Prospective study of predictors of beta-cell survival in type I diabetes.

abstract：:GLUT2 glucose transporter mRNA has been shown to be underexpressed in pancreatic islets of numerous animal models of non-insulin-dependent diabetes mellitus (NIDDM). It has been proposed that this molecular defect contributes to the pathogenesis of diabetes, although information concerning the expression of GLUT2 in h...
