MicroRNA-146a Induced by Hypoxia Promotes Chondrocyte Autophagy through Bcl-2

Abstract

HIF-1α, miR-146a and Bcl-2 play crucial roles during hypoxia-induced autophagy, Hypoxia, HIF-1α and miR-146a promote chondrocytes autophagy via depressing Bcl-2. We conclude that miR-146a may serve as a novel therapeutic target for protecting cartilage from degeneration in OA.
