CAMP gene methylation inhibited the proliferation of osteoarthritis articular cartilage cells and promoted their apoptosis. a The cell proliferation ability of Control, sh-CAMP-transfected HC-OA cells, and 5-μM AZA-treated HC-OA cells were detected by CCK-8. b The apoptotic rate of Control, sh-CAMP-transfected HC-OA cells and 5-μM AZA-treated HC-OA cells were detected by flow cytometry. ^*p < 0.05, ^**p < 0.01, ^***p < 0.001, compared with Control
