The Preventive Effect of Biochanin A on Bone Loss in Ovariectomized Rats: Involvement in Regulation of Growth and Activity of Osteoblasts and Osteoclasts

Figure 1

Effects of BCA and E2 on osteoblast and osteoclast marker gene expression. mRNA expression in the distal femur was determined by RT-PCR for (a) osterix, (b) collagen type I, (c) ALP, (d) osteocalcin, or (e) TRAP. Expression was normalized to that of GAPDH and expressed as a percentage of that in the sham group. The bars represent mean SD for ten samples. * compared with the sham group; # compared with the OVX C group; compared with the E2 group. ALP: alkaline phosphatase; TRAP: tartrate-resistant acid phosphatase; C: control; BCA: biochanin A; E2: 17β-estradiol; OVX: ovariectomized.
