SIRT1 Deacetylates FOXA2 and Is Critical for Pdx1 Transcription and β-Cell Formation

Abstract excerpt

Pancreas duodenum homeobox 1 (PDX1) is essential for pancreas development and β-cell formation; however more studies are needed to clearly illustrate the precise mechanism regarding spatiotemporal regulation of Pdx1 expression during β-cell formation and development. Here, we demonstrate that SIRT1, FOXA2 and a number of proteins form a protein complex on the promoter of the Pdx1 gene. SIRT1 and PDX1 are...
