Liraglutide activates the PKA/CREB pathway in cartilage tissues of the knee OA rat model. Representative Western blots and quantification data of PKA, p-PKA, CREB and p-CREB in the “OA”, “OA + saline” and “OA + liraglutide” groups (n = 5 per group). * Indicates P < 0.05 compared with the “OA + saline” group
