Available in PDF, EPUB and Kindle. Book excerpt: Epithelial cells cover the outer and inner surfaces of the body, forming a selective polarized barrier between the intercellualar space and the 'external' world. Linking the cells of this continuous layer and contributing to epithelial organization and function are specialized membrane domains--desmosomes, gap junctions, and occluding junctions. The contributors to this multidisciplinary symposium volume explore the nature of such junctional structures, focusing on the molecular organization and diversity of their constituent proteins, their formation and control, and interactions with ions and cytoskeletal elements. The physiological significance of cell-cell interaction in epithelia is considered, with reference to cell adhesion, barrier formation and intercellular communication, and to the functional implications for tissue architecture, embryonic development, morphogenesis and carcinogenesis.

This book was released on 2009-06-22 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aim of this volume is to clarify the relationship between molecular structure and function of tight junction proteins, as well as their regulation and their role in diseases. Current research may form a basis for future diagnostic and therapeutic approaches to diseases which seem to have not much in common but are characterized by defects of organ barriers, like Crohn's disease, renal hypertension, inner ear deafness, and cancerous diseases. Topics include the functions of distinct tight junction proteins as barrier or channel formers for solutes and water, characteristics of the tight junction in inflammatory bowel diseases, posttranslational modifications of tight junction proteins, the relation between renal tight junction proteins and blood pressure control, and the molecular structure of claudin-claudin interactions NOTE: Annals volumes are available for sale as individual books or as a journal.

Download or read book Adherens Junctions from Molecular Mechanisms to Tissue Development and Disease written by Tony J C Harris and published by Springer. This book was released on 2012-06-08 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell–cell adhesion is fundamental for the development and homeostasis of animal tissues and organs. Adherens junctions (AJs) are the best understood cell-cell adhesion complexes. In this volume, a group of internationally recognized experts reviews AJ biology over a wide range of organization; from atoms to molecules, to protein complexes, molecular networks, cells, tissues, and overall animal development. AJs have also been an integral part of animal evolution, and play central roles in cancer development, pathogen infection and other diseases. This book addresses major questions encompassing AJ biology. • How did AJs evolve? • How do cadherins and catenins interact to assemble AJs and mediate adhesion? • How do AJs interface with other cellular machinery to couple adhesion with the whole cell? • How do AJs affect cell behaviour and multicellular development? • How can abnormal AJ activity lead to disease?
Download or read book Molecular Mechanisms of Epithelial MLCK Isoform Regulation Characterization and Pharmacological Exploitation written by W. Vallen Graham and published by . This book was released on 2010 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: The molecular events surrounding TNF-mediated tight junction regulation are the focus of this dissertation. Exposure of cultured epithelial monolayers to TNF in vitro can cause barrier loss. This tight junction regulation occurs within hours and is mediated by myosin light chain kinase (MLCK), which phosphorylates myosin II regulatory light chain (MLC). The mechanisms by which TNF activates MLCK may include initiation of an increase in intracellular Ca2+, but this has not been reported in intestinal epithelium. However, it is clear that TNF induces transcriptional activation of MLCK, both in human intestinal epithelial cell lines in vitro and in mouse enterocytes in vivo. Moreover, this process appears to be active in human inflammatory bowel disease patients in vivo, as intestinal epithelial MLCK expression and MLC phosphorylation are both increased in association with active disease. The data discussed here describe the molecular events in MLCK transcriptional activation and the novel observation that MLCK1 is trafficked to the perijunctional actomyosin ring in response to TNF signaling. Furthermore, I describe here, unique tools for studying MLCK1 trafficking and activity. Targeting MLCK1-specific trafficking with small molecule drugs reverses TNF-induced barrier dysfunction in vitro and in vivo. Therefore, not only are these drugs powerful tools in understanding molecular mechanisms that regulate MLCK1, but may also represent a therapeutic alternative to the current IBD treatment regimen of immune suppression.
Download or read book Role of Translation Initiation in Regulation of Epithelial Junctions and Cell Motility written by Fahda Fawaz Alsharief and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The integrity and barrier properties of intestinal epithelium are determined by specialized adhesive structures known as intercellular junctions; composed of adherens junctions (AJs), tight junctions (TJs) and focal adhesions that mediate cell-cell and cell matrix interactions, respectively. These two types of epithelial cell adhesions regulate each other during disruption and restitution of the epithelial barrier. Inflammatory cytokines such as interferon gamma (IFN[gamma]) and tumor necrosis factor alpha (TNF[alpha]) are elevated during intestinal inflammation. The most notable effects of IFN[gamma] and TNF[alpha] on intestinal epithelial homeostasis involve disruption of apical junctions and attenuation of cell migration. Although molecular mechanisms underlying these effects remain poorly understood, expressional downregulation of different adhesion proteins may play a major role in the cytokine-dependent disruption of the intestinal epithelial barriers. This thesis is based on the hypothesis that inhibition of the protein translation initiation machinery promotes the disruption of the intestinal epithelial barrier and attenuates epithelial restitution during mucosal inflammation. This study was focused on two eukaryotic translation initiation factors, eIF4G1 and eIF4G2, which play essential roles in the regulation of cap-dependent protein translation. Expression of both translation initiation factors was dramatically downregulated in model intestinal epithelial cell monolayers treated with IFNÎđ and TNF[alpha] in parallel to cytokine-induced disruption of the epithelial barrier. siRNA or shRNA-mediated downregulation of either eIF4G1, or eIF4G2 increased permeability of well-differentiated SK-CO15 intestinal epithelial cell monolayers and decreased expression of different adherens junction and tight junction proteins. Furthermore depletion of these translation initiating factors inhibits different modes of migration (wound healing and transfilter migration) of stem-cell like and well-differentiated intestinal epithelial cells. These findings suggest that eukaryotic translation initiation factors of the eIF4G family play unique roles in regulating integrity and restitution of the intestinal epithelial barrier. Downregulation of these translation initiating factors may mediate disruption of the intestinal epithelial barriers during mucosal inflammation.

Download or read book Tight Junctions in Cancer Metastasis written by Tracey A. Martin and published by Springer Science & Business Media. This book was released on 2013-02-26 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a dramatic increase in knowledge of tight junctions in the past decade. The molecular structure of tight junctions, cellular functions and the pathophysiological roles of tight junctions are becoming clear. Of the most important functions, the role of the cellular structure in cancer spread and drug delivery are increasingly realised. It is now clear that there are fundamental changes to tight junctions during the process of cancer development. Tight junctions are also critical to the metastatic process of cancer cells. The cellular structure is also crucial in drug therapies, namely, the permeability and bioavailability of the drugs, penetration of barriers such as the blood brain barrier. This current volume aims to summarise the current knowledge of tight junctions, their role in cancer and cancer metastasis and is of interest to scientists and clinicians.

Download or read book Regenerative Nephrology written by Michael S. Goligorsky and published by Academic Press. This book was released on 2010-11-26 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progression of chronic diseases in general and chronic kidney disease in particular has been traditionally viewed in the light of various contributors to development of glomerulosclerosis and tubulointerstitial scarring culminating in renal fibrosis. Indeed, this dogma prevailed for decades underscoring experimental attempts to halt fibrotic processes. Breakthrough investigations of the past few years on stem/progenitor cell involvement in organ regeneration caused a conceptual shift in tackling the mechanisms of nephrosclerosis. It has become clear that the rate of progression of chronic kidney disease is the net sum of the opposing trends: degenerative fibrotic processes and regenerative repair mechanisms. The latter part of this equation has been by and large ignored for years and only recently attracted investigative attention. This book revisits the problem of kidney disease by focusing on regenerative mechanisms in renal repair and on the ways these regenerative processes can become subverted by an intrinsic disease process eventuating in its progression. Cutting-edge investigations are summarized by the most experienced international team of experts. Presents a comprehensive, translational source for all aspects of renal stem cells, tissue regeneration, and stem cell therapies for renal diseases in one reference work. This will ultimately result in time savings for academic, medical and pharma researchers Experts in the renal stem cell system in kidney repair and regeneration take readers from the bench research to new therapeutic approaches, providing a common language for nephrology researchers, fellows and other stem cell researchers. This enables the discussion of development of stem cells and their use in the repair and regeneration of the kidney
Download or read book Biology of the Integument written by J. Bereiter-Hahn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 858 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integument plays an important role in the survival of meta zoans by separating and protecting them from a hostile environ ment. Its function ranges from protection against injury and in fection; partlcipation in the regulation of body temperature and water balance, to respiratory activity, monitoring of the environ ment and production of signals related to behaviour. All these result from specific structural, biochemical and physiological properties of intra-and extracellular components of the integu ment. Thus its characterization can be best accomplished by a multidisciplinary approach with authors specialized in different fields of science. This multi-author book, in two volumes, provides an up-to date survey of the literature. The first volume deals with the integument of invertebrates, the second with that of vertebrates, both organized primarily on a phylum basis. As the level of knowledge on the integument of phyla differs considerably, the information provided is correspondingly either limited or con densed. For some of the smaller groups of invertebrates little information is available, as often only a few electron micrographs are to be found in the literature; on the other hand, from the large body of knowledge existing for vertebrates, particularly for mammals, no complete overview can be provided, but publica tions giving access to further information have been reviewed critically.
