Download or read book Regulation of G1 Phase Progression written by Johannes Boonstra and published by Springer Science & Business Media. This book was released on 2003-09-30 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this contribution, several specialists describe the current knowledge on the molecular networks that regulate cell cycle progression, with an emphasis on the G1 phase of the cell cycle. The first part of Regulation of G1 Phase Progression is concerned with the individual molecules that form the network, including cyclins, cyclin-dependent kinases, inhibitors of these kinases and retinoblastoma and p53. The second section describes the signaling cascades by which external factors influence the cell cycle network, including mitogens, the extracellular matrix, nutrients and oxygen radicals. The last section describes the effects of specific external conditions on cell cycle progression and are presented such as serum starvation and subsequent re-addition and stress conditions (heat, osmolarity). The final two chapters describe the relation between cell cycle progression with cell differentiation and with apoptosis.

Download or read book The Story of the Promiscuous Substrate an Investigation of the Role of the Pi3k Pathway in P27kip1 Regulation written by Michelle Davila Larrea and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Deregulated cell proliferation, resulting from disruption of cell cycle control, is characteristic of many cancers. In normal cells, cell cycle progression is mediated by a family of cyclin dependent kinases (Cdks) that are positively regulated by associated cyclins. The activities of these cyclin-Cdk complexes are regulated by two protein families: the inhibitors of Cdk4 (INK4) and the kinase inhibitor proteins (KIP). p27 is a KIP family member that can inhibit cyclin E-Cdk2 activity. It also plays a role in the assembly and nuclear import of cyclin D-Cdk4 in early G1. p27 has been shown to be deregulated in human cancers by accelerated proteolysis, sequestration in cyclin D-Cdk complexes, and mislocalization to the cytoplasm. The causes of these alterations are not fully understood, but result, at least in part, from changes in signal transduction pathways that alter p27 phosphorylation and function. Activation of both the Ras/Raf/ mitogen activated protein kinase (MAPK) and the phospho-inositol 32 kinase (PI3K) pathways have been shown to alter p27 function and to activate p27 degradation in different cell types. In this thesis, I have investigated the roles played by two kinases downstream of PI3K, protein kinase B (PKB) and p90 ribosomal S6 kinase (RSK1), in regulation of p27 function. I observed that PKB-mediated phosphorylation of p27 promotes p27-cyclin D1-Cdk4 assembly. p27 phosphorylation by RSK1 alters the interaction of p27 with cytoskeleton proteins to promote cell motility. I observed that PKB activation and the appearance of p27pT157 and p27pT198 in early G1 precede p27-cyclin D1-Cdk4 assembly. PI3K/PKB inhibition dissociates cellular p27-cyclin D1-Cdk4 and p27T157A, p27T198A and p27T157A/T198A bind cellular cyclin D1 and Cdk4 poorly. Cellular p27pT157 and p27pT198 co-precipitate with Cdk4 but not Cdk2. p27 phosphorylation by PKB increases the ability of p27 to assemble cyclin D1-Cdk4 in vitro, but yields inactive Cdk4. While Src does not affect p272s ability to assemble cyclin D1-Cdk4, Src treatment yields catalytically active p27-cyclin D1-Cdk4. Thus, while PKB dependent p27 phosphorylation promotes p27-cyclin D1-Cdk4 assembly, tyrosine phosphorylation of p27 is required for activation of p27-cyclin D1-Cdk4 complexes. Constitutive activation of PKB and Abl or Src family kinases in cancers would drive p27 phosphorylation, increase cyclin D1-Cdk4 assembly and activation, and reduce the cyclin E-Cdk2 inhibitory function of p27. Combined therapy with both Src and PI3K/PKB inhibitors may reverse this process. While RSK1 has been shown to phosphorylate p27, the key phosphorylation sites and the consequence of this phosphorylation event were not fully elucidated. I have shown that RSK1 activation in early G1 precedes p27 phosphorylation at T157 and T198 in synchronized cell populations. Overexpression of RSK1 causes resistance to G1 arrest by TGF-.́ Moreover, cells overexpressing RSK1 show an increase in p27 phosphorylation at T198, increased p27 stability, and an increase in p27 binding to Cdk4. In addition, RSK1-transfectants have increased cytoplasmic p27, associated with increased cell motility and inhibition of RhoA. p27 phosphorylation by recombinant RSK1 increases p27 binding to RhoA, while p27T157A/T198A shows reduced association with RhoA in cells. Thus, phosphorylation of p27 at T198 by RSK1 promotes its binding to RhoA and loss of actin stress fiber stability. Oncogenic RSK1 activation may promote increased cancer cell migration and cancer metastasis. Taken together our results indicate that oncogenic activation of the PI3K pathway can contribute to loss of cyclin E-Cdk2 inhibitory action of p27 by at least two mechanisms. Activation of PKB and RSK1 signaling would promote cytoplasmic mislocalization of p27, p27-RhoA binding and inhibition of the RhoA pathway to augment cell motility. In addition, these phosphorylation events on p27 would increase the assembly of p27-cyclin D1-Cdk4 as a first step in a chain of events that would promote that nuclear import and activation of D-type cyclin Cdk complexes, shifting the equilibrium away from the Cdk2 inhibitory action of p27.

Download or read book Regulation of S6KL During Cell Cycle Progression written by Alton J. Joseph and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: mTOR (Mammalian Target ofRapamycin), PI3K (Phosphatidylinositol3-kinase) and MEK (Mitogen-activated protein kinase/ERK kinase) have been shown to be potent regulators of S6Kl at G1 phase of the cell cycle. Research has been concentrated at the G1 phase to elucidate mTOR's role in cell growth and proliferation. Limited information is available on the activity of mTOR, PI3K and ERKl/2 in cell cycle phases other than G1. Since we have observed that S6Kl is active in phases other than G1 our goal was to ascertain if mTOR, PI3K or ERKl/2 have a role in regulating S6Kl during these cell cycle phases. Using cell cycle analysis and immunoblot analysis we have determined here that mTOR and PI3K could play a role in regulating S6Kl at the G1/S transition in the cell cycle but there is also indications that mTOR and PI3K are potentially involved in regulating S6Kl in the phases post-G1/S of the cell cycle, indicating a complex interaction between the kinases used to regulate S6Kl during the cell cycle. ERKl/2 is demonstrated to have limited involvement in the regulation of S6Kl during the cell cycle.

This volume summarizes the current research on the role that signal transduction pathways play in the pathogenesis of cancer and how this knowledge may be used to develop the next generation of more effective and less toxic anticancer agents. Series Editor comments: "The biologic behavior of both normal and cancer cells is determined by critical signal transduction pathways. This text provides a comprehensive review of the field. Leading investigators discuss key molecules that may prove to be important diagnostic and/or therapeutic targets."
Download or read book PARP14 Regulates Cyclin D1 Expression to Promote Cell Cycle Progression written by Michael O'Connor and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT Cyclin D1 is an essential regulator of the G1-S cell cycle transition and is overexpressed in many cancers. Expression of Cyclin D1 is under tight cellular regulation controlled by many signaling pathways. Here I report that PARP14, a member of the poly (ADP-ribose) polymerase (PARP) family, is a regulator of cyclin D1 expression. Depletion of PARP14 leads to decreased cyclin D1 protein levels. In cells with a functional retinoblastoma (RB) protein pathway, this results in G1 cell cycle arrest and reduced proliferation. Mechanistically, I demonstrate that PARP14 controls cyclin D1 mRNA levels. Luciferase assays indicate that PARP14 specifically regulates cyclin D1 3'UTR mRNA stability. G1 arrest in PARP14-depleted cells is also dependent on an intact p53 pathway, specifically through the function of p21. My work uncovers a new role for PARP14 in promoting cell cycle progression through both cyclin D1 and the p53 pathway.
