Description

Uncoupling protein 2 (UCP2) is a mitochondrial carrier protein that is expressed in pancreatic islets and has been shown to negatively regulate glucose-stimulated insulin secretion.1,2 High levels of UCP2 expression can disrupt pancreatic β cell function and downregulate insulin secretion thereby contributing to the development of type 2 diabetes.3 Genipin, a compound isolated from Gardenis jasminoides Ellis fruits, was originally identified as a protein cross-linking agent. Genipin is a cell-permeable inhibitor of UCP2 activity.4 Genipin, at 5 µM, increases glucose-stimulated insulin secretion in isolated pancreatic islets chronically exposed to high levels of glucose.5 Genipin also exhibits anti-inflammatory and anti-angiogenic properties by inducing apoptosis in FaO rat hepatoma cells and human hepatocarcinoma Hep3B cells.6
