Available in PDF, EPUB and Kindle. Book excerpt: Biological processes are driven by complex systems of functionally interacting signaling molecules. Thus, understanding signaling molecules is essential to explain normal or pathological biological phenomena. A large body of clinical and experimental data has been accumulated over these years, albeit in fragmented state. Hence, systems biological approaches concomitant with the understanding of each molecule are ideal to delineate signaling networks/pathways involved in the biologically important processes. The control of these signaling pathways will enrich our healthier life. Currently, there are more than 30,000 genes in human genome. However, not all the proteins encoded by these genes work equally in order to maintain homeostasis. Understanding the important signaling molecules as completely as possible will significantly improve our research-based teaching and scientific capabilities. This encyclopedia presents 350 biologically important signaling molecules and the content is built on the core concepts of their functions along with early findings written by some of the world’s foremost experts. The molecules are described by recognized leaders in each molecule. The interactions of these single molecules in signal transduction networks will also be explored. This encyclopedia marks a new era in overview of current cellular signaling molecules for the specialist and the interested non-specialist alike During past years, there were multiple databases to gather this information briefly and very partially. Amidst the excitement of these findings, one of the great scientific tasks of the coming century is to bring all the useful information into a place. Such an approach is arduous but at the end will infuse the lacunas and considerably be a streamline in the understanding of vibrant signaling networks. Based on this easy-approach, we can build up more complicated biological systems.

Download or read book Cancer Cell Structures Carcinogens and Genomic Instability written by Leon P. Bignold and published by Springer Science & Business Media. This book was released on 2006 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tumors can be induced by a variety of physical and chemical carcinogens. The resulting tumor cells are usually abnormal in their morphology and behavior and transmit their abnormalities to their daughter tumor cells. Most theories of the pathogenesis of tumors suggest that carcinogens in some way cause alterations either of the genomes or of inheritable patterns of gene expression in normal cells, which then cause morphological and behavioral changes. This volume presents a collection of articles aimed at the question by what genetic or epigenetic mechanisms carcinogens can cause morphological abnormalities of tumor cells. It includes reviews of cellular targets of known carcinogens, and presents varying viewpoints of how morphological abnormalities and the actions of carcinogens might be related. The volume will be of interest to all those who are involved in cancer research or in the prevention, diagnosis or management of tumors in humans or animals.

This book was released on 2009-03-04 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stem cells appear to be fundamental cellular units associated with the origin of multicellular organisms and have evolved to function in safeguarding the cellular homeostasis in organ t- sues. The characteristics of stem cells that distinguish them from other cells have been the fascinating subjects of stem cell research. The important properties of stem cells, such as ma- tenance of quiescence, self-renewal capacity, and differentiation potential, have propelled this exciting ?eld and presently form a common theme of research in developmental biology and medicine. The derivation of pluripotent embryonic stem cells, the prospective identi?cation of multipotent adult stem cells, and, more recently, the induced pluripotent stem cells (popularly called iPS) are important milestones in the arena of stem cell biology. Complex networks of transcription factors, different signaling molecules, and the interaction of genetic and epi- netic events constantly modulate stem cell behavior to evoke programming and reprogramming processes in normal tissue homeostasis during development. In any given cellular scenario, the regulatory networks can pose considerable complexity and yet exert an orderly control of stem cell differentiation during normal development. An aberration in these ?nely tuned processes during development usually results in a spectrum of diseases such as cancers and neurological disorders.

Download or read book The Role of SOX2 in Human Embryonic Stem Cells written by Helen Fong and published by . This book was released on 2011 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: SOX2 is a transcription factor critical for maintenance of the stem cell state. It plays a major role in the development of the central nervous system (CNS), as it is required for the proliferation and maintenance of neural stem cells as well as neurogenesis. In this work, I show that SOX2 is a crucial factor for the maintenance of pluripotency and self-renewal in hES cells and further elucidate its role in the regulation of the survival gene, TRKC. I also present evidence that SOX2 can interact with the POU transcription factor OCT1 in the regulation of TRKC, demonstrating a novel SOX2 protein-protein interaction in human embryonic stem (hES) cells. By using siRNA to reduce levels of SOX2 expression, I find that loss of SOX2 significantly affects the morphology of hES cells as well as downregulates markers of pluripotent hES cells, OCT4, TRA-1-81, SSEA-3, and SSEA-4. In addition to reducing SOX2 levels, I knocked down expression of OCT4 and NANOG and find that the expression of the three factors depends on each other to maintain the stem cell state. Loss of SOX2 also causes hES cells to differentiate into trophectoderm, as well as affect a number of downstream target genes, which may be important for the stem cell state. I also demonstrate that SOX2 can regulate the TRKC gene, a gene important for the survival of single hES cells. Through RNAi of SOX2, I found the expression of TRKC to be significantly downregulated indicating that SOX2 has a regulatory effect on TRKC gene expression. SOX2 is able to physically bind to a particular SOX2 binding motif on the regulatory region of the gene and efficiently drive expression. I also present data that suggests SOX2 can interact with the OCT1 transcription factor to possibly regulate TRKC. This data is novel in hES cells, indicating that there may be many undiscovered interactions between SOX2 and other transcription factors.

Download or read book Genome Binding and Gene Regulation by Stem Cell Transcription Factors written by and published by . This book was released on 2016 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly all cells of an individual organism contain the same genome. However, each cell type transcribes a different set of genes due to the presence of different sets of cell type-specific transcription factors. Such transcription factors bind to regulatory regions such as promoters and enhancers and regulate their activity in gene transcription. Transcription factors interact with each other and form tissue-specific transcription factor networks. Identification of genome binding and gene regulation by transcription factors will enhance our understanding of how transcription factors specify cell types. Chapter 1 serves as a general introduction into eukaryotic transcription regulation and describes the role of enhancers and transcription factors. Chapters 2 - 4 describe the experimental work of this thesis. Chapter 2 describes Chromatin Immunoprecipitation followed by Mass Spectrometry (ChIP-MS), a technique used to identify transcription factors and other genome binding proteins that bind to promoters, enhancers or heterochromatin. Chapter 2 specifically describes the genome-binding pattern of transcription- and pluripotency factor Dppa2, which we identify by ChIP-MS and ChIP-seq to bind to promoters outside the classical pluripotency network. Chapter 3 describes a transcription factor interaction network of over 200 proteins in neural stem cells, which was assembled by the identification of interaction partners of four mental disorder-associated transcription factors. Chapter 4 describes work on the genome-wide localization of Oct4, Sox2 and Nanog in embryonic stem cells and investigates the genome localization of these transcription factors upon depletion of Oct4 or Sox2 from embryonic stem cells. The last chapter, Chapter 5, summarizes the results from Chapter 2-4 and provides additional discussion to these chapters, concerning its implications and future directions.
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.
