Effect of CR on the activation of NFATc1 and c-Fos by RANKL. a NFATc1 and b c-Fos protein expressions were determined by western blot. Expressions of c NFATc1 and d c-Fos were normalized to actin. 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
