This book was released on 2010 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The neural crest is a remarkable embryonic population of cells found only in vertebrates and has the potential to give rise to many different cell types contributing throughout the body. These derivatives range from the mesenchymal bone and cartilage comprising the facial skeleton, to neuronal derivatives of the peripheral sensory and autonomic nervous systems, to melanocytes throughout the body, and to smooth muscle of the great arteries of the heart. For these cells to correctly progress from an unspecifi ed, nonmigratory population to a wide array of dynamic, differentiated cell types-some of which retain stem cell characteristics presumably to replenish these derivatives-requires a complex network of molecular switches to control the gene programs giving these cells their defi ning structural, enzymatic, migratory, and signaling capacities. This review will bring together current knowledge of neural crest-specifi c transcription factors governing these progressions throughout the course of development. A more thorough understanding of the mechanisms of transcriptional control in differentiation will aid in strategies designed to push undifferentiated cells toward a particular lineage, and unraveling these processes will help toward reprogramming cells from a differentiated to a more naive state.

This book was released on 2012-12-06 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is of critical importance to maintain an appropriate balance between proliferation and quiescence or differentiation through out the lifespan of all animals. An important control point in this balance occurs in the G, phase of the cell cycle. On the basis of environmental cues a cell in G, must decide whether to continue through the proliferative cycle and enter S phase (where DNA replication occurs) or to exit from the proliferative cycle into a nonreplicating state. Alterations in the mechanisms that nor mally control this decision can lead to cancer, cell death, or loss of differentiated cellular phenotypes. The identification of the E2F gene family of transcription factors has allowed a more complete understanding of how the cell maintains an appropri ate proliferative state. This volume provides an up-to-date ac count of present reports concerning E2F as well as a framework for future investigations. E2F activity requires heterodimerization of two partners. Either partner can be one of several different transcription factors; E2Fl, E2F2, E2F3, E2F4, or E2F5 can heterodimerize with either DPl or DP2. Cellular promoters whose E2F sites mediate a link between transcription and proliferation drive genes whose products are required for DNA synthesis and genes that encode regulators of cell growth. A detailed analY$is of the role that E2F family members play in transcription from these promoters is presented in the chapter by J. E. SLANSKY and P. J. FARNHAM.

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.

This book was released on 2012-12-06 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: A recent volume of this series (Signals and Signal Transduction Pathways in Plants (K. Palme, ed.) Plant Molecular Biology 26, 1237-1679) described the relay races by which signals are transported in plants from the sites of stimuli to the gene expression machinery of the cell. Part of this machinery, the transcription apparatus, has been well studied in the last two decades, and many important mechanisms controlling gene expression at the transcriptional level have been elucidated. However, control of gene expression is by no means complete once the RNA has been produced. Important regulatory devices determine the maturation and usage of mRNA and the fate of its translation product. Post-transcriptional regulation is especially important for generating a fast response to environmental and intracellular signals. This book summarizes recent progress in the area of post-transcriptional regulation of gene expression in plants. 18 chapters of the book address problems of RNA processing and stability, regulation of translation, protein folding and degradation, as well as intracellular and cell-to-cell transport of proteins and nucleic acids. Several chapters are devoted to the processes taking place in plant organelles.

Download or read book Epigenetic and Transcriptional Control of the Caulobacter Cell Cycle written by Jennifer Leigh Boyd Kozdon and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In order for a cell to propagate, numerous events must be coordinated spatially and temporally within the cell. Caulobacter crescentus, an [alpha]-proteobacterium that divides asymmetrically, employs many layers of control such as phospho-relay systems, protein localization, targeted proteolysis, epigenetic regulation, and transcriptional regulation to achieve this spatial and temporal coordination over its cell cycle. This work focuses on two of these layers: the epigenetic role of the CcrM DNA methyltransferase and the regulatory roles of the GcrA and SciP transcription factors. The timing of transcriptional activation of at least four essential Caulobacter genes is affected by the methylation state of GANTC sites in their promoters. To explore the global scope of this regulatory mechanism, we determined the methylation state of the entire genome over the cell cycle (Chapter 2). This led to the identification of four novel methylation motifs in addition to the previously characterized CcrM methyltransferase motif. Only the GANTC motif which is methylated by CcrM exhibited a dynamic methylation pattern, shifting from fully methylated to hemi-methylated concomitant with replication fork passage. Using these cell cycle-dependent methylation profiles of GANTC sites as well as gene expression data from synchronized cell populations, we identified candidate genes whose transcription might be affected by the methylation state of their promoters. In addition, 27 GANTC sites were found to be unmethylated throughout the cell cycle. In Chapter 3, we used DNA footprinting to show that the GcrA transcription factor contains an N-terminal helix-turn-helix domain that binds DNA between the -10 and -35 promoter elements of three genes: podJ, parE, and ctrA. Each of the three footprinted regions contains a GANTC methylation site. Furthermore, we demonstrated through ChIP-qPCR that GcrA binds these sites in vivo. Mutations in these GcrA-binding regions reduced promoter activity, indicating that GcrA binding at these sites is important for activity. Finally, in Chapter 4, we identified a novel set of signaling pathways in the cell cycle network established by the SciP transcription factor, and we show that SciP binds DNA and identified its binding motif. At least 58 genes are in the SciP regulon, including many flagellar and chemotaxis genes. The SciP transcription factor functions to repress ctrA and CtrA target genes, restricting the expression of these genes to a precise time in the cell cycle when CtrA is available but SciP is not, and thus enhances the robustness of the Caulobacter cell cycle. This work expands our understanding of the master regulatory network that is involved in controlling the Caulobacter cell cycle. In addition, it describes the global methylation state of each base in the chromosome as a function of the cell cycle which will facilitate the discovery of novel methylation-mediated regulatory mechanisms in Caulobacter.
