Aldehyde dehydrogenase 1a3 defines a subset of failing pancreatic β cells in diabetic mice

Abstract

Diabetes is associated with the de-differentiation of β-cells into a more progenitor-like cell type. Here, the authors identify Aldh3 as a marker of de-differentiating β-cell in animal models of diabetes, and show Aldh3+cells have impaired insulin secretion and mitochondrial dysfunction.
