Introduction: Enteroendocrine cells (EECs) are hormone-secreting cells within the intestinal epithelium that play an important role in regulating food absorption, insulin secretion and appetite. To understand the molecular mechanism governing the function of EECs, it is important to investigate cell-type-specific gene expression. The aim of this study was to identify the transcriptome of human EEC populations from organoid culture.Methods: To label the f...

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</...
