| Research Abstract |
Osteoclastic bone resorption plays an important role on cancer-induced bone diseases like bone metastases or cancer bone invasion. We have been previously demonstrated that the interaction between angiogenesis and osteoclastic bone resorption. In the present study, we examined the Angiogenin (ANG) is and has been shown to play a role in both tumor angiogenesis and cancer cell proliferation during cancer development. Osteolytic bone invasion in nude mice model was suppressed by ANG RNAi transfection. Moreover, ANG stimulated osteoclast formation and activity in bone marrow culture system. These results suggest that ANG could be a molecular target for cancer-induced osteolysis.
