Fig. 1From: Impaired autophagy contributes to the aggravated deterioration of osteoarthritis articular cartilage by peroxisome proliferator-activated receptor α deficiency, associated with decreased ERK and Akt activationAggravated cartilage damage in PPARα-KO mouse model of experimental OA by DMM. A Sections in different treated groups were examined using Safranin O-Fast green stain (original magnification × 20); B graph shows the change in articular cartilage thickness in medial femur condyle and tibial plateau. Data are mean ± SD of eight joints per group (*p < 0.05); C graphs show the histopathological assay performed by OARSI histopathology assessment system in medial femur condyle and tibial plateau. Data are mean ± SD of eight joints per group (*p < 0.05)Back to article page
