Fig. 8From: IL-15 deficiency alleviates steroid-induced osteonecrosis of the femoral head by impact osteoclasts via RANKL-RANK-OPG systemIL-15 deficiency regulates the RANKL/RANK/OPG signaling pathway in mice with steroid-induced ONFH. a RANK, RANKL, and OPG levels in the femoral heads were detected at protein levels by western blot. b shows the ratio of RANK, RANKL, RUNK2, BMP7 and OPG/GAPDH. The data are expressed as means ± SD(n = 3). ** p < 0.01 versus the WT ON groupBack to article page
