1 In islet beta-cells, the high expression of pyruvate carboxylase and the functional importance of the downstream anaplerosis pathways result in a unique characteristic whereby high glucose and fatty acids both increase production of a key fatty acid metabolite, long chain acyl-CoA, for signaling and enzyme regulation in beta-cells.
