Available in PDF, EPUB and Kindle. Book excerpt: Mitogen-activated protein kinase (MAPK) cascades convey signals in eukaryotic cells through the sequential phosphorylation and activation of three protein kinases. In yeast, mating and filamentous growth share multiple components of a single MAPK cascade. These kinases are the MAPKKK Ste 11, the MAPKK Ste7 and two MAPKs, Fus3 and Kss1. The transcription factor Ste 12 is the target of both developmental pathways. The first part of this thesis addressed the mechanisms that ensure signal fidelity between the two signal outputs. This work challenges the model that the MAPK Fus3 ensures specificity in the mating response by physically occluding the MAPK Kss1 from the active Ste5 complex. I demonstrated that deletion of either individual MAPK had little affect on the genome-wide transcriptional response to pheromone. Further, catalytically inactive versions of Fus3 largely failed to attenuate the transcriptional response to pheromone in fus3Delta cells, and the exposure to mating pheromone stimulated the kinase activity of both MAPKs. I thus propose that both Fus3 and Kss1 are bona fide components of the mating program. To define the role of distal MAPK components in invasive growth and the presence of an associated transcriptional program, I performed genome-wide transcriptional analysis on combinatorial deletion strains of FUS3, KSS1, RST1 and RST2. This analysis revealed that Rst1 and Fus3 are the dominant inhibitors of invasive growth. By comparing transcriptional profiles of invasive versus non-invasive strains, I demonstrated that there is no concrete transcriptional program associated with invasive growth. Thus, invasive growth can be viewed as a component of the pheromone response. The second part of this thesis focuses on the Mitotic Exit Network (MEN), a signaling cascade that is activated at the end of mitosis to shut down cyclin-dependent kinase (CDK) activity. To identify novel MEN regulators, I used a high-throughput genetic approach to identify synthetic lethal interactions with nine men mutants. In total, 84 genes were identified that I named MEN Interactors (MNIs). The confirmed genetic interactions have provided connections to pathways with previously uncharacterized roles in mitotic exit. Furthermore, this study reveals that the PKC/MAPK pathway may not function in a linear manner with respect to MEN.

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 DNA Replication written by Hisao Masai and published by Springer. This book was released on 2018-01-22 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the latest trends and future directions of DNA replication research. The contents reflect upon the principles that have been established through the genetic and enzymatic studies of bacterial, viral, and cellular replication during the past decades. The book begins with a historical overview of the studies on eukaryotic DNA replication by Professor Thomas Kelly, a pioneer of the field. The following chapters include genome-wide studies of replication origins and initiation factor binding, as well as the timing of DNA replications, mechanisms of initiation, DNA chain elongation and termination of DNA replication, the structural basis of functions of protein complexes responsible for execution of DNA replication, cell cycle-dependent regulation of DNA replication, the nature of replication stress and cells’ strategy to deal with the stress, and finally how all these phenomena are interconnected to genome instability and development of various diseases. By reviewing the existing concepts ranging from the old principles to the newest ideas, the book gives readers an opportunity to learn how the classical replication principles are now being modified and new concepts are being generated to explain how genome DNA replication is achieved with such high adaptability and plasticity. With the development of new methods including cryoelectron microscopy analyses of huge protein complexes, single molecular analyses of initiation and elongation of DNA replication, and total reconstitution of eukaryotic DNA replication with purified factors, the field is enjoying one of its most exciting moments, and this highly timely book conveys that excitement to all interested readers.
Download or read book Principles of Cell Proliferation written by J. R. Heath and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controlled expansion of cell populations is a fundamental feature of living organisms, being a finely-tuned balance between cell proliferation and cell death. This book aims to explain the molecular mechanisms that lie behind the multiplication and survival of eukaryotic cells. This encompasses both the normal regulation of cell populations in development or physiological adaptation and pathological mechanisms of cell cycle control in cancer. Principles of Cell Proliferation progressively introduces the function of growth factors, receptors, signal transduction pathways, gene expression and the conserved mechanisms of the cell cycle engine. This provides a context for understanding the mechanistic consequences of the genetic alterations in oncogenes and tumour suppresser genes which underlie tumour formation. The book should satisfy advanced level courses in Cell Proliferation, Cell Cycle Control and Cancer Biology for biologists, biochemists and medical students. The book comes at a time when the underlying molecular mechanisms of cancer are beginning to be unravelled. Ideal for advanced level courses in Cell Proliferation, Cell Cycle or Cancer Biology. An accessible account of a subject many students find complex.
