title: Overexpression of glucose transporter modulates insulin biosynthesis in insulin producing cell line.
abstract: Glucose transporter (GT) has been suggested to be involved in the insulin biosynthesis. However, the functional relationship between GT and insulin biosynthesis is not well understood. In this report, we have generated rat pancreatic B cell lines (RINr) that stably overexpress a cDNA encoding the brain type GT. These cell lines showed 3- to 4-fold increase in insulin mRNA and protein. These results suggest that GT might have some relationship to the insulin biosynthesis in the pancreatic B cells.
