glucokinase could create a substrate cycle and therefore modulate β cell glycolytic flux and glucose-stimulated insulin secretion ( Newgard et al . 2002 ). Indeed, recent genetic data also suggest that variations in IGRP expression and/or activity are linked

(7-36) amide form, with a lesser amount of the bioactive GLP-1(7-37) form also detectable ( Kreymann et al. 1987 ). The biological activities of GLP-1 include stimulation of glucose-dependent insulin secretion and insulin biosynthesis, inhibition of glucagon

sequences with partial complementarity in the 3′-untranslated regions (3′-UTRs) of mRNAs, resulting in mRNA degradation ( Lai 2002 , Krol et al . 2010 ). A number of miRNAs have been shown to regulate insulin secretion. For example, miR-184 inhibits
