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 ...

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 ...

To identify additional functional activity of the CDK9 complex, we conducted immunoprecipitation (IP) enrichment-stable isotope labeling LC-MS/MS of the CDK9 ...

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 ...

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

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 ...
