Atoh8 silencing-mediated promotion of Runx2 expression, osteoblast differentiation, and Rankl/Opg expression is inhibited by Runx2 knockdown in ST-2 cells. a–d ST-2 cells were transfected with the indicated siRNA, stimulated with or without 100 ng·mL−1 BMP-6 for 2 days, and subjected to RT-qPCR. Values were normalized to Hprt1 (n = 3). The data shown are the mean ± SD. n.s. not significant; *P < 0.05; **P < 0.01; ***P < 0.001
