Transcription factors involved in glucose-stimulated insulin secretion of pancreatic beta cells

GSIS, the most important function of pancreatic beta cell, is essential for maintaining the glucose homeostasis. Transcription factors are known to control different biological processes Such as differentiation, proliferation and apoptosis. In pancreas, some transcription factors are involved in regulating the function of beta cells. In this review, the role of these transcription factors including Pdx-1, FoxO1, SREBP-1c, and MafA in GSIS is highlighted. The related molecular mechanisms are analyzed as well. Furthermore, the association between the role of transcription factors in GSIS and the development of T2DM is discussed. (C) 2009 Published by Elsevier Inc.
