This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolutionary conserved insulin and nutrient signaling network regulates growth andmetabolism. Nutrients are directly utilized for growth or stored, mostly as triglycerides. InDrosophila, activation of insulin/nutrient signaling in the fat body (the fly equivalent of liverand adipose tissue), causes an increase in fat stores composed of several small-size lipiddroplets (LDs). Conversely, fasting produces an increase in LD size and a decrease in fatcontents. The TOR kinase and its substrate S6 kinase (S6K) play a central role in this response,and particularly in Drosophila, they have been shown to orchestrate cell-autonomous andhormone-controlled growth. However, despite extensive research studies on different modelorganisms (mouse, fly, worm) to decipher the molecular and physiological functions of S6K,nothing is known about how its degradation is regulated.Taking advantage of the inducible RNA interfering (RNAi) library from NIG (Japan), we haveperformed three genetic screens to identify novel regulators of steroidogenesis, lipidmetabolism and dS6K-dependent growth. First, RNAi lines were screened in the ring gland; anorgan that controls the progression of the developmental steps by producing the steroidhormone ecdysone. Out of 7,000 genes screened, 620 positive candidates were identified toproduce developmental arrest and/or overgrowth phenotypes. Then, we challenged 4,000 genesby RNAi screening able to recapitulate the larger sized LD phenotype as obtained uponstarvation, leading to the identification of 24 potential candidates. Finally, the RNAi lines werescreened for their ability to enhance a growth phenotype dependent of the Drosophila S6K(dS6K). Out of 7,000 genes screened, 45 genes were identified as potential negative regulatorsof dS6K. These genes were further used to design a novel protein-protein interaction networkcentered on dS6K through the available data from yeast-2-hybrid (Y2H) assay. The most potentinteractors were then analyzed by treatment of cultured S2 cells with the corresponding doublestrand RNA (dRNA). Western blotting thus, allowed us to discriminate between the geneproducts that regulate dS6K levels versus those that regulate its phosphorylation, as a hallmarkfor its kinase activity. Interestingly, archipelago (ago), which encodes a component of an SCFubiquitinligase known to regulate the degradation of dMyc, Cyclin E and Notch, was identifiedas a negative regulator of dS6K-dependent growth. Based on the Y2H available data showingthat Ago and dS6K interact each other and the presence of a putative Ago-interaction motif indS6K, we hypothesized that Ago causes an ubiquitin-mediated degradation of dS6K. Ourmolecular data showed that loss of ago caused an elevated level of dS6K, which confirms arole of Ago in controlling dS6K degradation. Altogether our findings emphasize the importanceof the saturating screening strategies in Drosophila to identify novel regulators of metabolicand signaling pathways.

Download or read book Recent Trends in Gene Expression written by Subhrangsu S. Mandal and published by Nova Science Publishers. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term Gene refers to a segment of DNA present inside the genome that code for a protein. Depending on the organism, a particular genome may encode thousands of diverse types of genes responsible for various functions. These genes are differentially expressed and tightly regulated as needed at different stages of cell and physiological functions including cell differentiation and development. Gene expression may be influenced by various environmental and stimuli such as temperature, nutrients, hormones, stress etc. Though the fundamental mechanism of transcription (production of mRNA from the protein coding genes) is very similar in different organisms, the mechanism of gene regulation and the machineries involved are distinct for different organisms. In the post genomic and epigenomic era, it is increasingly being recognised that gene expression is not only controlled gene sequences but also various other non-genomic factors that include protein and DNA modifications and non-coding RNAs.Various aspects of gene expression in prokaryotes and eukaryotes, the mechanism of transcription and gene regulation and influences of various environmental factors are highlighted in different chapters of this book.

Available in PDF, EPUB and Kindle. Book excerpt: Inborn Disorders of Sphingolipid Metabolism is a collection of papers presented at the Third International Symposium on the Cerebral Sphingolipidoses and Allied Diseases, held at the Isaac Albert Research Institute of the Jewish Chronic Disease Hospital and at the State University of New York, Downstate Medical Center, on October 25 and 26, 1965. This book is organized into three parts encompassing 35 chapters. Part I deals first with electron microscopic, histochemical, and morphological investigations of certain sphingolipid metabolism disorders. This part also examines several case reports on the features and symptoms of spongy degeneration of the central nervous system, familial leukodystrophy, adrenal insufficiency, and cutaneous melanosis. Part II surveys the metabolism, biosynthesis, and structure of gangliosides and sialic acids. This part also considers the nature of the lipophilic portions of the brain gangliosides. This part particularly looks into the features and clinical manifestation of Tay-Sachs disease. The third part covers the genetic and clinical aspects of the Tay-Sachs disease. This part also evaluates the genetics of the Hurler-Hunter syndrome, Batten-Spielmeyer-Vogt disease, and lipogranulomatosis syndrome. This book is of value to biochemists, histochemists, geneticists, and researchers in the allied fields of lipidosis.

Available in PDF, EPUB and Kindle. Book excerpt: "One of the most productive of all laboratory animals, Drosophila has been a key tool in genetics research for nearly a century. At the center of Drosophila culture from 1910 to 1940 was the school of Thomas Hunt Morgan and his students Alfred Sturtevant and Calvin Bridges, who, by inbreeding fruit flies, created a model laboratory creature - the 'standard' fly. By examining the material culture and working customs of Morgan's research group, [the author] brings to light essential features of the practice of experimental science. [This book] takes a broad view of experimental work, ranging from how the fly was introducted into the laboratory and how it was physically redesigned for use in genetic mapping, to how the 'Drosophilists' organized an international network for exchanging fly stocks that spread their practices around the world"--Back cover.
