英文摘要
We have analyzed whether RGS-2 overexpression in osteoblasts will suppress Gq signal which is known to inhibit osteoblast differentiation leading enhancement of PTH osteoanabolic effect. RGS-2 suppressed Gq singnal and inhibited osteoblast differentiation. We have also screened small compounds that would suppress Gq signal, like RGS-2, in osteoblasts using our small compound library consisted of 20000 compounds. However, we could not find the small compounds that suppress both Gq signal and enhance PTH effect on osteoblast differentiation.
