This book was released on 2010 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitogen-activated protein kinase (MAPK) cascades in eukaryotic cells act in multiple pathways that share signaling components. Saccharomyces cerevisiae, the budding yeast, is an ideal model to study MAPK signaling specificity because its mating and invasive growth pathways share an entire cascade yet maintain specificity. The cascade contains the MAPK kinase kinase Ste11, MAPK kinase Ste7 and the MAPK Kss1. In addition there is another MAPK Fus3 that acts in mating. It has been proposed that Ste5, the scaffold for MAPK cascade, and Ste7 docking sites for Fus3 and Kss1 may promote specificity. Here the role of Ste7 docking sites in combination with Ste5 scaffolding of Ste7 was analyzed to understand signal transduction in both pathways. Results indicate that the two previously identified docking sites on Ste7 function in signal transduction for both mating and invasive growth. Fus3 can be phosphorylated in the absence of docking sites but requires the sites for full activation. Kss1 is entirely dependent on docking sites for its activation. In contrast, Ste5 scaffolding of Ste7 is required for mating but not for invasive growth. In absence of scaffolding, phosphorylation of Fus3 is reduced dramatically and level of Kss1 activation is reduced moderately. Interestingly, this moderate Kss1 activation by mating pheromone leads to a low-level induction of invasive growth genes but not mating genes, indicating that mating genes have a higher threshold for activation by Kss1. The low-level induction suggests that amount of active Kss1 is important for invasive growth and further indicates that Fus3-mediated negative feedback that controls Kss1 activation is critical in promoting mating specificity. The conclusion from these results is that Ste5 contributes to mating and invasive growth but it is only crucial for mating. The docking sites on Ste7 are crucial for both mating and invasive growth.
Book Synopsis Protein-protein Interactions in the Assembly and Regulation of MAP Kinase Pathways by : Roby Paul Bhattacharyya
Download or read book Protein-protein Interactions in the Assembly and Regulation of MAP Kinase Pathways written by Roby Paul Bhattacharyya and published by . This book was released on 2005 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: One key source of specificity is the assembly of appropriate catalytic signaling elements into pathway-dedicated signaling complexes, often in response to a specific stimulus. Such complexes ensure that, once activated, each signaling component is most likely to encounter, and therefore signal to, its appropriate downstream partner. In this manner, the problem of specific information transfer is reduced to the biochemically simpler problem of specific protein recognition required to assemble these signaling complexes.

Book Synopsis Intracellular Signaling Mediators in the Circulatory and Ventilatory Systems by : Marc Thiriet
Download or read book Intracellular Signaling Mediators in the Circulatory and Ventilatory Systems written by Marc Thiriet and published by Springer Science & Business Media. This book was released on 2012-09-26 with total page 1073 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volumes in this authoritative series present a multidisciplinary approach to modeling and simulation of flows in the cardiovascular and ventilatory systems, especially multiscale modeling and coupled simulations. The cardiovascular and respiratory systems are tightly coupled, as their primary function is to supply oxygen to and remove carbon dioxide from the body's cells. Because physiological conduits have deformable and reactive walls, macroscopic flow behavior and prediction must be coupled to phenomenological models of nano- and microscopic events in a corrector scheme of regulated mechanisms when the vessel lumen caliber varies markedly. Therefore, investigation of flows of blood and air in physiological conduits requires an understanding of the biology, chemistry, and physics of these systems together with the mathematical tools to describe their functioning. Volume 4 is devoted to major sets of intracellular mediators that transmit signals upon stimulation of cell-surface receptors. Activation of signaling effectors triggers the release of substances stored in cellular organelles and/or gene transcription and protein synthesis. Complex stages of cell signaling can be studied using proper mathematical models, once the role of each component is carefully handled. Volume 4 also reviews various categories of cytosolic and/or nuclear mediators and illustrates some major signal transduction pathways, such as NFkappaB axis, oxygen sensing, and mechanotransduction.
Book Synopsis Signaling by Receptor Tyrosine Kinases by : Joseph Schlessinger
Download or read book Signaling by Receptor Tyrosine Kinases written by Joseph Schlessinger and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Receptor tyrosine kinases are cell-surface receptors that respond to numerous hormones and growth factors, including insulin, insulin-like growth factors, epidermal growth factor, and nerve growth factor. They activate highly conserved intracellular signaling pathways that regulate cell proliferation, differentiation, and metabolism, playing essential roles in developing and adult animals. This book examines the nature of these receptors and their ligands, the molecular mechanisms that they regulate within cells, and the roles of the receptors in normal physiology and control of embryogenesis. It also discusses how dysfunction of these mechanisms can contribute to cancer and other diseases.
Book Synopsis The Fungal Cell Wall by : Jean-Paul Latgé
Download or read book The Fungal Cell Wall written by Jean-Paul Latgé and published by Springer Nature. This book was released on 2020-08-12 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates, that the fungal cell wall is critical for the biology and ecology of all fungi and especially for human fungal pathogens. Readers will learn, that the composition of the fungal cell wall is a unique structure, which cannot be found in the human host. Consequently, the chapters outline, how the immune systems of both animals and humans have evolved to recognize conserved and unique elements of the fungal cell wall. As an application example, the authors also show, that the three-dimensional structures of the cell wall are excellent targets for the development of antifungal agents and chemotherapeutic strategies. With the combination of biological findings and medical outlooks, this volume is a fascinating read for scientists, clinicians and biomedical students.

Download or read book Autophagy and Cancer written by Hong-Gang Wang and published by Springer Science & Business Media. This book was released on 2013-03-30 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the explosion of information on autophagy in cancer, this is an opportune time to speed the efforts to translate our current knowledge about autophagy regulation into better understanding of its role in cancer. This book will cover the latest advances in this area from the basics, such as the molecular machinery for autophagy induction and regulation, up to the current areas of interest such as modulation of autophagy and drug discovery for cancer prevention and treatment. The text will include an explanation on how autophagy can function in both oncogenesis and tumor suppression and a description of its function in tumor development and tumor suppression through its roles in cell survival, cell death, cell growth as well as its influences on inflammation, immunity, DNA damage, oxidative stress, tumor microenvironment, etc. The remaining chapters will cover topics on autophagy and cancer therapy. These pages will serve as a description on how the pro-survival function of autophagy may help cancer cells resist chemotherapy and radiation treatment as well as how the pro-death functions of autophagy may enhance cell death in response to cancer therapy, and how to target autophagy for cancer prevention and therapy − what to target and how to target it.
