摘要: 目的:探讨miR-93-5p在骨碎补总黄酮(TFRD)介导的兔骨髓间充质干细胞(rBMSCs)成骨分化中的作用。方法:采用成骨培养液对rBMSCs进行成骨诱导分化,通过茜素红S和油红O染色分别检测rBMSCs的成骨和成脂分化。运用荧光定量PCR(qPCR)检测miR-93-5p的表达,Western免疫印迹检测FZD6、ALP、Runx2和WNT通路相关蛋白(Dishevelled和β-catenin)的蛋白表达水平。双荧光素酶报告基因分析法检验miR-93-5p和FZD6的结合。采用SPSS 22.0软件包对数据进行统计学分析。结果:与对照组相比,TFRD促进rBMSCs的成骨分化,抑制miR-93-5p的表达,促进FZD6和成骨相关基因ALP和Runx2的表达。双荧光素酶报告基因分析表明,FZD6是miR-93-5p的下游靶基因。过表达miR-93-5p抑制rBMSCs的成骨分化和FZD6、ALP和Runx2的蛋白表达,而过表达FZD6逆转miR-93-5p的抑制作用。使用WNT通路抑制剂(KYA1797K)处理rBMSCs,可逆转TFRD对成骨分化的促进作用,导致成骨细胞分化减少,ALP、Runx2和WNT通路相关蛋白(Dishevelled和β-catenin)表达下调。结论:TFRD通过下调miR-93-5p,促进FZD6的表达,激活WNT信号通路,促进rBMSCs成骨分化,从而有助于口腔种植体骨结合。

Abstract: PURPOSE: To investigate the role of miR-93-5p in osteogenic differentiation of rabbit bone marrow mesenchymal stem cells (rBMSCs) mediated by total flavonoids of rhizoma drynariae(TFRD). METHODS: The osteogenic differentiation of rBMSCs was induced by osteogenic medium. The osteogenic and adipogenic differentiation of rBMSCs were detected by Alizarin red S and oil red O staining, respectively. The expression of miR-93-5p was detected by fluorescence quantitative PCR (qPCR), and the expression level of FZD6, ALP, Runx2 and WNT pathway related proteins (Dishevelled and β-catenin) was detected by Western blotting. The binding of miR-93-5p and FZD6 was tested by double-luciferase reporter gene analysis. The data were analyzed with SPSS 22.0 software package. RESULTS: Compared with the control group, TFRD promoted the osteogenic differentiation of rBMSCs, inhibited the expression of miR-93-5p, and promoted the expression of FZD6 and osteogenic related genes ALP and Runx2. Double-luciferase reporter gene analysis showed that FZD6 was the downstream target gene of miR-93-5p. Overexpression of miR-93-5p inhibited the osteogenic differentiation of rBMSCs and the protein expression of FZD6, ALP and Runx2, while overexpression of FZD6 reversed the inhibitory effect of miR-93-5p. Treatment of rBMSCs with WNT pathway inhibition (KYA1797K) could reverse the promoting effect of TFRD on osteogenic differentiation, resulting in reduced osteoblast differentiation and downregulation of ALP, Runx2 and WNT pathway related proteins (Dishevelled and β-catenin). CONCLUSIONS: TFRD promote the osteogenic differentiation of rBMSCs by downregulating miR-93-5p and upregulating FZD6 to activate the WNT signaling pathway, which contributes to the osseointegration of dental implant.
