摘要:

文题释义: 

补骨脂素:属呋喃香豆素类化合物,为常用补肾中药补骨脂的主要生物活性成分,现代药理学研究显示补骨脂素具有抗骨质疏松、抗肿 瘤、抗菌和抗炎等作用。 

骨髓间充质干细胞:是骨髓中一类来源于中胚层的多能干细胞,具有分化为成骨细胞、脂肪细胞等多种不同间质细胞谱系的能力。 


背景:补骨脂素具有很强的抗骨质疏松活性,可能对化疗导致的骨质疏松具有恢复作用。 

目的:探讨补骨脂素对环磷酰胺抑制小鼠骨髓间充质干细胞成骨分化的恢复作用及机制。 

方法:分离培养C57BL/6小鼠骨髓间充质干细胞,以MTT法检测补骨脂素对骨髓间充质干细胞活力的影响,以成骨诱导结合碱性磷酸酶染 色确定补骨脂素对环磷酰胺抑制骨髓间充质干细胞成骨分化恢复作用的最佳剂量。采用RT-qPCR法检测补骨脂素干预不同时间点成骨分化 标志基因Runx2、ALP、Osteocalcin、骨保护素及Wnt/β-catenin 信号通路相关基因Wnt1、Wnt4、Wnt10b、β-catenin、c-MYC的mRNA表达; 采用Western blot 法检测补骨脂素干预不同时间点成骨特异性转录因子Runx2及Wnt/β-catenin 信号通路相关基因Active β-catenin、DKK1、 c-MYC、Cyclin D1的蛋白表达。 

结果与结论:①不同浓度补骨脂素对骨髓间充质干细胞活力没有显著影响;200 μmol/L补骨脂素干预后对环磷酰胺诱导骨髓间充质干 细胞成骨分化抑制的恢复作用最佳;②补骨脂素可以逆转环磷酰胺条件培养基导致的骨髓间充质干细胞成骨标志基因Runx2、ALP、Osteocalcin、骨保护素mRNA表达和Runx2蛋白表达的降低;③补骨脂素可以逆转环磷酰胺条件培养基导致的骨髓间充质干细胞Wnt/ β-catenin通路相关基因Wnt4、β-catenin、c-MYC mRNA表达和Active β-catenin、c-MYC、Cyclin D1蛋白表达的降低以及DKK1蛋白表达的升高;④结果表明,环磷酰胺能抑制小鼠骨髓间充质干细胞成骨分化,补骨脂素对其具有恢复作用,且200 μmol/L补骨脂素干预效果最佳, 而这种保护作用可能与补骨脂素激活Wnt4/β-catenin信号通路有关。

Abstract:

BACKGROUND: Psoralen has a strong anti-osteoporotic activity and may have a restorative effect on chemotherapy-induced osteoporosis. 

OBJECTIVE: To explore the restorative effect of psoralen on the osteogenic differentiation of bone marrow mesenchymal stem cells in mice inhibited by cyclophosphamide and its mechanism. 

METHODS: C57BL/6 mouse bone marrow mesenchymal stem cells were isolated and cultured. Effect of psoralen on viability of bone marrow mesenchymal stem cells was detected by MTT assay. Osteogenic induction combined with alkaline phosphatase staining was used to determine the optimal dose of psoralen to restore the osteogenic differentiation of bone marrow mesenchymal stem cells inhibited by cyclophosphamide. The mRNA expression levels of Runx2, alkaline phosphatase, Osteocalcin, osteoprotegerin, and Wnt/β-catenin signaling pathway-related genes Wnt1, Wnt4, Wnt10b, β-catenin, and c-MYC were measured by RT-qPCR at different time points under the intervention with psoralen. The protein expression of osteogenic specific transcription factor Runx2 and Wnt/β-catenin signaling pathway related genes Active β-catenin, DKK1, c-MYC, and Cyclin D1 was determined by western blot assay at different time points under the intervention with psoralen. 

RESULTS AND CONCLUSION: (1) There was no significant effect of different concentrations of psoralen on the viability of bone marrow mesenchymal stem cells. The best recovery of the inhibition of osteogenic differentiation of bone marrow mesenchymal stem cells caused by cyclophosphamide was under the intervention of psoralen at a concentration of 200 μmol/L. (2) Psoralen reversed the reduction in osteogenic differentiation marker genes Runx2, alkaline phosphatase, Osteocalcin and osteoprotegerin mRNA expression and Runx2 protein expression in bone marrow mesenchymal stem cells caused by cyclophosphamide conditioned medium. (3) Psoralen reversed the decrease in Wnt/β-catenin pathway-related genes Wnt4, β-catenin, c-MYC mRNA and Active β-catenin, c-MYC, and Cyclin D1 protein expression and the increase in DKK1 protein expression in bone marrow mesenchymal stem cells caused by cyclophosphamide conditioned medium. (4) The results showed that cyclophosphamide inhibited osteogenic differentiation of bone marrow mesenchymal stem cells in mice, and psoralen had a restorative effect on it. The best intervention effect was achieved at a concentration of 200 μmol/L psoralen, and this protective effect might be related to the activation of Wnt4/β-catenin signaling pathway by psoralen.

Key words: cyclophosphamide, bone marrow mesenchymal stem cell, osteogenic differentiation, psoralen, Wnt4, β-catenin
