タイトル Differentiation-induced insulin secretion from nonendocrine cells with engineered human proinsulin cDNA.
ジャーナル Biochem Biophys Res Commun
Abstract To investigate the effects of differentiation on insulin secretion from engineered nonendocrine cells, modified human proinsulin cDNA (INS/fur) was transfected to THP-1 monocyte and C2C12 myoblast cell lines. When THP-1 was differentiated into macrophages with phorbol ester, the insulin secretion rate was increased by 3.1-fold. This increase in insulin secretion is accompanied by a 17.6-fold increase in the processing efficiency of the modified human proinsulin and by a 3.5-fold increase in the abundance of furin mRNA. In addition, differentiation of C2C12 into myotubes, which can be induced by changing the serum, showed a 9.9-fold increase in insulin secretion and was accompanied by a 1.6-fold increase in the abundance of furin mRNA. The involvement of posttranslational processing and the exocytotic process in differentiation-induced insulin secretion could lead to the possibility of regulation of insulin secretion from genetically engineered cells.
