Comparative molecular genetic profiles of anaplastic astrocytomas/glioblastomas multiforme and their subsequent recurrences. (1/1100)

Malignant glial tumors (anaplastic astrocytomas and glioblastomas multiforme) arise mostly either from the progression of low grade precursor lesions or rapidly in a de novo fashion and contain distinct genetic alterations. There is, however, a third subset of malignant gliomas in which genetic lesions remain to be identified. Following surgical resection, all gliomas appear to have an inherent tendency to recur. Comparative molecular analysis of ten primary malignant gliomas (three anaplastic astrocytomas and seven glioblastomas multiforme) with their recurrences identified two distinct subgroups of recurrent tumors. In one group, primary tumors harbored genetic aberrations frequently associated with linear progression or de novo formation pathways of glial tumorigenesis and maintained their genetic profiles upon recurrence. In the other subset with no detectable known genetic mutations at first presentation, the recurrent tumors sustained specific abnormalities associated with pathways of linear progression or de novo formation. These included loss of genes on chromosomes 17 and 10, mutations in the p53 gene, homozygous deletion of the DMBTA1 and p16 and/ or p15 genes and amplification and/or overexpression of CDK4 and alpha form of the PDGF receptor. Recurrent tumors from both groups also displayed an abnormal expression profile of the metalloproteinase, gel A, and its inhibitor, TIMP-2, consistent with their highly invasive behavior. Delineation of the molecular differences between malignant glioblastomas and their subsequent recurrences may have important implications for the development of rational clinical approaches for this neoplasm that remains refractory to existing therapeutic modalities.  (+info)

Coupling of the cell cycle and myogenesis through the cyclin D1-dependent interaction of MyoD with cdk4. (2/1100)

Proliferating myoblasts express the muscle determination factor, MyoD, throughout the cell cycle in the absence of differentiation. Here we show that a mitogen-sensitive mechanism, involving the direct interaction between MyoD and cdk4, restricts myoblast differentiation to cells that have entered into the G0 phase of the cell cycle under mitogen withdrawal. Interaction between MyoD and cdk4 disrupts MyoD DNA-binding, muscle-specific gene activation and myogenic conversion of 10T1/2 cells independently of cyclin D1 and the CAK activation of cdk4. Forced induction of cyclin D1 in myotubes results in the cytoplasmic to nuclear translocation of cdk4. The specific MyoD-cdk4 interaction in dividing myoblasts, coupled with the cyclin D1-dependent nuclear targeting of cdk4, suggests a mitogen-sensitive mechanism whereby cyclin D1 can regulate MyoD function and the onset of myogenesis by controlling the cellular location of cdk4 rather than the phosphorylation status of MyoD.  (+info)

Cyclin D-CDK subunit arrangement is dependent on the availability of competing INK4 and p21 class inhibitors. (3/1100)

The D-type cyclins and their major kinase partners CDK4 and CDK6 regulate G0-G1-S progression by contributing to the phosphorylation and inactivation of the retinoblastoma gene product, pRB. Assembly of active cyclin D-CDK complexes in response to mitogenic signals is negatively regulated by INK4 family members. Here we show that although all four INK4 proteins associate with CDK4 and CDK6 in vitro, only p16(INK4a) can form stable, binary complexes with both CDK4 and CDK6 in proliferating cells. The other INK4 family members form stable complexes with CDK6 but associate only transiently with CDK4. Conversely, CDK4 stably associates with both p21(CIP1) and p27(KIP1) in cyclin-containing complexes, suggesting that CDK4 is in equilibrium between INK4 and p21(CIP1)- or p27(KIP1)-bound states. In agreement with this hypothesis, overexpression of p21(CIP1) in 293 cells, where CDK4 is bound to p16(INK4a), stimulates the formation of ternary cyclin D-CDK4-p21(CIP1) complexes. These data suggest that members of the p21 family of proteins promote the association of D-type cyclins with CDKs by counteracting the effects of INK4 molecules.  (+info)

Induced expression of p16(INK4a) inhibits both CDK4- and CDK2-associated kinase activity by reassortment of cyclin-CDK-inhibitor complexes. (4/1100)

To investigate the mode of action of the p16(INK4a) tumor suppressor protein, we have established U2-OS cells in which the expression of p16(INK4a) can be regulated by addition or removal of isopropyl-beta-D-thiogalactopyranoside. As expected, induction of p16(INK4a) results in a G1 cell cycle arrest by inhibiting phosphorylation of the retinoblastoma protein (pRb) by the cyclin-dependent kinases CDK4 and CDK6. However, induction of p16(INK4a) also causes marked inhibition of CDK2 activity. In the case of cyclin E-CDK2, this is brought about by reassortment of cyclin, CDK, and CDK-inhibitor complexes, particularly those involving p27(KIP1). Size fractionation of the cellular lysates reveals that a substantial proportion of CDK4 participates in active kinase complexes of around 200 kDa. Upon induction of p16(INK4a), this complex is partly dissociated, and the majority of CDK4 is found in lower-molecular-weight fractions consistent with the formation of a binary complex with p16(INK4a). Sequestration of CDK4 by p16(INK4a) allows cyclin D1 to associate increasingly with CDK2, without affecting its interactions with the CIP/KIP inhibitors. Thus, upon the induction of p16(INK4a), p27(KIP1) appears to switch its allegiance from CDK4 to CDK2, and the accompanying reassortment of components leads to the inhibition of cyclin E-CDK2 by p27(KIP1) and p21(CIP1). Significantly, p16(INK4a) itself does not appear to form higher-order complexes, and the overwhelming majority remains either free or forms binary associations with CDK4 and CDK6.  (+info)

Differential roles for cyclin-dependent kinase inhibitors p21 and p16 in the mechanisms of senescence and differentiation in human fibroblasts. (5/1100)

The irreversible G1 arrest in senescent human diploid fibroblasts is probably caused by inactivation of the G1 cyclin-cyclin-dependent kinase (Cdk) complexes responsible for phosphorylation of the retinoblastoma protein (pRb). We show that the Cdk inhibitor p21(Sdi1,Cip1,Waf1), which accumulates progressively in aging cells, binds to and inactivates all cyclin E-Cdk2 complexes in senescent cells, whereas in young cells only p21-free Cdk2 complexes are active. Furthermore, the senescent-cell-cycle arrest occurs prior to the accumulation of the Cdk4-Cdk6 inhibitor p16(Ink4a), suggesting that p21 may be sufficient for this event. Accordingly, cyclin D1-associated phosphorylation of pRb at Ser-780 is lacking even in newly senescent fibroblasts that have a low amount of p16. Instead, the cyclin D1-Cdk4 and cyclin D1-Cdk6 complexes in these cells are associated with an increased amount of p21, suggesting that p21 may be responsible for inactivation of both cyclin E- and cyclin D1-associated kinase activity at the early stage of senescence. Moreover, even in the late stage of senescence when p16 is high, cyclin D1-Cdk4 complexes are persistent, albeit reduced by +info)

Progesterone inhibits estrogen-induced cyclin D1 and cdk4 nuclear translocation, cyclin E- and cyclin A-cdk2 kinase activation, and cell proliferation in uterine epithelial cells in mice. (6/1100)

The response of the uterine epithelium to female sex steroid hormones provides an excellent model to study cell proliferation in vivo since both stimulation and inhibition of cell proliferation can be studied. Thus, when administered to ovariectomized adult mice 17beta-estradiol (E2) stimulates a synchronized wave of DNA synthesis and cell division in the epithelial cells, while pretreatment with progesterone (P4) completely inhibits this E2-induced cell proliferation. Using a simple method to isolate the uterine epithelium with high purity, we have shown that E2 treatment induces a relocalization of cyclin D1 and, to a lesser extent, cdk4 from the cytoplasm into the nucleus and results in the orderly activation of cyclin E- and cyclin A-cdk2 kinases and hyperphosphorylation of pRb and p107. P4 pretreatment did not alter overall levels of cyclin D1, cdk4, or cdk6 nor their associated kinase activities but instead inhibited the E2-induced nuclear localization of cyclin D1 to below the control level and, to a lesser extent, nuclear cdk4 levels, with a consequent inhibition of pRb and p107 phosphorylation. In addition, it abrogated E2-induced cyclin E-cdk2 activation by dephosphorylation of cdk2, followed by inhibition of cyclin A expression and consequently of cyclin A-cdk2 kinase activity and further inhibition of phosphorylation of pRb and p107. P4 is used therapeutically to oppose the effect of E2 during hormone replacement therapy and in the treatment of uterine adenocarcinoma. This study showing a novel mechanism of cell cycle inhibition by P4 may provide the basis for the development of new antiestrogens.  (+info)

Re-expression of endogenous p16ink4a in oral squamous cell carcinoma lines by 5-aza-2'-deoxycytidine treatment induces a senescence-like state. (7/1100)

We have previously reported that a set of oral squamous cell carcinoma lines express specifically elevated cdk6 activity. One of the cell lines, SCC4, contains a cdk6 amplification and expresses functional p16ink4a, the other cell lines express undetectable levels of p16ink4a, despite a lack of coding-region mutations. Two of the cell lines, SCC15 and SCC40 have a hypermethylated p16ink4A promoter and a third cell line, SCC9, has a mutation in the p16ink4a promoter. Using the demethylation agent 5-aza-2'-deoxycytidine, we showed that the p16ink4a protein was re-expressed after a 5-day treatment with this chemical. One cell line, SCC15 expressed high levels of p16ink4a. In this line, cdk6 activity was decreased after 5-aza-2'deoxycytidine treatment, and the hypophosphorylated, growth suppressive form of the retinoblastoma tumor suppressor protein pRB was detected. Expression of p16ink4a persisted, even after the drug was removed and the cells expressed senescence-associated beta-galactosidase activity. Ectopic expression of p16ink4a with a recombinant retrovirus in this cell line also induced a similar senescence-like phenotype. Hence, it was possible to restore a functional pRB pathway in an oral squamous cell carcinoma line by inducing re-expression of endogenous p16ink4a in response to treatment with a demethylating agent.  (+info)

Defining the substrate specificity of cdk4 kinase-cyclin D1 complex. (8/1100)

cdk4 kinase-cyclin D1 complex (cdk4/D1) does not phosphorylate all of the sites within retinoblastoma protein (Rb) equally. Comparison of five phosphorylation sites within the 15 kDa C domain of Rb indicates that Ser795 is the preferred site of phosphorylation by cdk4/D1. A series of experiments has been performed to determine the properties of this site that direct preferential phosphorylation. For cdk4/D1, the preferred amino acid at the third position C-terminal to the phosphorylated serine/threonine is arginine. Substitution of other amino acids, including a conservative change to lysine, has dramatic effects on the rates of phosphorylation. This information has been used to mutate less favorable sites in Rb, converting them to sites that are now preferentially phosphorylated by cdk4/D1. A conserved site at Ser842 in the related pocket protein p107 is also preferentially phosphorylated by cdk4/D1. Although Rb and p107 differ significantly in sequence, the Rb Ser795 site can replace the p107 Ser842 site without affecting the rate of phosphorylation. These results suggest that although a determinant of specificity resides in the sequences surrounding the phosphorylated site, the structural context of the site is also a critical parameter of specificity.  (+info)

Excessive proliferation and migration of vascular smooth muscle cells (VSMCs) and adventitial fibroblasts play an important role in the pathobiology of vascular occlusive disease (eg, atherosclerosis, in-stent restenosis, transplant vasculopathy, and vessel bypass graft failure).1,2 Thus, understanding the molecular mechanisms that control hyperplastic growth and the locomotion of vascular cells should aid in the development of novel therapeutic strategies to reduce neointimal thickening.. Cell cycle progression is controlled by several cyclin-dependent kinases (CDKs) that associate with regulatory cyclins.3 Mitogenic stimuli activate CDK/cyclin holoenzymes, thus causing hyperphosphorylation of the retinoblastoma protein (pRb) and related pocket proteins from mid G1 to mitosis. CDK-dependent pRb hyperphosphorylation releases E2F transcription factors, thus contributing to the expression of several growth and cell cycle-regulatory genes with functional E2F-binding sites in their ...
The cyclin-dependent kinase (CDK) inhibitor p27Kip1 has been shown to regulate cellular proliferation via inhibition of CDK activities. routine and g27Kip1 (hereafter g27) can regulate CDK actions.1-3 The p27 protein was originally known as an inhibitor of CDK activities for things containing CDK2 and shown to inhibit cyclin E and cyclin A activities which regulate G1 and S phase traverse.4-6 In addition to CDK inhibition, g27 provides other multifarious connections with cyclin N/cdk4 processes putatively.7 Since cellular amounts of g27 are elevated in response to high cell thickness, serum deprival, and TGF, it was hypothesized g27 brought cells into quiescence and held them in G0 through the inhibition of CDK actions.8 Numerous reviews have got characterized the control of p27 including the control of its transcription,9,10 translation,11,12 post-translational adjustments.7,13,14 cellular localization15-19 and balance.20-23 The regulations of its stability has a main role in adjusting mobile ...

CDKs (Cyclin-dependent kinases) are serine-threonine kinases first discovered for their role in regulating the cell cycle. They are also involved in regulating transcription, mRNA processing, and the differentiation of nerve cells. CDKs are relatively small proteins, with molecular weights ranging from 34 to 40 kDa, and contain little more than the kinase domain. In fact, yeast cells can proliferate normally when their CDK gene has been replaced with the homologous human gene. By definition, a CDK binds a regulatory protein called a cyclin. Without cyclin, CDK has little kinase activity; only the cyclin-CDK complex is an active kinase.. There are around 20 Cyclin-dependent kinases (CDK1-20) known till date. CDK1, 4 and 5 are involved in cell cycle, and CDK 7, 8, 9 and 11 are associated with transcription.. CDK levels remain relatively constant throughout the cell cycle and most regulation is post-translational. Most knowledge of CDK structure and function is based on CDKs of S. pombe (Cdc2), S. ...

The randomised controlled trial (RCT) is the gold standard for evaluating the effects of health care interventions.1 Therefore, South African health policy and clinical guidelines should be based on well-conducted RCTs that ideally are conducted within the country to ensure local applicability. Conducting RCTs in South Africa faces numerous obstacles. Specialist training in the universities traditionally focuses on clinical experience and skills accrual, and lacks a research focus. Downscaled tertiary service units struggle to remain academically active,2 reducing the opportunities for local clinicians to acquire the epidemiological and statistical skills for conducting RCTs. Health professionals interested in clinical research may have to migrate to develop these skills. Opportunities to then practise those skills may only exist overseas, contributing to the professional brain drain.3 When research funding is not available from local sources, researchers become dependent on funds from donor ...
Progress through the G1phase of the mammalian cell cycle is regulated by the ordered synthesis, assembly, and activation of distinct cyclin-CDK holoenzymes (45, 46). Cyclins D1, D2, and D3 are up-regulated as cells exit from quiescence and associate with their major kinase partners CDK4 and CDK6 (3, 29, 32, 53). These two kinase molecules are highly homologous and associate exclusively with the D-type cyclins (3). Numerous studies have implicated cyclin D-CDK4-CDK6 complexes as key regulators of the cell cycle up to a hypothetical point during late G1 (24, 25), the restriction point, when hyperphosphorylation and inactivation of the retinoblastoma tumor suppressor gene product, pRB, occur (37, 44).. In contrast to mitotic cyclin-CDK complexes, the D-type cyclins do not automatically assemble into complexes with either CDK4 or CDK6. For example, when overexpressed in NIH 3T3 cells in the absence of serum, D-type cyclins and CDK4 do not interact efficiently (30). Hence, assembly of D-type cyclins ...

TY - JOUR. T1 - SU9516, a cyclin-dependent kinase 2 inhibitor, promotes accumulation of high molecular weight E2F complexes in human colon carcinoma cells. AU - Yu, Bo. AU - Lane, Maureen E.. AU - Wadler, Scott. PY - 2002/10/1. Y1 - 2002/10/1. N2 - The E2F family plays a critical role in the expression of genes required for entry into and progression through S phase. E2F-mediated transcription is repressed by the tumor suppressor retinoblastoma protein (pRb), which results in sequestration of E2F in a multiprotein complex that includes pRb. Derepression of E2F results from a series of complex phosphorylation events mediated by cyclin D/cdk4 and cyclin E/cdk2. We have employed a novel 3-substituted indolinone compound, 3-[1-(3H-imidazol-4-yl)-meth-(Z)-ylidene]-5-methoxy-1,3-dihydro-indol-2-one (SU9516), which selectively inhibits cdk2 activity (Lane et al., Cancer Res 2001;61:6170-7) to investigate these events. Electrophoretic mobility gel shift assays were performed on SU9516-treated and ...

If you have a question about this talk, please contact Caroline Newnham.. Host: Viji Draviam. Tissue homeostasis in metazoans is regulated by transitions of cells between quiescence and proliferation. The hallmark of proliferating populations is progression through the cell cycle, which is driven by Cyclin-dependent kinase (CDK) activity. I will discuss our recent development of a live-cell sensor for CDK2 activity and the finding that proliferating cells bifurcate into two populations as they exit mitosis. Some cells immediately commit to the next cell cycle by building up CDK2 activity from an intermediate level, while other cells lack CDK2 activity and enter a transient state of quiescence. This bifurcation is directly controlled by the CDK inhibitor p21 and is regulated by mitogens during a restriction window at the end of the previous cell cycle. We are currently exploring the role of cell stress in controlling this bifurcation in an attempt to uncover the root cause of this striking ...
Abstract. Dysregulation of cyclin-dependent kinase (CDK)4 or CDK6 activity by gain of function or loss of inhibition is one of the most frequent aberrations in
Cyclin-dependent kinases (CDKs) are core components of the cell cycle machinery that govern the transition between phases during cell cycle progression. Genes involved in cell cycle are frequently mutated in human cancer and deregulated CDK activity repr
The researchers examined a protein called cyclin-dependent kinase 2 (CDK2), which works as a quality control inspector. As normal cells divide, they pause in the replication process when they find inaccurate genetic code embedded in their DNA. The health and well-being of offspring cells depends on accurate genetic code transfer from one generation of cells to the next. The Mayo researchers showed that when errors in genes are irreparable, CDK2 modifies another cellular protein -- FOXO1 -- to send a signal that results in the death of the cell. This protein-to-protein relationship invites targeted drug intervention to control unregulated growth of cancer cells ...

Cyclin D-Cdk4 complexes have a demonstrated role in G1 phase, regulating the function of the retinoblastoma susceptibility gene product (Rb). Previously, we have shown that following treatment with low doses of UV radiation, cell lines that express wild-type p16 and Cdk4 responded with a G2 phase cell cycle delay. The UV-responsive lines contained elevated levels of p16 post-treatment, and the accumulation of p16 correlated with the G2 delay. Here we report that in UV-irradiated HeLa and A2058 cells, p16 bound Cdk4 and Cdk6 complexes with increased avidity and inhibited a cyclin D3-Cdk4 complex normally activated in late S/early G2 phase. Activation of this complex was correlated with the caffeine-induced release from the UV-induced G2 delay and a decrease in the level of p16 bound to Cdk4. Finally, overexpression of a dominant-negative mutant of Cdk4 blocked cells in G2 phase. These data indicate that the cyclin D3-Cdk4 activity is necessary for cell cycle progression through G2 phase into mitosis and

Substituted guanines and pyrimidines were tested as inhibitors of cyclin B1/CDK1 and cyclin A3/CDK2 and soaked into crystals of monomeric CDK2. O6-Cyclohexylmethylguanine (NU2058) was a competitive inhibitor of CDK1 and CDK2 with respect to ATP (Ki values: CDK1, 5 +/- 1 microM; CDK2, 12 +/- 3 microM) and formed a triplet of hydrogen bonds (i.e., NH-9 to Glu 81, N-3 to Leu 83, and 2-NH2 to Leu 83). The triplet of hydrogen bonding and CDK inhibition was reproduced by 2,6-diamino-4-cyclohexylmethyloxy-5-nitrosopyrimidine (NU6027, Ki values: CDK1, 2.5 +/- 0.4 microM; CDK2, 1.3 +/- 0.2 microM). Against human tumor cells, NU2058 and NU6027 were growth inhibitory in vitro (mean GI50 values of 13 +/- 7 microM and 10 +/- 6 microM, respectively), with a pattern of sensitivity distinct from flavopiridol and olomoucine. These CDK inhibition and chemosensitivity data indicate that the distinct mode of binding of NU2058 and NU6027 has direct consequences for enzyme and cell growth inhibition.

Cyclin-dependent kinases (CDKs) contribute to the cancer hallmarks of uncontrolled proliferation and increased survival. As a result, over the last two decades substantial efforts have been directed towards identification and development of pharmaceutical CDK inhibitors. Insights into the biological consequences of CDK inhibition in specific tumor types have led to the successful development of CDK4/6 inhibitors as treatments for certain types of breast cancer. More recently, a new generation of pharmaceutical inhibitors of CDK enzymes that regulate the transcription of key oncogenic and pro-survival proteins, including CDK9, have entered clinical development. Here, we provide the first disclosure of the chemical structure of fadraciclib (CYC065), a CDK inhibitor and clinical candidate designed by further optimization from the aminopurine scaffold of seliciclib. We describe its synthesis and mechanistic characterization. Fadraciclib exhibits improved potency and selectivity for CDK2 and CDK9 ...

  • In mammalian cells, cell cycle is activated by CDK6 in the early G1 phase through interactions with cyclins D1, D2 and D3. (wikipedia.org)
  • However, in recent years, new evidence proved that the presence of CDK6 is not essential for proliferation in every cell type, the cell cycle has a complex circuitry of regulation and the role of CDK6 might be more important in certain cell types than in others, where CDK4 or CDK2 can act as protein kinases compensating its role.

  • Antibodies against cAMP-dependent protein kinase (PKA) and cGMP-dependent protein kinase (PKG) were obtained from Calbiochem Corp. cdk2, cdk4, and cyclin E were purchased from Santa Cruz Biochemicals. (ahajournals.org)
  • Activation of the MEK1/ERK pathway neither triggered degradation of the CDK inhibitor kinase inhibitory protein-1 (p27 Kip1 ) nor led to activation of cyclin E- and A-dependent CDK2, and such cells did not enter the DNA synthetic (S) phase of the cell division cycle. (pnas.org)
  • The cyclin E-CDK2 holoenzyme contributes to RB phosphorylation ( 17 - 19 ), phosphorylates p27 Kip1 to trigger its ubiquitin-mediated degradation ( 20 - 22 ), and likely modifies components of preinitiation complexes to trigger DNA replication per se ( 23 , 24 ). (pnas.org)
