摘要:
目的:探讨补骨脂异黄酮通过调控miR-497-5p抑制瘢痕疙瘩成纤维细胞增殖和迁移的机制研究。方法:体外培养瘢痕 疙瘩成纤维细胞,使用浓度为0、9、18、36μg/ml补骨脂异黄酮处理细胞,记为Con组、低剂量组、中剂量组、高剂量组; 按照脂质体法miR-NC、miR-497-5p转染细胞,记为miR-NC组、miR-497-5p组;按照脂质体法anti-miR-NC、anti-miR-497-5p 转染细胞后,使用36μg/ml补骨脂异黄酮处理细胞,记为高剂量组+anti-miR-NC组、高剂量组+anti-miR-497-5p组。CCK8、 克隆实验检测细胞增殖;伤口愈合实验检测细胞迁移;Western blot实验检测Cyclin D1、MMP2、MMP9蛋白表达水平;qRTPCR实验检测miR-497-5p表达水平。结果:补骨脂异黄酮呈剂量关系降低瘢痕疙瘩成纤维细胞活性、迁移率(P<0.05),减 少克隆细胞数(P<0.05),降低Cyclin D1、MMP2、MMP9蛋白表达水平(P<0.05),增加miR-497-5p表达水平。与miR-NC 组相比,miR-497-5p组细胞活性、迁移率降低(P<0.05),克隆细胞数减少(P<0.05),Cyclin D1、MMP2、MMP9蛋白表 达水平降低(P<0.05)。抑制miR-497-5p可以逆转补骨脂异黄酮对瘢痕疙瘩成纤维细胞增殖、迁移的影响。结论:补骨脂 异黄酮可能通过上调miR-497-5p抑制瘢痕疙瘩成纤维细胞增殖和迁移。 [
Abstract:
Objective To investigate the mechanism of psoralen isofl avones inhibiting the proliferation and migration of keloid fibroblasts by regulating miR-497-5p. Methods Keloid fibroblasts were cultured in vitro and treated with 0, 9, 18, 36 μg/ ml psoralen isofl avones, which were classifi ed as Con group, low dose group, medium dose group and high dose group. The cells were transfected with miR-NC and miR-497-5p by liposome method, and were denoted as miR-NC group and miR-497- 5p group. After transfection with anti-miR-NC and anti-miR-497-5p by liposome method, the cells were treated with 36 μg/ ml psoralen isofl avones, which were denoted as high-dose group +anti-miR-NC group and high-dose group +anti-miR-497-5p group. Cell proliferation was detected by CCK8 and cloning assay. Cell migration was detected by wound healing test. The expression levels of Cyclin D1, MMP2 and MMP9 were detected by Western blot assay. The expression level of miR497-5p was detected by qRT-PCR. Results Psoralen isofl avones decreased the cell viability and migration rate of keloid fi broblasts (P <0.05), decreased the number of cloned cells (P<0.05), and decreased the protein expression levels of Cyclin D1, MMP2, and MMP9 (P<0.05), increase the expression level of miR-497-5p. Compared with the miR-NC group, the cell viability and migration rate of the miR-497-5p group were reduced (P<0.05), the number of cloned cells was reduced (P<0.05), and the protein expression levels of Cyclin D1, MMP2, and MMP9 were reduced (P<0.05). Inhibition of miR-497-5p can reverse the eff ect of psoralen isofl avones on the proliferation and migration of keloid fi broblasts. Conclusion Psoralen isofl avones may inhibit the proliferation and migration of keloid fi broblasts by increasing miR-497-5p.
