Background: Acetyl-CoA-Carboxylase (ACC1), the rate-limiting enzyme of de novo lipogenesis, plays a critical role in beta cell growth and insulin secretion. In spite of plethora evidence for the role of ACC1 in insulin secretion and beta cells function both in vivo and in vitro, very little is known about how ACC1 activity is regulated in pancreatic beta cells. The aim of the current study was to screen for novel phospho-sites that may regulate ACC1 activity ...

Aims: Prolyl-4 hydroxylase domain protein 3 (PHD3) is an alpha ketoglutarate-dependent dioxygenase involved in the oxygen-dependent regulation of cell phenotype. While PHD3 has been reported to suppress insulin sensitivity in the liver, little is known about effects of the enzyme in insulin-secreting β-cells.Methods: βPHD3−/− mice were generated by crossing the Ins1Cre driver line with animals bearing a floxed Egln3</...
