  We investigated the mRNA expression of V-ATPase CA II, NFAT2, and RANK as well as bone mineral density (BMD) in bilaterally ovariectomized (OVX) rats treated with pulsed electromagnetic fields (PEMF), to explore the mechanism by which PEMF alter bone at the molecular level in vivo. 24 Sprague–Dawley female rats were randomly divided into three different groups: SHAM, OVX, ovariectomy with PEMF stimulation (PEMF+OVX). The PEMF frequency was 3.8 mT, 8 Hz, for 40 min per day. Eight rats in each group were treated for 28 days. At the end of the intervention, the body weight and BMD were measured. The mRNA expression of V-ATPase, CA II, NFAT2 and RANK were analyzed by real-time fluorescent-nested quantitative polymerase chain reaction (RT-PCR). The V-ATPase, CAII, NFAT2 and RANK genes show strong expression in the OVX group as compared with the SHAM group (P<0.001, respectively). .. Read More»
