coding sequence of the
DNA resulting in a swollen or distended tissue. Mutation may arise without
obvious cause. An abnormal benign or malignant mass of tissue is formed that is
not inflammatory. Cells of pre-existent tissue start to divide unexpectedly and
resulting cell mass possesses no physiologic function.
[0059] The expression "apoptosis" or "apoptosis-related diseases" includes
diseases such as autoimmunity diseases, ischemia, diseases related with viral
infections or neurodegenerations.
[0060] It should be clear that the invention also relates to all nucleic acids
according to the invention and which are specifically described above, and which
can be DNA, cDNA, genomic DNA, synthetic DNA, or RNA wherein T is replaced by U.
A nucleic acid according to the invention may also comprise any modified
nucleotide known in the art.
[0061] The term "nucleic acid sequence" also includes the complementary sequence
to any single stranded sequence given.
[0062] According to the invention, these sequences and their homologues in other
yeast and fungi or in human or other mammals as well as the polypeptides which
they encode represent novel molecular targets which can be incorporated into an
assay to selectively identify compounds capable of inhibiting or activating
expression of such polypeptides. Furthermore, the invention also relates to the
potential use of said sequences in alleviating diseases or conditions associated
with yeast or fungi infections, such as diseases caused by Candida spp.,
Aspergillus spp., Microsporum spp., Trichophyton spp., Fusarium spp.,
Zygomycetes spp., Botritis spp., Cladosporium spp., Malassezia spp.,
Epidermophyton floccosum, Blastomyces dermatitidis, Coccidioides immitis,
Histoplasma capsulatum, Paracoccidioides brasiliensis, Cryptococcus neoformans,
and Sporothrix schenckii, such as, but not limited to:
[0063] Candidiasis, caused by C. albicans and other members of the genus
Candida, which are primary or secondary mycotic infections, also named
candidosis, moniliasis and thrush;
[0064] Aspergilliosis, caused by members of the genus Aspergillus, form a
spectrum of diseases;
[0065] Histoplasmosis, caused by Histoplasma capsulatum, which is a pulmonary
disease always seen in HIV positive or other immunocompromised individuals;
[0066] Paracoccidioidomycosis, caused by Paracoccidioides brasiliensis, which is
a granulomatous disease that originates as a pulmonary disease;
[0067] Blastomycosis, caused by Blastomyces dermatitidis, which may be a benign
and self-limiting infection or a chronic granulomatous and suppurative mycosis,
also named Chicago disease or Gilchrist's disease;
[0068] Coccidioidomycosis, caused by Coccidioides imminitis, and which is a
respiratory infection that typically resolves rapidly, but the mycosis can
become acute, chronic, severe or fatal; also named San Joaquin Valley fever or
Valley fever;
[0069] Cryptococcosis, caused by Cryptococcus neoformans, which is a chronic,
subacute to acute pulmonary, systemic or meningitic disease, also named
Torulosis;
[0070] Sporotrichosis, caused by Sporothrix schenckii, which is a chronic
infection characterized by nodular lesions of cutaneous or subcutaneous tissues
and adjacent lymphatics that suppurate, ulcerate and drain.
[0071] Some of the pathways leading to apoptosis are conserved between mammalian
cells and yeast or fungi. Therefore the invention also relates to the potential
use of homologous sequences from human or mammalian origin for preventing and/or
alleviating diseases or conditions where apoptosis or non-apoptosis of cells is
impaired, for instance in proliferative disorders. In this respect also cancer
can be seen as a proliferative disorder. Furthermore, targets which are part of
such a conserved pathway may be used to stimulate or inhibit the apoptosis in
mammalian cells. E.g. stimulation of apoptosis is desirable in the treatment of
tumor cells/tissues.
[0072] Human homologues according to the invention can be obtained by selective
hybridisation of the yeast and candida nucleic acid molecules of the invention
against human genome or cDNA libraries according to methods well known in the
art (Sambrook et al., 1989). Human polypeptide homologues are obtained from the
corresponding human nucleic acid homologous nucleotide sequences.
[0073] The present invention further relates to a nucleic acid capable of
selectively hybridising to at least one of the nucleic acid molecules according
to the invention, or the complement thereof.
[0074] The term "selectively hybridising" or "specifically hybridising" means
hybridising under conditions wherein sequences can be detected which are
homologues of the sequences of the invention, but which are for instance derived
from heterologous cells or organisms, and wherein said sequences do not
hybridize with known sequences. In a preferred embodiment, mammalian homologues
can be detected. It is well known to the person skilled in the art which methods
for hybridisation can be used and which conditions are necessary for selectively
or specifically hybridising. Preferably, hybridization under high stringency
conditions can be applied (Sambrook et al., 1989).
[0075] As such, the present invention also relates to the use of the nucleic
acid sequences of the invention for detecting homologues in heterologous
organisms including but not limited to mammalian organisms.
[0076] The invention also relates to an isolated nucleic acid comprising a human
homologue of at least one of the yeast or candida nucleic acids described
earlier. The invention also relates to a polypeptide encodable by said human
homologue of said nucleic acid.
[0077] In a further embodiment the invention also relates to an expression
vector comprising a human homologue of at least one of the yeast or candida
nucleic acids described herein. Said expression vector according can be an
expression vector wherein said nucleic acid sequence is operably linked to one
or more control sequences allowing the expression in prokaryotic and/or
eukaryotic host cells. According to a further embodiment, the expression vector
comprises an inducible promoter and/or a reporter molecule.
[0078] The invention also relates to a host cell transformed, transfected or
infected with any of the above described vectors.
[0079] According to a preferred embodiment, the invention relates to an
antisense version of any of the nucleic acids of the invention and described
above.
[0080] The present invention more particularly relates to an antisense molecule
comprising a nucleic acid capable of selectively hybridising to at least one of
the nucleic acids of the invention. In an interesting embodiment the invention
relates to a nucleic acid capable of selectively hybridising to a human
homologue of at least one yeast or candida nucleic acid described herein.
[0081] Polynucleotides according to the invention may be inserted into vectors
in an antisense orientation in order to provide for the production of antisense
RNA. Antisense RNA or other antisense nucleic acids may also be produced by
synthetic means.
[0082] The present invention also advantageously provides nucleic acid molecules
of at least approximately 10 contiguous nucleotides of a nucleic acid according
to the invention and preferably from 10 to 50 nucleotides. These sequences may,
advantageously be used as probes or primers to initiate replication, or the
like. Such nucleic acid sequences may be produced according to techniques well
known in the art, such as by recombinant or synthetic means. The probes will
hybridise specifically with any of the nucleic acid molecules of the invention.
The primers will specifically amplify any of the nucleic acid molecules of the
invention. The probes or primers according to the invention may also be used in
diagnostic kits or the like for detecting the presence of a nucleic acid
according to the invention. These tests generally comprise contacting the probe
with the sample under hybridising conditions and detecting the presence of any
duplex or triplex formation between the probe and any nucleic acid in the
sample.
[0083] According to the present invention these probes may be anchored to a
solid support. Preferably, they are present on an array so that multiple probes
can simultaneously hybridize to a single biological sample. The probes can be
spotted onto the array or synthesized in situ on the array. (Lockhart et al.,
1996). A single array can contain more than 100, 500 or even 1,000 different
probes in discrete locations. Such arrays can be used to screen for compounds
interacting with said probes.
[0084] Advantageously, the nucleic acid sequences, according to the invention
may be produced using recombinant or synthetic means, such as for example using
PCR cloning mechanisms which generally involve making a pair of primers, which
may be from approximately 10 to 50 nucleotides to a region of the gene which is
desired to be cloned, bringing the primers into contact with mRNA, cDNA, or
genomic DNA from the yeast or fungal cell, performing a polymerase chain
reaction under conditions which bring about amplification of the desired region,
isolating the amplified region or fragment and recovering the amplified DNA.
Generally, such techniques as defined herein are well known in the art, such as
described in Sambrook et al. (1989). These techniques can be used to clone
homologues of the nucleic acid sequences of the invention in other organisms.
[0085] The nucleic acids or oligonucleotides according to the invention may
carry a revealing label. Suitable labels include radioisotopes such as .sup.32P,
.sup.33P or .sup.35S, enzyme labels or other protein labels such as biotin or
fluorescent markers. Such labels may be added to the nucleic acids or
oligonucleotides of the invention and may be detected using techniques known in
the art.
[0086] According to another embodiment of the invention, the nucleic acid
sequences according to the invention as defined above may, advantageously, be
included in a suitable vector, preferably an expression vector which may be
transformed, transfected or infected into a host cell. In such an expression
vector the nucleic acid is operably linked to one or more control sequences
allowing the expresssison in host cells, such as a suitable promotor, or the
like, to ensure expression of the proteins according to the invention in a
suitable prokaryotic or eukaryotic host cell. Said promoter may be either
constitutive, inducible or cell- or tissue- or organ-specific. The expression
vector may advantageously be a plasmid, cosmid, virus or other suitable vector
which is known to those skilled in the art. The expression vector and the host
cell defined herein also form part of the present invention. Said host cell can
be from bacterial, yeast, fungal, insect, mammal or human origin, or any other
host wherein said vector can be introduced by at least one of the methods known
in the art. However, preferred host cells are lower eukaryotic cells such as a
yeast cell or a fungal cell. Yeast and fungal cells are particularly
advantageous because they provide the necessary post-translational modifications
to the expressed proteins of the invention, similar to those of the natural
proteins from which they are derived. These modifications confer optimal
conformation of said proteins, which when isolated may advantageously be used in
kits, methods or the like.
[0087] In a further embodiment, the expression vector may further comprise an
inducible promoter, and/or further a reporter molecule.
[0088] The invention further relates to any one of the nucleic acids as defined
above for use as a medicament.
[0089] Nucleotide sequences according to the invention are particularly
advantageous for providing selective therapeutic targets for treating yeast or
fungi-associated infections. For example, an antisense nucleic acid capable of
binding to the nucleic acid sequences according to the invention may be used to
selectively inhibit expression of the corresponding polypeptides, leading to
impaired growth or death of yeast and fungi with reductions of associated
illnesses or diseases.
[0090] Also envisaged in the present invention are promoter or other control
sequences that are comprised within the nucleic acids of the invention, said
nucleic acid control sequences can also serve as a target for the identification
of compounds or proteins which interfere with the control of expression of
downstream encoded polypeptides.
[0091] Furthermore, also the human homologues of the yeast and candida nucleic
acids may be useful in diseases where apoptosis of cells plays a substantial
role, both in situations where apoptosis of (particular) cells is wanted or
unwanted.
[0092] The invention thus also relates to the use of any of the nucleic acids of
the invention or to a human homologue thereof for treating proliferative
disorders or for the prevention of apoptosis in certain disorders or diseases.
As described above, the invention also relates to the use of antisense molecules
of the nucleic acids of the invention or to an antisense of any of the human
homologues for treating proliferative disorders or for the prevention of
apoptosis in certain disorders or diseases.
[0093] Said nucleic acids, human homologues and antisense molecules can also be
used for the preparation of a medicament for treating or preventing the
above-mentioned diseases.
[0094] According to yet another embodiment, the invention relates to at least
one polypeptide encodable by a nucleic acid of the invention.
[0095] The invention also relates to the use of a polypeptide which is involved
in a pathway eventually leading to programmed cell death of yeast or fungi, said
polypeptide being selected from:
[0096] (a) a protein having an amino acid sequence as represented in any of SEQ
ID NOs 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52,

[0099] (d) a functional fragment of any of said proteins as defined in a) to c),
[0100] for the preparation of a medicament for treating diseases associated with
yeast or fungi.
[0101] The term "functional fragment" of a protein means a truncated version of
the original protein or polypeptide referred to. The truncated protein sequence
can vary widely in length; the minimum size being a sequence of sufficient size
to provide a sequence with at least a comparable function and/or activity of the
original sequence referred to, while the maximum size is not critical. In some
applications, the maximum size usually is not substantially greater than that
required to provide the desired activity and/or function(s) of the original
sequence. A functional fragment can also relate to a subunit with similar
function as said protein. Typically, the truncated amino acid sequence will
range from about 5 to about 60 amino acids in length. More typically, however,
the sequence will be a maximum of about 50 amino acids in length, preferably a
maximum of about 60 amino acids. It is usually desirable to select sequences of
at least about 10, 12 or 15 amino acids.
[0102] Functional fragments include those comprising an epitope which is
specific or unique for the proteins according to the invention. Epitopes may be
determined using, for example, peptide scanning techniques as described in
Geysen et al. (1986). Preferred functional fragments have a length of at least,
for example, 5, 10, 25, 50, 75, 100, 125, 150, 175 or 200 amino acids.

[0109] According to a further preferred embodiment, the present invention
relates to an isolated polypeptide which is involved in a pathway for programmed
cell death of mammalian cells selected from:
[0110] (a) a polypeptide having an amino acid sequence as represented in any of
SEQ ID NOs 676, 678, 680, 682, 684 and 686, or encoding a functional equivalent,
derivative or bioprecursor of said protein;
[0111] (b) a polypeptide having an amino acid sequence which is more than 70%
similar, preferably more than 75% or 80% similar, more preferably more than 85%,
90% or 95% similar and most preferably more than 97% similar to any of the amino
acid sequences as represented by any of SEQ ID NOs human 676, 678, 680, 682, 684
and 686;
[0112] (c) a polypeptide having an amino acid sequence which is more than 70%
identical, preferably more than 75% or 80% identical, more preferably more than
85%, 90% or 95% identical and most preferably more than 97% identical to any of
the amino acid sequences as represented by any of SEQ ID NOs 676, 678, 680, 682,
684 and 686; and,
[0113] (d) a functional fragment of any of said polypeptides as defined in a) to
c).
[0114] The invention also relates to the polypeptides of the invention and
described above for use as a medicament.
[0115] Pharmaceutical or fungicidal compositions comprising at least one of the
nucleic acids, antisense molecules, polypeptides of the invention optionally
together with a pharmaceutically acceptable carrier, diluent or excipient
therefor, are also part of the invention.
[0116] The polypeptides described above or the human or mammal homologues
thereof can also be used for treating proliferative disorders or for the
prevention of apoptosis in certain diseases.
[0117] The invention furthermore relates to a pharmaceutical composition for use
as a medicament for treating proliferative disorders or for the prevention of
apoptosis in certain diseases comprising a nucleic acid molecule of the
invention or a human homologue thereof, an antisense molecule to at least one of
the nucleic acids of the invention or an antisense molecule to a mammalian
homologue of said nucleic acid or a polypeptide of the invention or a human
homologue thereof together with a pharmaceutically acceptable carrier, diluent
or excipient therefor.
[0118] The polypeptide or protein according to the invention may also include
variants of any of the polypeptides of the invention as specified above having
conservative amino acid changes.
[0119] The present invention also relates to a vaccine for immunizing a mammal
comprising at least one (recombinant) nucleic acid molecule or at least one
(recombinant) polypeptide of the invention in a pharmaceutically acceptable
carrier. Preferred vaccines are those that can be used for immunization against
infections caused by yeast and fungi. Other preferred vaccines can be used for
immunizing mammals against proliferative disorders or for preventing apoptosis
in certain diseases.
[0120] Pharmaceutically acceptable carriers include any carrier that does not
itself induce the production of antibodies harmful to the individual receiving
the composition. Suitable carriers are typically large, slowly metabolizing
macromolecules such as proteins, polysaccharides, polylactic acids, polyglycolic
acids, polymeric amino acids, amino acid copolymers; and inactive virus
particles. Such carriers are well known to those of ordinary skill in the art.
[0121] A "vaccine" is an immunogenic composition capable of eliciting protection
against infections caused by yeast or fungi, whether partial or complete.
[0122] Said vaccine compositions may include prophylactic as well as therapeutic
vaccine compositions. When a vaccine is used for protecting individuals against
certain infections or diseases, it is called a prophylactic vaccine. A vaccine
may also be useful for treatment of an individual, in which case it is called a
therapeutic vaccine.
[0123] The term "therapeutic" refers to a composition capable of treating
infections caused by yeast or fungi or capable of treating proliferative
disorders.
[0124] Also encompassed within the present invention are antibodies, monoclonal
or polyclonal, capable of specifically binding to one or more epitopes of the
polypeptides or proteins of the invention. The polypeptides of the invention are

[0125] The term "specific binding" implies that there is substantially no
cross-reaction of the antibody with other proteins.
[0126] The antibodies according to the invention may be produced according to
techniques which are known to those skilled in the art. Monoclonal antibodies
may be prepared using conventional hybridoma technology as described by Kohler
and Milstein (1979). Polyclonal antibodies may also be prepared using
conventional technology well known to those skilled in the art, and which
comprises inoculating a host animal, such as a mouse, with a protein or epitope
according to the invention and recovering the immune serum. The present
invention also includes fragments of whole antibodies which maintain their
binding activity, such as for example, Fv, F(ab') and F(ab').sub.2 fragments as
well as single chain antibodies.
[0127] The antibodies of the invention are capable of specifically binding to at
least one of the yeast or candida polypeptides as defined earlier or to a human
homologue thereof or to a specific epito
