Fig. 5From: CHMP5 attenuates osteoarthritis via inhibiting chondrocyte apoptosis and extracellular matrix degradation: involvement of NF-κB pathwayCHMP5 constricted ECM degradation induced by IL-1β in the chondrocytes. (A, B) Western blot showed the levels of collagen II, aggrecan, SOX9, MMP13, MMP3 and ADAMTS5 in the chondrocytes. (C, D) IF staining of collagen II exhibited the protective effect of CHMP5 on ECM in the chondrocytes. Bar: 50 μmBack to article page
