Fig. 3From: Impaired autophagy contributes to the aggravated deterioration of osteoarthritis articular cartilage by peroxisome proliferator-activated receptor α deficiency, associated with decreased ERK and Akt activationExpression of autophagy biomarkers in cartilage of PPARα-KO mouse model of experimental OA. Sections in different treated groups were examined using immunohistochemistry assay. A Representative image from mice of different treated groups expressing P62 (original magnification × 40). Graph shows the percentage of positive chondrocytes expressing P62. Data are mean ± SD of 500 cells per group (*p < 0.05); B representative images from mice of different treated groups expressing LC3B (original magnification × 40). Graph shows the percentage of positive chondrocytes expressing P62. Data are mean ± SD of 500 cells per group(*p < 0.05)Back to article page
