Tanshinone IIA attenuates osteoclastogenesis in ovariectomized mice by inactivating NF-kB and Akt signaling pathways.

ABSTRACT: Osteoporosis is a common disease associated with age and menopausal status. Postmenopausal osteoporosis is the most common type of primary osteoporosis and is accompanied by increased risk of osteoporotic fracture. Natural and herbal compounds have long been used to prevent and treat many human diseases. Here, we demonstrated that tanshinone IIA prevented ovariectomy-induced bone loss in an in vivo mouse model that closely mimics osteoporosis. In addition, we found that tanshinone IIA inhibited the receptor activator of nuclear factor NF-κB ligand (RANKL)-induced osteoclast differentiation and osteoclastogenesis in vitro. Tanshinone IIA treatment also abrogated RANKL-induced activation of the NF-κB pathway, PI3-kinase/Akt signaling, and the mitogen-activated protein kinase (M
