Abstract

We investigated here whether adiponectin can exhibit an inhibitory effect on tumor necrosis factor-alpha (TNF-α)- and receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis by using RAW264 cell D clone with a high efficiency to form osteoclasts. Globular adiponectin (gAd) strongly inhibited TNF-α/RANKL-induced differentiation of osteoclasts by interfering with TNF receptor-associated factor 6 production and calcium signaling; consequently, the induction of nuclear factor of activated T cells c1 (NFATc1) was strongly inhibited. Moreover, we observed that inhibition of AMP-activated protein kinase abrogated gAd inhibition for TNF-α/RANKL-induced NFATc1 expression. Our data suggest that adiponectin acts as a potent regulator of bone resorption observed in diseases associated with cytokine activation.
