Description: Platelets are the second most abundant cell type in blood and are essential for maintaining haemostasis. Their count and volume are tightly controlled within narrow physiological ranges, but there is only limited understanding of the molecular processes controlling both traits. Here we carried out a high-powered meta-analysis of genome-wide association studies (GWAS) in up to 66,867 individuals of European ancestry, followed by extensive biological and functional assessment. We identified 68 genomic loci reliably associated with platelet count and volume mapping to established and putative novel regulators of megakaryopoiesis and platelet formation. These genes show megakaryocyte-specific gene expression patterns and extensive network connectivity. Using gene silencing in Danio rerio and Drosophila melanogaster, we identified 11 of the genes as novel regulators of blood cell formation. Taken together, our findings advance understanding of novel gene functions controlling fate-determining events during megakaryopoiesis and platelet formation, providing a new example of successful translation of GWAS to function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3335296/" target="_blank"〉〈img

Description: The endoplasmic reticulum (ER) contains molecular chaperones that facilitate the folding of proteins in mammalian cells. Biosynthetic labeling was used to study the interactions of two chaperones, BiP and calnexin, with vesicular stomatitis virus (VSV) glycoprotein (G protein). Coimmunoprecipitation of G protein with the chaperones showed that BiP bound maximally to early folding intermediates of G protein, whereas calnexin bound after a short lag to more folded molecules. Castanospermine, an inhibitor of ER glucosidases, blocked the binding of proteins to calnexin and inhibited G protein folding. Interaction with calnexin was necessary for efficient folding of G protein and for retention of partially folded forms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hammond, C -- Helenius, A -- P01 CA46128/CA/NCI NIH HHS/ -- R01 GM38346/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Oct 21;266(5184):456-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Yale University School of Medicine, New Haven, CT 06510.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7939687" target="_blank"〉PubMed〈/a〉

Description: 3-Methylindole, a ruminal fermentation product of tryptophan, induces acute pulmonary edema and emphysema in cattle, and 3-methylindole is present in the ruminal fluid and blood of cows with a natually occurring form of this disease. Monensin, a polyether antibiotic and widely used feed additive for beef cattle, prevented tryptophan-induced acute bovine pulmonary edema and emphysema. Monensin acted by reducing the ruminal conversion of L-tryptophan to 3-methylindole both in vitro and in vivo. Lasalocid, also a polyether antibiotic, showed similar effects in vitro. These results provide a promising approach to prevention of this major respiratory disease of cattle.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hammond, A C -- Carlson, J R -- Breeze, R G -- New York, N.Y. -- Science. 1978 Jul 14;201(4351):153-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/663643" target="_blank"〉PubMed〈/a〉
