Effects of BCA and E2 on RANKL and OPG mRNA expression. The mRNA levels for RANKL (b) and OPG (c) in the distal femur were determined by RT-PCR. Expression was normalized to that of GAPDH and expressed as a percentage of that in the sham group. The bars represent the mean ± SD for ten samples. *P < 0.05 compared with the sham group; # P < 0.05 compared with the OVX C group; ∇ P < 0.05 compared with the E2 group. RANKL: receptor activator of nuclear factor-κB ligand; OPG: osteoprotegerin; C: control; BCA: biochanin A; E2: 17β-estradiol; OVX: ovariectomized.
