This book was released on 2010 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our studies address early control points in the differentiation process that are necessary for expression as well as the maintenance of the adipocyte phenotype. We have focused on the post-transcriptional regulation of mRNA metabolism by the RNA binding protein HuR. Depending on the particular mRNA, HuR has been suggested to control polyadenylation, translocation to the cytosol, mRNA stability, and/or translational efficiency. Using the 3T3-L1 preadipocyte cell line, we have demonstrated a critical role for HuR in the differentiation process by use of siRNA mediated suppression which resulted in an inhibition of differentiation. We have identified several mRNAs that serve as HuR ligands early in the differentiation process, one of which is C/EBPβ, an important adipocyte transcription factor, whose expression is highly controlled and essential for proper acquisition of the adipocyte phenotype. Within minutes of induction of differentiation, HuR forms an mRNP complex with C/EBPβ mRNA in the nucleus followed by translocation to the cytoplasm. HuR remains associated with C/EBPβ mRNA suggesting a role in mRNA stability and translation efficiency. Our data suggest that formation of this complex in the nucleus serves as a regulator/attenuator of polyadenylation and that this interaction leads to a controlled metabolism of the C/EBPβ mRNA by determination of the quantity of message translocated to the cytosol and available for translation. Additionally, our data have directed us toward the Zfp206 mRNA as an important HuR ligand whose regulation is predicted to be responsible for maintenance of the differentiation potential of the cells and whose expression is terminated as the cells express PPARγ and establish the adipocyte phenotype. Our mechanistic analysis of these issues will identify novel control points in the initial stages of adipogenesis and thus fundamental to the pathological states of obesity and diabetes.

Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Cellular Quiescence: Methods and Protocols offers a broad view of basic and cutting-edge technology to inspire research in this emerging field of cell biology.
Book Synopsis Animal and Human Calorimetry by : J. A. McLean
Download or read book Animal and Human Calorimetry written by J. A. McLean and published by Cambridge University Press. This book was released on 2007-12-03 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive survey of the theory, practice, and techniques of calorimetry as applied to the study of energy metabolism in humans and animals. Calorimetry is used to estimate nutritional requirements of man and farm livestock and to evaluate different foods. It is also a powerful tool used in research into fundamental nutritional and physiological life processes and in the evaluation of stresses imposed by abnormal or severe environments. It is currently being applied in various branches of medical research and can be used as a diagnostic tool in hospitals for investigation of metabolic disorders. The authors discuss both direct calorimetry, which measures heat loss directly, and indirect calorimetry, where heat loss is inferred by measurement of some of the chemical byproducts of metabolism. In addition, guidance is provided to the instrumentation, technical problems, and precautions necessary to obtain accurate calorimetric measurements.
Book Synopsis Handbook of Nutrition, Diet, and Epigenetics by : Vinood B. Patel
Download or read book Handbook of Nutrition, Diet, and Epigenetics written by Vinood B. Patel and published by Springer. This book was released on 2019-02-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multivolume reference work addresses the fact that the well being of humankind is predicated not only on individuals receiving adequate nutrition but also on their genetic makeup. The work includes more than 100 chapters organized in the following major sections: Introduction and Overview; Epigenetics of Organs and Diseases in Relation to Diet and Nutrition; Detailed Processes in Epigenetics of Diet and Nutrition; Modulating Epigenetics with Diet and Nutrition; and Practical Techniques. While it is well known that genes may encode proteins responsible for structural and dynamic components, there is an increasing body of evidence to suggest that nutrition itself may alter the way in which genes are expressed via the process of epigenetics. This is where chemically imposed alteration in the DNA sequence occurs or where the functional expression of DNA is modulated. This may include changes in DNA methylation, non-coding RNA, chromatin, histone acetylation or methylation, and genomic imprinting. Knowledge regarding the number of dietary components that impact on epigenetic processes is increasing almost daily. Marshalling all the information on the complex relationships between diet, nutrition, and epigenetic processes is somewhat difficult due to the wide myriad of material. It is for this reason that the present work has been compiled.

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 and published by Springer Science & Business Media. This book was released on 2013-05-22 with total page 370 pages. 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.
