A novel glucose-responsive element in the human insulin gene functions uniquely in primary cultured islets

Abstract excerpt

Insulin gene transcription is limited to the beta cells within the mammalian pancreas and, like insulin secretion, is regulated by glucose. Our previous studies in primary cultured beta cells suggested the presence of a strong glucose-responsive enhancer element between base pairs -341 and -260 of the human insulin promoter, the same region in which a transcriptional repressor had been identified in beta-cell...
