Fig. 1From: Aldehyde dehydrogenase 2 alleviates monosodium iodoacetate-induced oxidative stress, inflammation and apoptosis in chondrocytes via inhibiting aquaporin 4 expressionHigh expression of ALDH2 showed lower oxidative stress in knee joint effusion of patients with KOA. A ALDH2 expression was examined using western blot analysis. B–D Levels of MDA, SOD and ALDH were evaluated with commercial kits. **P < 0.01, ***P < 0.001Back to article page
