Bone metastasis of breast cancer typically leads to osteolysis, which causes severe pathological bone fractures and hypercalcemia. Bone homeostasis is skillfully regulated through osteoblasts and osteoclasts. Bone loss with bone metastasis of breast cancer may be due to both activation of osteoclastic bone resorption and suppression of osteoblastic bone formation. This study was undertaken to determine whether the novel curcumin analogue UBS109 has preventive effects on bone loss induced by breast cancer cell bone metastasis. Nude mice were inoculated with breast cancer MDA-MB-231 bone metastatic cells (106 cells/mouse) into the head of the right and left tibia. One week after inoculation, the mice were treated with control (vehicle), oral administration (p.o.) of UBS109 (50 or 150 mg/kg body weight), or intraperitoneal administration (i.p.) of UBS109 (10 or 20 mg/kg body weight) once daily for 5 days per week for 7 weeks. After UBS109 administration for 7 weeks, hind limbs were assessed using an X-ray diagnosis system and hematoxylin and eosion staining to determine osteolytic destruction. Bone marrow cells obtained from the femurs and tibias were cultured to estimate osteoblastic mineralization and osteoclastogenesis ex vivo and in vitro. Remarkable bone loss was demonstrated in the tibias of mice inoculated with breast cancer MDA-MB-231 bone metastatic cells. This bone loss was prevented by p.o. administration of UBS109 (50 and 150 mg/kg body weight) and i.p. treatment of UBS109 (10 and 20 mg/kg) in vivo. Culture of bone marrow cells obtained from the bone tissues of mice with breast cancer cell bone metastasis showed suppressed osteoblastic mineralization and stimulated osteoclastogenesis ex vivo. These changes were not seen after culture of the bone marrow cells obtained from mice treated with UBS109. Moreover, UBS109 was found to stimulate osteoblastic mineralization and suppress lipopolysaccharide (LPS)-induced osteoclastogenesis in bone marrow cells obtained from normal nude mice in vitro. These findings suggest that the novel curcumin analogue UBS109 prevents breast cancer cell bone metastasis-induced bone loss by stimulating osteoblastic mineralization and suppressing osteoclastogenesis.
