The role of noggin in regulation of high glucose-induced apoptosis and insulin secretion in INS-1 rat beta cells
Objective(s):The purpose of this study was to investigate the effects of Noggin on high glucose-induced apoptosis and insulin secretion in pancreatic beta cells. Materials and Methods: Different concentrations of glucose were used to examine their effects on INS-1 rat beta cells in vitro. When specific siRNA targeting Noggin and recombinant Noggin were added, apoptosis and insulin secretion wer...
متن کاملGeniposide Regulates Glucose-Stimulated Insulin Secretion Possibly through Controlling Glucose Metabolism in INS-1 Cells
Glucose-stimulated insulin secretion (GSIS) is essential to the control of metabolic fuel homeostasis. The impairment of GSIS is a key element of β-cell failure and one of causes of type 2 diabetes mellitus (T2DM). Although the KATP channel-dependent mechanism of GSIS has been broadly accepted for several decades, it does not fully describe the effects of glucose on insulin secretion. Emerging ...
متن کاملmTORC1 and mTORC2 regulate skin morphogenesis and epidermal barrier formation
Mammalian target of rapamycin (mTOR), a regulator of growth in many tissues, mediates its activity through two multiprotein complexes, mTORC1 or mTORC2. The role of mTOR signalling in skin morphogenesis and epidermal development is unknown. Here we identify mTOR as an essential regulator in skin morphogenesis by epidermis-specific deletion of Mtor in mice (mTOREKO). mTOREKO mutants are viable, ...
متن کاملInsulin Stimulates Adipogenesis through the Akt-TSC2-mTORC1 Pathway
BACKGROUND The signaling pathways imposing hormonal control over adipocyte differentiation are poorly understood. While insulin and Akt signaling have been found previously to be essential for adipogenesis, the relative importance of their many downstream branches have not been defined. One direct substrate that is inhibited by Akt-mediated phosphorylation is the tuberous sclerosis complex 2 (T...
متن کاملmTORC1 and mTORC2 differentially regulate homeostasis of neoplastic and non-neoplastic human mast cells.
Increased mast cell burden is observed in the inflamed tissues and affected organs and tissues of patients with mast cell proliferative disorders. However, normal mast cells participate in host defense, so approaches to preferentially target clonally expanding mast cells are needed. We found that mammalian target of rapamycin complex 1 (mTORC1) and 2 (mTORC2) are up-regulated in neoplastic and ...
