| Summary | Nobiletin, a polymethoxy flavonoid, prevents cancer and inflammation, but the roles of nobiletin in bone are unclear. We examined the effects of nobiletin on bone resorption in vitro and on bone mass in ovariectomized (OVX) mice in vivo. In vitro, nobiletin suppressed osteoclast formation and bone resorption induced by interleukin (IL)-1. Nobiletin suppressed the expression of cyclooxygenase-2, NFκB-dependent transcription, and prostaglandin E (PGE) production induced by IL-1 in osteoblasts. OVX mice showed severe bone loss in the femur by increased bone resorption due to estrogen deficiency, and nobiletin significantly restored the bone mass. Nobiletin could be beneficial to bone health in postmenopausal women. |
