| Research Abstract |
CCN2/CTGF which is a member of CCN2 family proteins binds to various cytokines and modulates the effects. We screened the binding proteins to CCN2/CTGF and found receptor activator of NF-kappaB(RANK). CCN2/CTGF also could bind to OPG which was a decoy receptor and inhibited the effect of RANK. In the RAW264. 7, preosteoclast, CCN2/CTGF augmented the stimulation of RANKL(RANK ligand) and attenuated the inhibitory effect of OPG on RANK/RANKL signaling. These data showed that CCN2/CTGF enhanced differentiation of osteoclast via two different pathways.
