| Research Abstract |
Autophagy is an intracellular self-clearance mechanism. In this study, we hypothesized that autophagy is involved in pathogenesis and progression of osteoarthritis (OA). We conditionally disrupted Atg5, an essential gene for induction of autophagy,in cartilage of mice and analyzed. We also examined the effects of rapamycin, an activator of autophagy against development of OA. Progression of OA induced by destabilization of medial meniscus was accelerated in the cartilage-specific Atg5 knockout mice while progression of OA was delayed by the treatment of rapamycin. Our observation suggests that autophagy plays an important role in pathogenesis and progression of OA.
