Abstract：Objective To explore the effects of Bcl-2 and BaK gene silencing on cell apoptosis ,osteogen-esis activity and free Ca2+concentration of MG-63 cell lines. Methods The siRNA sequences targeted Bcl-2 and BaK respectively were designed;Bcl-2 and BaK silencing adenovirus vector scramble RNA vector and empty vec-tor were constructed to transfect MG-63 cell lines. MTT method was used to examine cell viability;ALP and flow cytometry were conducted to observe osteogenesis activity and free Ca2+concentration. Results Bcl-2 gene silenc-ing decreased cell viability,reduced osteogenesis activity and increased free Ca2+ concentration when compared with controls but BaK gene silencing had the opposite effects. The effect of Bcl-2+BaK gene silencing on cell was similar to the empty control. Conclusions Cell apoptosis,osteogenesis activity and free Ca2+concentration of MG-63 change following Bcl-2 and BaK gene silencing,implicating their roles in osteoporosis.
