Endothelin is synthesized in vascular endothelial and smooth muscle cells, as well as in neural, renal, pulmonic, and inflammatory cells. It acts through a seven transmembrane endothelin receptor A (ETA) and endothelin receptor B (ETB) receptors belongs to G protein-coupled rhodopsin-type receptor superfamily. This peptide involved in pathogenesis of cardiovascular disorder like (heart failure, arterial hypertension, myocardial infraction and atherosclerosis), renal failure, pulmonary arterial hypertension and it also involved in pathogenesis of cancer. Potentially endothelin receptor antagonist helps the treatment of the above disorder. Currently, there are a lot of trails both per-clinical and clinical on endothelin antagonist for various cardiovascular, pulmonary and cancer disorder. Some are approved by FAD for the treatment. These agents are including both selective and non-selective endothelin receptor antagonist (ETA/B). Currently, Bosentan, Ambrisentan, and Macitentan approved -

Receptor-Mediated Dimerization of JAK2 FERM Domains Is Required for JAK2 Activation Ryan D Ferrao, Heidi JA Wallweber, Patrick J Lupardus*
RESEARCH ARTICLE Receptor-mediated dimerization of JAK2 FERM domains is required for JAK2 activation Ryan D Ferrao, Heidi JA Wallweber, Patrick J Lupardus* Department of Structural Biology, Genentech, Inc., South San Francisco, United States Abstract Cytokines and interferons initiate intracellular signaling via receptor dimerization and activation of Janus kinases (JAKs). How JAKs structurally respond to changes in receptor conformation induced by ligand binding is not known. Here, we present two crystal structures of the human JAK2 FERM and SH2 domains bound to Leptin receptor (LEPR) and Erythropoietin receptor (EPOR), which identify a novel dimeric conformation for JAK2. This 2:2 JAK2/receptor dimer, observed in both structures, identifies a previously uncharacterized receptor interaction essential to dimer formation that is mediated by a membrane-proximal peptide motif called the ‘switch’ region. Mutation of the receptor switch region disrupts STAT phosphorylation but does not affect JAK2 binding, indicating that receptor-mediated formation of the JAK2 FERM dimer is required for kinase activation. These data uncover the structural and molecular basis for how a cytokine-bound active receptor dimer brings together two JAK2 molecules to stimulate JAK2 kinase activity. DOI: https://doi.org/10.7554/eLife.38089.001 Introduction Janus kinases (JAKs) are a family of multi-domain non-receptor tyrosine kinases responsible for pleio- tropic regulatory effects on growth, development, immune and hematopoietic signaling (Leonard and O’Shea, 1998). The JAK family consists of four conserved members, including JAK1, *For correspondence: [email protected] JAK2, JAK3, and TYK2, which are differentially activated in response to cytokine and interferon stim- ulation.

Differential Gene Expression in Oligodendrocyte Progenitor Cells, Oligodendrocytes and Type II Astrocytes

China 4Department of Laboratory Medicine, Bengbu Medical College, Bengbu, P.R. China Oligodendrocyte precursor cells (OPCs) are bipotential progenitor cells that can differentiate into myelin-forming oligodendrocytes or functionally undetermined type II astrocytes. Transplantation of OPCs is an attractive therapy for demyelinating diseases. However, due to their bipotential differentiation potential, the majority of OPCs differentiate into astrocytes at transplanted sites. It is therefore important to understand the molecular mechanisms that regulate the transition from OPCs to oligodendrocytes or astrocytes. In this study, we isolated OPCs from the spinal cords of rat embryos (16 days old) and induced them to differentiate into oligodendrocytes or type II astrocytes in the absence or presence of 10% fetal bovine serum, respectively. RNAs were extracted from each cell population and hybridized to GeneChip with 28,700 rat genes. Using the criterion of fold change > 4 in the expression level, we identified 83 genes that were up-regulated and 89 genes that were down-regulated in oligodendrocytes, and 92 genes that were up-regulated and 86 that were down-regulated in type II astrocytes compared with OPCs.
