Book Synopsis Transcriptional and Translational Regulation of Stem Cells by : Gary Hime

Download or read book Transcriptional and Translational Regulation of Stem Cells written by Gary Hime. This book was released on 2013-05-22. Available in PDF, EPUB and Kindle. Book excerpt: This volume describes the latest findings on transcriptional and translational regulation of stem cells. Both transcriptional activators and repressors have been shown to be crucial for the maintenance of the stem cell state. A key element of stem cell maintenance is repression of differentiation factors or developmental genes – achieved transcriptionally, epigenetically by the Polycomb complex, and post-transcriptionally by RNA-binding proteins and microRNAs. This volume takes two approaches to this topic – (1) illustrating the general principles outlined above through a series of different stem cell examples – embryonic, iPS and adult stem cells, and (2) describing several molecular families that have been shown to have roles in regulation of multiple stem cell populations.

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.

Book Synopsis Transcriptional and Translational Control in Cell Fate Determination by : Soroush Tahmasebi

Download or read book Transcriptional and Translational Control in Cell Fate Determination written by Soroush Tahmasebi. This book was released on 2011. Available in PDF, EPUB and Kindle. Book excerpt: Multi-cellular organisms generate functional and morphological diversity in their cells through spatiotemporal regulation of gene expression. Gene expression is regulated through multiple mechanisms at the levels of transcription, translation, and degradation. During my PhD studies, I examined transcription factor-induced somatic-to-induced pluripotent stem cell reprogramming. For this, I adopted two different strategies that are based on transcriptional regulation by post-translational modification and translational control by the translational repressor 4E-BP. Specifically, in the project described in Chapter III, I studied the role of sumoylation in controlling the transcriptional activity of KLF4, KLF2, and KLF5 during reprogramming and adipocyte differentiation. I also explored the role of Ubc9, the sole SUMO-conjugating enzyme, in reprogramming and adipogenesis. These results and a comprehensive review of related studies, presented in Chapter I, have ...
