Research Abstract

Arctigenin, an anti-tumor compound, is a plant-derived natural molecule. We find that arctigenin inhibits osteoclast formation and function. In RANKL-induced osteoclastogenesis arctigenin markedly represses the transcriptional activity of NFATc1.Our results suggest that a novel mechanism of NFATc1 in its transcriptional regulation, that is different from a known inhibitory mechanism by which NFATc1 is retained in the cytosol.
