Fig. 2From: Ozone induces autophagy by activating PPARγ/mTOR in rat chondrocytes treated with IL-1βO3 treatment improved the cell viability at 30 μg/mL concentration. Chondrocytes were treated with IL-1β (10 ng/mL) for 24 h, then were dealt with different concentration of O3 for 30 min.*P < 0.05, **P < 0.01 versus Control group; #P < 0.05, ##P < 0.01 versus IL-1β groupBack to article page
