Download or read book Beta Catenin and Ha ras Master Regulators of Zonal Gene Expression in Mouse Liver written by Albert Braeuning and published by Logos Verlag Berlin GmbH. This book was released on 2008 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hepatocytes located in the periportal or perivenous regions of the liver lobule have different, often complementary functions, as indicated by differences in the content and activity of various enzymes of the intermediary and xenobiotic metabolism. The signaling molecules mediating this metabolic zonation, however, are largely unknown. Based on the correlation of marker protein expression between perivenous hepatocytes and Ctnnb1 (encoding beta-catenin)-mutated mouse hepatomas and between periportal hepatocytes and Ha-ras-mutated hepatomas, a hypothesis was developed postulating that two opposing signals, a Wnt-signal maybe delivered by endothelial cells of the central veins activating a beta-catenin-dependent pathway, and a second signal delivered by blood-borne molecules activating Ras-dependent downstream cascades, regulate gene expression in hepatocytes from the periportal and perivenous domains of the liver lobule.The impact of beta-catenin and Ras signaling on zonal gene expression was analyzed in vivo by use of different transgenic mouse strains. Zone-specific physiological activation and antagonism of the two pathways were demonstrated. Transcriptome profiles of Ctnnb1- and Ha-ras-mutated tumors closely resembled those of perivenous and periportal hepatocytes. In vitro experiments with primary hepatocytes and hepatoma cells confirmed the role of beta-catenin signaling in the induction of "perivenous" gene expression, particularly of drug-metabolizing enzymes. Inducibility of drug-metabolizing enzymes by xenobiotics was demonstrated to be modulated by beta-catenin in vitro and in vivo. beta-catenin thereby activated transcription by both direct beta-catenin/ TCF-dependent and indirect mechanisms.Serum components were shown to inhibit beta-catenin-mediated transcription and to induce the expression of "periportal" markers. Serum-mediated inhibition of beta catenin signaling was not exclusively linked to Ras activation, but also to the action of different ligand-activated nuclear receptors, thus suggesting a complex interplay of different blood-borne molecules in the periportal repression of beta catenin signaling.In summary, the results favor the hypothesis that gene expression patterns in periportal and perivenous hepatocytes are regulated, at least in part, by Ras- and beta catenin-dependent signaling pathways. In the perivenous areas of the liver lobule, beta catenin seems to act as a master regulator of both basal and inducible expression of enzymes involved in the metabolism of drugs and xenobiotics.
Download or read book Molecular Pathology of Liver Diseases written by Satdarshan P. S. Monga and published by Springer Science & Business Media. This book was released on 2010-12-14 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellular and Molecular Pathology of the Liver is extensive, complex and ranges from the understanding the basic molecular mechanisms that dictate everything from liver homeostasis to liver disease. Molecular Pathology of the liver is complicated due to some of the important functions inherent and unique to the Liver, including its innate ability to regenerate and the multitude of functions it plays for the wellbeing of an organism. With all this in mind, Molecular Pathology of Liver Diseases is organized in different sections, which will coherently and cohesively present the molecular basis of hepatic physiology and pathology. The first two sections are key to understanding the liver anatomy and physiology at a cellular level and go on to define the molecular mechanics in various liver cell types. These sections also cover the existing paradigms in liver development, regeneration and growth. The next section is key to understanding the Molecular Pathology unique to liver diseases and associated phenotypes. The final sections are geared towards the existing knowledge of the molecular basis of many common and uncommon liver diseases in both neoplastic and non-neoplastic areas including pathologies associated with intra-hepatic and extra-hepatic biliary tree. Thus, this textbook is a one-stop reference for comprehending the molecular mechanisms of hepatic pathobiology. It is clearly unique in its format, readability and information and thus will be an asset to many in the field of Pathology and other disciplines.

Download or read book The Cell Biology of Stem Cells written by Eran Meshorer and published by Springer Science & Business Media. This book was released on 2011-01-11 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stem cells have been gaining a lot of attention in recent years. Their unique potential to self-renew and differentiate has turned them into an attractive model for the study of basic biological questions such as cell division, replication, transcription, cell fate decisions, and more. With embryonic stem (ES) cells that can generate each cell type in the mammalian body and adult stem cells that are able to give rise to the cells within a given lineage, basic questions at different developmental stages can be addressed. Importantly, both adult and embryonic stem cells provide an excellent tool for cell therapy, making stem cell research ever more pertinent to regenerative medicine. As the title The Cell Biology of Stem Cells suggests, our book deals with multiple aspects of stem cell biology, ranging from their basic molecular characteristics to the in vivo stem cell trafficking of adult stem cells and the adult stem-cell niche, and ends with a visit to regeneration and cell fate reprogramming. In the first chapter, “Early embryonic cell fate decisions in the mouse”, Amy Ralson and Yojiro Yamanaka describe the mechanisms that support early developmental decisions in the mouse pre-implantation embryo and the current understanding of the source of the most immature stem cell types, which includes ES cells, trophoblast stem (TS) cells and extraembryonic endoderm stem (XEN) cells.

Download or read book Intercellular Communication in Cancer written by Mustapha Kandouz and published by Springer. This book was released on 2015-11-20 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells are by nature compelled to live in groups. They develop dependence over signaling cues received from their microenvironment, in particular from other cells, whether of their own “kind” or of a different type. Therefore, communicating with these cells is a critical aspect of their behavior and fate, as they live and die normally or as they undergo disease-related pathological changes, with dramatic repercussions. In this book, we have asked expert researchers in the field of Intercellular Communication in Cancer to provide chapters on different aspects of interaction between neighboring cells, in the context of cancer diseases. We have specifically focused our efforts on membrane-to-membrane contact-based rather than growth factors-mediated modes of intercellular communications. The contributing authors provide an extensive overview of their respective area of specialization, with an in-depth discussion of the molecular mechanisms of cell-cell interactions, the impact on tumor progression and response to therapies, as well as the cancer diagnostic value of this scientific information. This book aims to introduce essential aspects of the normal and pathological cellular fate and homeostasis to both scientists and clinicians, and also to provide established researchers with an update on the novelties and future directions this expanding field is witnessing.
Download or read book Vitamin D written by H.F. DeLuca and published by Springer. This book was released on 2011-12-13 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because diseases of the bone are often less acute and less lifethreatening than dis eases of the circulatory system, gastrointestinal tract, kidney, liver, and the nervous system, they have received a disproportionately smaller amount of attention in the medical world. With the average increasing life span of man as a result of improve ments in modern medicine, espe~ially in the pediatric field, the seriousness of many metabolic bone diseases has indeed become more obvious. In addition, other improvements in medicine, such as hemodialysis for the preservation of renal failure patients, have permitted the development of other consequences of diseased kidneys, one of which is the appearance of renal osteodystrophy. Finally, the appearance of several genetic disorders in the area of metabolic bone disease has been underscored by the solution of other pediatric diseas~s of much more serious consequences. These emerging problems all suggest that much remains to be learned concerning the sys temic control of bone, both as a structural organ and as a reservoir for the important elements of calcium and phosphorus so essential for the support of life in complex multicellular organisms of which man is the most important. As will be demonstrated in the historical portion of this manuscript, the existence of the three most important humoral factors regulating bone metabolism and func tion are now known.
