Since prostate cancer (Pca) is a heterogeneous di
sease, it becomes clear that a defined set of markers will
become important for early diagnosis, monitoring and
prognosis of Pca. Polyamines (PAs) (putrescine (Put),
spermidine (Spd) and spermine (Spm)) which play a
significant role in the regulation of growth and develop
ment of different cell types [1–3] are among potential
biomarkers. Elevated PAs levels are not specific for
Pca only, but they are good indicators for monitoring
of the disease and may serve as biomarkers for rapidly
proliferating cells. PA content is regulated by many
events such as biosynthesis and catabolic processes,
genetic control of key enzymes at transcriptional and
translational stage, regular diet. The induction of PA
synthesis by any stimulus results in increased rate of
DNA, RNA and protein synthesis [1–6].
Ornithine decarboxylase (ODC) is a key enzyme
that catalyzes the conversion of ornithine to Put. Then
Put is converted to Spd and Spm by Spdsynthetase
and Spmsynthetase respectively [1, 2, 7, 8]. PAs are
very important cationic molecules for cell homeostasis.
If an excess amount of PA is accumulated in the cells,
these molecules undergo oxidation in peroxisomes
with involvement of monoamine oxidases, in particular
PA oxidase (PAO). Oxidation of Spd and Spm occur
only after N1acetylation by spermidine/spermine
N1acetyltransferase (SSAT) present in cytoplasm [8,
10, 11]. PAs may be degraded also by diamine oxidase
(DAO), a copper/quinone containing serum amine
oxidase. This enzyme is generally responsible for the
cytotoxicity of PAs in in vitro models in the presence of
fetal calf serum, but its physiological role is not clearly
understood [12, 13]. Arginase catalyzes the oxidation
of PAs such as Spm and Spd, to much less active
compound called Put (Fig. 1) [14].
The content of PAs depends on two main sources:
external (consumptiondependent PAs or usage of
deposit PA from red blood cells) and synthesis that is
regulated by ODC under the control of c-Myc gene [1,
9]. The excess amounts of PAs are excreted via efflux
mechanism after conversion to N1acetylspermine
and N1acetylspermidine. PAs may affect cell death
by modulating the release of cytochrome c from
mitochondria, which triggers activation of caspases
and induction of apoptosis. PAs may also affect signal
transduction pathways mediated by the nuclear tran
scription factorB (NFkB), mitogen activated protein
kinase (MAPK) family members and, possibly, other
kinases which modulate the expression of genes impli
cated in the control of cell growth and cell death. The
proposed hypothesis postulates that NFkB may modu
late both growth and death mechanisms using PPARγ
and polyamine response element (PRE). ODC plays
the central role in this network, quickly transforming
external signals (growth promoting stimuli, hormones,
drugs, growth factors, mitogens) in biological activity.
The data demonstrated that overexpression of ODC
leads to transformation of cells [15–19].
ODC expression is controlled at the transcriptional,
translational and posttranslational level [20]. ODC
degradation is regulated by regulatory enzyme called
antizyme (AZ) that is induced by PAmediated shifting
of translational frame [21]. AZ binds to ODC monomers
and stimulates their proteolytic degradation in proteo
somes. AZ also downregulates PA’s uptake by cells.
In turn, activity of AZ is regulated by special inhibitor
homologous to ODC [22].
Despite numerous studies, the specific role of
the ODCPA system in cellular physiology is still not
clarified yet.
Role of Polyamines in Cell GRowth
and diffeRentiation
PAs are able to bind to macromolecules such as
nucleic acids, proteins and phospholipids at physio
logical pH. Consequently, it has been suggested that
PAs are necessary for stabilization of these molecules.

of DNA and induce BZ and BA transitions in certain
DNA sequences. PADNA interaction and resultant
structural changes in DNA may provide the molecular
basis by which PAs regulate cell proliferation. It was
proposed that major function of cationic PAs in the
process of cell division may be the stabilization of rep
lication complexes between DNA and nuclear matrix,
condensation and packaging of newly synthesized
DNA into nucleosomes and chromatin [23–25]. PAs
are also involved in stabilization of RNA [26–28], in
protein synthesis and endogenous modification of
NMDA receptor ion channel and voltagedependent
Ca+2 and K+ channels [29, 30].
PAs are involved in cell proliferation, embryonic
development, cell cycle. PA biosynthesis deficient
mutant cells do not grow if PAs are added to the culture
medium. Generally, resting cells contain low levels of
PAs but if these cells are stimulated to divide by trophic
factors, PAs levels increase. PA reduction causes an
aberrated cell cycle progression and accumulation of
cells in one of phases of cell cycle [31]. Inhibition of
PA biosynthesis also affects cell cycle related features
such as DNA sensitivity to DNAses [23]. Benign pros
tate hyperplasia (BPH) is very frequent age dependent
illness in men. According to Liu et al. [32] the increased
ODC activity and PA content in prostate tissue may
correlate with the pathogenesis of BPH. The high
level of ODC activity is induced by overexpression of
ODC mRNA. The contents of Put, Spd, and Spm in
BPH tissues were 2.2, 3.4, and 6.0 times higher than
those in normal tissues, respectively; ODC activity of
BPH tissue was 3.2 times higher than in normal tissue.
The expression level of ODC mRNA in BPH tissues was
higher than that in normal tissues.
PAs also affect cell differentiation. Janne et al. [33]
suggested that decrease of Spd/Spm ratio reflects
transition from proliferation into differentiation state.
Role of Polyamines in aPoPtosis
The number of cells in adult human body is steady
due the balance between cell proliferation and cell
loss. Controlled cell death is known as apoptosis or
programmed cell death. Apoptosis include oligonu
cleosomal DNA degradation, condensation of cyto
plasm and nuclei and formation of apoptotic bodies.
Changes in PA homeostasis (elevated PA accu
mulation) may lead to apoptosis. Moreover, induction
of ODC is an early event in the induction of apoptosis
[35]. Involvement of ODC in the process of cell death
becomes apparent from researches on neuronal cell
figure. The amount of PAs has two sources inside the cell. One of them is external PAs sources such as absorption from diet or
usage of deposit PA from red blood cells or synthesis. PA synthesis is regulated by ODC under the control of cMyc. The excess
amount of PAs is excreted via efflux mechanism after conversion with N1acetylespermine and N1acetylspermidine. Their involve
ment in signal transduction network is under control of cellular death and growth balance. PA may affect cell death by modulating
the release of cytochrome c from mitochondria, which triggers the activation of caspases and the induction of apoptosis. PAs may
also affect signal transduction pathways mediated by the nuclear transcription factorB (NFkB), mitogen activated protein kinase
(MAPK) family members and, perhaps, other kinases which modulate the expression of genes implicated in the control of cell growth
and cell death. The proposed hypothesis is NFkB may modulate both growth and death mechanism using PPARγ and polyamine
response element (PRE) and has dual effect. However, the manager molecule in this network is determined as ODC because of
cMyc relationship
180 Experimental Oncology 28, 178–186, 2006 (September)
death induced by hypoglycemia, neurotoxic agents
and traumatic brain injury [36]. These studies revealed
a significant increase in ODC gene expression, protein
synthesis and Put levels. Numerous studies in different
cell systems have shown pronounced elevation of ODC
activity after induction of apoptosis [35]. The role of
ODC in apoptosis was studied by Packham and Cleve
land [37, 38] who showed that ODC is an important
mediator of cmycinduced apoptosis, and suppose
that cmyc induces ODCmediated apoptosis and
proliferation by different but overlapping pathways.
Both upregulation and downregulation of PA
levels may be associated with apoptotic events. For
example, treatment of HL60 cells with etoposide,
a classic inducer of apoptosis, resulted in early and
transient increase of ODC content, which may initiate
apoptosis, followed by its decrease, which would
sustain this process [40]. ODC induction and Spd ac
cumulation have been related to the progression of the
cell cycle until a checkpoint from which apoptosis is
triggered in the presence of cell deathinducing signals
or negative growth factors [35, 41].
The involvement of PAs in apoptosisrelated path
ways at the level of mitochondria has been investigated
in different cell models. Some research groups have
initially studied the effects of PAs on events directly
related to the activation of the caspases. PAs, par
ticularly Spm, can trigger the activation of caspases
in cellfree models of apoptosis and PAs can directly
induce the release of cytochrome c from mitochondria
and activate the death program [42].
The release of cytochrome c from mitochondria
may be modulated by Bcl2 family proteins (Bax and
Bid), which influence opening of mitochondrial perme
ability transition pores and the subsequent release of
cytochrome c into cytosol [43]. In intestinal cell line, PA
depletion antagonizes camptothecininduced apop
tosis by preventing translocation of the proapoptotic
Bcl2 family member Bax to mitochondria and inhibi
ting the release of cytochrome c [44]. Moreover, in
ODCoverproducing murine myeloma cells, accumula
tion of Put provokes apoptotic death that is inhibited by
DFMO and involves the release of cytochrome c from
mitochondria, followed by the activation of caspase
cascades [45]. On the other hand, in various lymphoid
cell lines, the complete depletion of PAs provoked
by the combined use of ODC and SAMDC inhibitors
causes the disruption of the mitochondrial membrane
potential, resulting in caspase activation and apoptotic
cell death [46]. A recent study [47] has shown that Spm
inhibits the release of cytochrome c from mitochondria
of the dexamethasonetreated thymocytes, but it does
not totally prevent the dexamethasoneinduced DNA
fragmentation.

The increasing awareness of the role of PAs in
cell behavior has attracted the attention to the PA as
biomarkers and potential targets in the treatment of
cancer and other diseases. In vitro and in vivo studies
have revealed that ODC activity and PAs metabolism
are fundamental for malignant transformation of
cells [15, 17–19]. In prostate adenocarcinoma, acute
lymphoblastic leukemia and brain tumors PAs and
their metabolic enzymes appear to be of diagnostic
value. Spermidine/spermine N1acetyltransferase
(SSAT) was shown to serve as a reliable biochemical
marker for proliferation of bladder epithelium [48, 49].
Recently PAs content was found to be a promising
biomarker for cervical malignancies [50].
Since PAs play important role in tumor cell growth,
interference in PA metabolism provides a possible
mean for chemotherapy of cancer. Different com
pounds inhibiting the activity of enzymes related to PA
metabolism have been described and their anticancer
properties have been analyzed [51–53]. However,
these compounds are active only in vitro, but not
in vivo. The reasons of the failure were determined as
follow: 1) rapid turnover of PA biosynthetic enzymes;
2) compensatory elevation of other PArelated en
zymes not targeted by inhibitor; 3) compensatory
increase of external uptake of PA; 4) compensatory
retroconversion of intracellular PA pool, because single
inhibitor cannot reduce all PA pools.
In recent years it has become obvious that struc
tural analogues of PAs can act as antineoplastic
agents. PA analogues downregulate the enzymes of
biosynthesis, deplete the PA pools and therefore inhibit
cell growth. So far, the most effective for cell growth
inhibition are PA analogues bis(ethyl)analogues of
Spm and bis(ethyl)analogues of Spd [54, 55]. Growth
inhibitory effects of these analogues have been estab
lished in a number of transformed cell lines [52], and
inhibition of ODC and SAMDC activities, depletion of
the PA pools and increase of SSAT activity upon their
action have been established. Currently, some of the
structural analogues of PAs are under Phase I or II of
clinical trials and show promising results.
Although the findings are based on an artificial
system (i.e. conditional overexpression of SSAT), there
are many pharmacological examples of SSAT induc
tion by the classes of drugs other than PA analogues
[56]. Anticancer drugs unrelated to PAs can also elicit
the significant increase of expression of SSAT gene.
Using cDNA gene profiling, Maxwell et al. [57] have
found that in MCF7 cells treated with 5fluorouracil,
SSAT gene expression is affected at the highest degree
among > 3000 genes studied. Similar results were ob
tained if the DNAalkylating platinum compounds, oxa
liplatin and cisplatin were applied [58]. Finally, SSAT
transgenic mice that are genetically predisposed to
develop prostate cancer (i. e. TRAMP mice) markedly
suppressed genitourinary tumors [59]. These findings
support the possibility that selective small molecule
inducers of SSAT may have therapeutic and/or preven
tive potential against prostate cancer.
In many developed countries, Pca is the second
leading cause of cancer related death among men.
Experimental Oncology 28, 178–186, 2006 (September) 181
Radical surgery and radiotherapy are curative options
for Pca. Early diagnosis is pivotal to prolonged survival
and quality of life. Prostate specific antigen (PSA)
is the first widespread accepted biomarker for Pca.
However it’s use has many limitations: overdiagnosis
of clinically insignificant Pca will cause overtreatment,
including incontinence, impotence that are side effects
of radical surgery and radiotherapy, and will negatively
affect the patients’ quality of life; from other hand, PSA
screening fails to detect a small proportion of highly
aggressive Pca. Therefore new Pca biomarkers need
to be discovered [60].
The considerable number of patients is diagnosed
at a time when the disease already is widespreaded.
These patients ultimately require androgen ablation
therapy that means surgical or medical castration.
Androgen ablation induces an apoptosis in the andro
gendependent Pca cells [61], but it’s hardly ever
curative [62]. The main reason for the failure of andro
gen ablation is heterogeneity of Pca cells population.
Compounds active against androgenindependent
Pca cells are required.
Prostate tissue is characterized by the highest
concentrations of PAs. In rats, the content of PAs is
the highest in ventral, dorsal and lateral prostate, but
lower in coagulating glands and seminal vesicles [63],
and Spd is the dominant PA. In human body, ODC was
found in prostate fluid, seminal plasma and sperm [64,
65], and Spm is the dominant PA in prostate tissue.
It was shown that prostate PAs content is under the
control of androgens [63, 66, 67]. Upon castration
induced apoptosis of prostate epithelial cells, ODC
activity and PA levels decrease significantly, but SSAT
activity increases [35]. Regeneration of prostate tis
sue by androgens support correlates with a marked
increase of ODC activity and PAs level. It was reported
that ODC activity and ODC mRNA level are stimulated
by androgens treatment, and ODC activity is especially
high in the epithelial cells of the prostate [66]. In vitro
studies [68, 69] have revealed that androgen regula
tion of ODC is directly related to androgen receptor.
Inhibition of ODC activity by difluoromethylornithine
(DFMO) reduces the development of prostate and
retards testosteroneinduced regrowth of prostate in
castrated rats [70].
It is clear now that in prostate tissue ODC and PAs
are involved in cell proliferation and secretory activi
ties via an androgenregulated Spmbinding protein
[71, 72].
Functional importance of seminal PAs is not clear
still. Spm molecules are localized in the middle and top
parts of the acrosome and possibly alter sperm fertili
zation competence and the acrosome reaction [73]. In
sperm cells Spm may originate from endogenous PA
biosynthesis, because ODC activity is associated with
spermatogenesis [74]. Seminal PAs may also regulate
seminal clotting or prevention of bacterial growth in
urinary tract [75].
Monitoring of PAs and ODC content in prostate tis
sue may be useful for the diagnosis and prognosis of
prostate cancer. Researches on rat prostate derived
tumor cell lines demonstrated that ODC activity was
elevated in quickly growing cells [76]. Similar data were
obtained on human prostate cancer cell lines (PC3,
TSUprl, DU145 and JCA1) [35]. Malignant PC3 and
TSUprl prostate cell lines possess the high level of
PAs associated with high ODC and low SSAT activities
[35]. Moreover, significantly elevated ODC expression
on mRNA and protein level in tumor tissue compared
to the benign tissue of prostate was revealed [65, 77].
Graaf et al. [78] have shown correlation between Spm
level and degree of differentiation in prostate tumors,
and indicated that normal and benign hyperplasic
prostate tissues have high content of Spm whereas
in tissue of prostate carcinoma with metastases Spm
levels are reduced.
PAs or their acetylated forms are secreted by
cells, and these circulating molecules can be reused
by PArequiring cells. Moulinoux et al. [79] revealed
that circulating Spd and Spm are transported by red
blood cells (RBC), and RBC PA level correlates with
tumor development in tumorgraft model. Analysis of
PAs levels in Pca cell lines with different degrees of
differentiation has shown that lessdifferentiated cell
lines contained lower Spm concentrations. Similar
correlation between Spm levels and the degree of
differentiation of prostate tumors was established by
Shipper et al. [35] in the study of biopsy materials.
These authors also indicated that in normal and be
nign hyperplastic prostate tissues a high content of
Spm occurs, whereas in tumor tissue, especially in
prostate carcinoma with metastases, Spm levels are
reduced. Hence, a dramatic decrease of the prostate
Spm content could indicate a conversion of prostate
tissue from a benign to a malignant phenotype. In vitro
studies [80, 81] demonstrated differential sensitivity
of prostate tumor cell lines to Spm. Exposure of cells
to Spm induced cell cycle arrest and apoptosis in the
weakly metastatic AT2.1 cell line but not in the highly
metastatic AT3.1 cell line. We also have established
that total PA content was higher in highly metastatic
rat prostate cancer cell lines (MATLylu) than AT2 cell
line, which is low metastatic one (unpublished data).
A possible explanation these facts may be in the dif
ferent induction of antizyme in Spmsensitive and
Spminsensitive cells. In the Spminsensitive cells,
ODC antizyme levels were not upregulated, thereby
failing to inhibit and degrade ODC [82].
As it is mentioned above, PAs are important for
prostate cell growth and function, for this reason
interference with PA homeostasis offer a promising
target for chemotherapy of prostate cancer. Inhibitors
of PA biosynthesis and PA analogues can affect PA
homeostasis. Different compounds are able to inhibit
the PA biosynthetic enzymes activities [52].
DFMO is the most widely studied ODC inhibitor
causing depletion of Put and Spd pools without signifi
cant effect on Spm levels [83–85]. DFMO treatment
has remarkable inhibitory effects on cell growth of
cultured prostate cancer cells, and this inhibition may
182 Experimental Oncology 28, 178–186, 2006 (September)
be reversed by the addition of PAs or their acetylated
derivatives in PC3, PC82 and androgenstimulated
LNCaP cells [85]. However, DFMO was ineffective
in vivo, perhaps due to the compensatory uptake of
PAs from extracellular sources [76, 86]. Another ODC
inhibitor, methylacetylenic putrescine (MAP) inhibited
the growth of PC3 and some other cell lines, and slow
ly growing cells were more sensitive to its action [87].
Also, in vitro inhibitory effect on ODC activity of the
naturally occurring garlic derivatives [88] and green
tea polyphenols were demonstrated [89].
Experimental studies showed that PA analogues
have significant antitumor activity in solid tumors.
(Table). The prostate tissue preferentially takes up Put
and this uptake can be enhanced by DFMO. Put ana
logues have chemotherapeutic potential, especially
in combination with DFMO. Monoaziridinylputrescine
(AZP) inhibited growth of PC3 human prostate cells,
while cotreatment with DFMO increased the growth
inhibitory effect [94].
Symmetrically substituted bis(ethyl) analogues
of Spm and Spd are highly effective in cell growth
inhibition [53]. Some of these analogues BE333,
BENSpm or DENSpm are assessed in clinical tests
[90, 91, 93, 95, 96]. BE333 has different effects on
cell growth and PA homeostasis in different prostate
carcinoma cells: androgen independent cells were
the most sensitive, whereas androgendependent
cells were insensitive. Generally, degree of cell growth
inhibition correlated with SSAT stimulation. BE4444
was more effective compared to BE333 in inhibiting
the growth of DU145, TsuPr1 and DuPro1 cells [90].
In all tumors treated with the BE4444, the levels of
Spd and Spm were shown to decrease whereas Put
level was not affected. The reason of the lack of PA
depletion in vivo is probably uptake of PAs via food
consumption.
Recently, the effect of a Spm analogue BIS has
been studied on DU145 and PC3 cells [92]. BIS
showed dosedependent cytotoxic effect on prostate
cancer cells in vitro and this effect was realized via
apoptotic pathway. Besides, combination of treat
ment of BIS with irradiation strikingly increased the
number of apoptotic cells. Therefore, application of
BIS results in increased radiosensitivity of human
prostate cancer
The key enzymes involved in the cell cycle ma
chinery belong to the group of homologous serine/
threonine protein kinases known as cyclindependent
kinases (CDKs), which typically contain cyclin as a
regulatory subunit. Up to date, nine CDKs have been
identified in human and animals [97]. These enzymes
preferentially phosphorylate lamins, vimentin, caldes
mon, and histon H1, which play a key role in cell divi
sion during the G2/M phase of the cell cycle, as well
as proteins RBs, E2Fs, DP1, RNApolymerase II, EF2
implicated in activation of the Sphasespecific genes
involved in G1/S boundary [98].
It is well known that there both ODC and PA con
centrations during the cell cycle are changed [99].
There is an early peak in ODC content at G1phase,
followed by an increase in PA content, and the se
cond increase during G2phase and prior to mitosis
[100]. Thus, both PAs and cyclin/CDKs show phased
changes throughout the cell cycle, but the interac
tion between these two sets of regulatory molecules
remains to be defined. One suggestion is that PAs
regulate cyclin degradation [101]. Intracellular PA
concentrations have been reported to determine both
up and downregulation of important cellular check
points within the cell cycle, and this may in part, explain
why their concentrations are controlled throughout the
cycle [102, 103].
The enzymatic activity of CDKs in normal somatic
cells is precisely regulated by several mechanisms.
The natural CDK inhibitors (CDKIs) play an important
role in this process [104]. Recently, natural peptide
CDK inhibitors have been shown to play an important
regulatory role in cell differentiation, proliferation,
senescence, and programmed cell death [105]. It
has also been demonstrated that the effects of these
endogenous inhibitors may be partly mimicked by
several different types of synthetic inhibitors including
butyrolactone I, flavopiridol, 2,6,9trisubstituted pu
rines such as olomoucine (OC), roscovitine, and pur
valanol, paullones, indirubins, and others [106–108].
These proteins bind to the cyclinCDK complex and
inhibit its activity. Consequently, the entry of the cell
into the cell cycle is blocked. Due to the fact that the
families of natural CDKIs or genes that control CDKIs
transcription (e. g., p53) belong to the most frequently
mutated proteins in cancer cells, the molecules that
could mimic their biological activities are attractive
candidates for anticancer treatment [109, 110].
Upon the study of plant hormones, cytokinins,
specific inhibitors of the CDKs were identified, in
particular 6benzylamino2(2hydroxyethylamino)
9methylpurine (OC). At micromolar concentrations
OC selectively blocks CDK1, CDK2 and CDK5 ki
nases [111]. OC does not exert an inhibitory effect
on the major cellular kinases such as cAMP and
cGMPdependent kinases, protein kinase C and Src
kinases, however, it is able to block cells at the G1/S
and G2/M boundaries [111]. OC has low cytotoxicity
in vitro [111]. Another purine derivative, roscovitine,
induces apoptosis under normal growth conditions.
Roscovitine is a novel substance with potent inhibitory
activity towards CDK1, high selectivity and antimitotic
activity [112]. It was revealed that OC and roscovitine
act as competitive inhibitors of in ATPbinding sites of
kinases. The study of specificity of these inhibitors has
shown that only the cell cycle regulating cdc2/cyclin B,
CDK2/cyclin A and CDK2/cyclin E kinases, the brain
CDK5/p25 kinase and ERK1 are inhibited by OC and
roscovitine. Structureactivity studies and analysis
of OC/CDK2 and roscovitine/CDK2 cocrystal struc
tures confirmed that OC and roscovitine bind in the
ATPbinding pocket of CDK2, but showed that the
purine rings of OC/roscovitine and ATP are located in
a totally different orientation. The antimitotic effects of
Experimental Oncology 28, 178–186, 2006 (September) 183
OC and roscovitine were investigated in a large variety
of cellular models. The compounds inhibit both G1/S
and G2/M transitions [113, 114].
Recently new groups of CDKIs with high specifici
ty and efficacy have been synthesized [115]. They
are strongly cytotoxic toward tumor cell lines in vitro.
One of them, bohemine (BOH) and OC II were found
to be effective in vivo [116]. On the other hand, OC II
is the most active CDK1 inhibitor in vitro against tumor
cells [117].
During the experimental studies, Mad’arova et al.
[118] discovered that both BOH and OC were potent
inhibitors of cell growth and viability, especially for
androgen responsive cells; BOH was 2–3 times more
effective than OC toward human prostate cancer cell
lines. In our research, we estimated that treatment
with BOH or OC II inhibited in vitro cell growth of highly
metastatic (MATLylu) and low metastatic (AT2) rat
prostate cancer cell lines and caused drastic reduction
of Put, Spd and Spm levels (unpublished data).
In conclusion, PAs are promising biomarkers for
prostate cancer, and the compounds targeting their
metabolism should be studied for possible chemo
therapeutical application.

полиамины и рак предстательной железы
Во многих развитых странах рак предстательной железы занимает первое место как причина смертности вследствие
онкологических заболеваний. Ткань предстательной железы характеризуется наиболее высоким уровнем содержания
полиаминов в сравнении с другими органами человека, причем в ткани карциномы простаты их содержание еще выше. Эти
биомолекулы синтезируются эпителиальными клетками предстательной железы и принимают участие во многих биохимических
процессах, включая пролиферацию клеток, регуляцию клеточного цикла и синтез белков. В обзоре обсуждаются функции
полиаминов в клетке, их участие в процессах апоптоза и потенциальная роль в качестве биомаркеров при раке предстательной
железы. Кроме того, приведены новые данные о разработке препаратов, в частности ингибитора циклинзависимой киназы,
предназначенных для лечения рака предстательной железы.
Ключевые слова: рак предстательной железы, полиамины, ингибитор CDK, оломуцин, богемин, росковитин.
