Effect of CR on the mRNA expression of osteoclastogenesis marker genes by RANKL. a The mRNA expressions were detected by RT-PCR. b osteoclastogenesis genes were normalized to GAPDH. Columns and error bars represent the mean ± S. E of three independent experiments. ##p < 0.01, #p < 0.05 compared with normal and **p < 0.01, *p < 0.05 compared with the control
