雌激素受体基因ERβ与小鼠成骨细胞的增殖和分化
Estrogen receptor beta inhibits the proliferation and differentiation of osteoblasts in mice
摘要
Abstract
BACKGROUND: Estrogen receptors (ERs) are expressed in cell components related to bone formation and resorption.OBJECTIVE: To investigate the regulatory effects of Er? on osteoblast proliferation and differentiation.METHODS: The mouse osteoblastic cell lines MC3T3-E1 were divided into 3 groups: experimental group (transfected ER?RNAi vector), negative control (transfected ERL RNAi vector), and blank control (no transfection). Three groups of cells were cultured under the same conditions. In each group, cell growth curve was drawn using MTT; and the cell cycle was analyzed by flow cytometry.RESULTS AND CONCLUSION: The cell proliferation in the experimental group was more significantly enhanced than in the negative control group or blank control group. The percentage of cells at G1-phase in the experimental group was significantly less than the other groups, while the percentage of cells at S-phase and G2-phase was significantly higher than the other groups (P < 0.05). According to test results of the ER? silence, we can infer that the ER? may inhibit the proliferation and differentiation of osteoblasts.关键词
