摘要:

背景:研究证实葛根素对小鼠卵巢以及与睾丸切除所致骨质疏松具有很好的防治作用,但关于葛根素对成骨细胞分化的影响却少有报道。
目的:观察葛根素对成骨细胞碱性磷酸酶mRNA、骨涎蛋白mRNA、骨桥蛋白mRNA以及骨钙素mRNA表达的影响情况。
方法:体外培养小鼠成骨细胞MC3T3-E1细胞,随机分为3组。空白对照组仅更换培养基;葛根素组更换为含有葛根素1×10-6 mol/L培养基;雌二醇组更换为含有雌二醇1×10-7 mol/L培养基。RT-PCR法测定MC3T3-E1细胞碱性磷酸酶、骨涎蛋白、骨桥蛋白、骨钙素mRNA的表达
结果与结论:葛根素和雌二醇能够延长碱性磷酸酶表达时间,在第12天达到高峰;葛根素和雌二醇在第10天和第12天能够增加骨涎蛋白mRNA的表达。葛根素和雌二醇在第5天和第12天能够减少骨桥蛋白的表达;葛根素和雌二醇在第10天和第12天能够增强骨钙素表达。结果表明葛根素能够通过影响成骨细胞分化相关特征性蛋白mRNA表达,促进成骨细胞的分化,可能是葛根素抗骨质疏松的重要的细胞分子机制之一。

Abstract:

BACKGROUND: Experimental studies have showed that puerarin has an obvious protective effect on osteoporosis in ovariectomized and orchiectomized mice. But the influence of puerarin in the molecular level in the process of osteoblast differentiation is seldom reported.
OBJECTIVE: To observe the effect of puerarin on the mRNA expression of alkaline phosphatase, bone sialoprotein, osteopontin and osteocalcin in osteoblasts.
METHODS: The MC3T3-E1 cells from mice cultured in vitro were randomly divided into control group, puerarin group (10-6 mol/L puerarin) and estradiol group (10-7 mol/L estradiol) to observe the effects of puerarin on the differentiation of osteoblasts. mRNA expression of alkaline phosphatase, bone sialoprotein, osteopontin and osteocalcin in MC3T3-E1 cells was determined using RT-PCR method.
RESULTS AND CONCLUSION: Puerarin and estradiol both could prolong the expression of alkaline phosphatase that reached the peak at 12 days. Puerarin and estradiol strengthened the mRNA expression of bone sialoprotein at 10 and 12 days, reduced expression of osteopontin at 5 and 12 days, and increased expression of osteocalcin at 10 and 12 days. These results reveal that puerarin can induce the differentiation of  cultured osteoblasts by influencing osteoblast differentiation-related protein mRNA expressions, which may be one of the important molecular mechanisms of puerarin for prevention of osteoporosis.
