摘要: 目的

初步探究miR-628-3p对胃癌细胞系HGC-27增殖和迁移能力的影响。

方法

qRT-PCR检测人正常胃黏膜细胞GES-1及HGC-27细胞miR-628-3p的表达水平。转染miR-628-3p模拟物后MTT法检测HGC-27细胞增殖,Transwell小室实验检测HGC-27细胞迁移能力,Western blot检测cyclinD1蛋白表达水平。

结果

与正常胃黏膜细胞相比,HGC-27细胞miR-628-3p表达显著降低(P < 0.01);与转染阴性对照组细胞相比,转染miR-628-3p模拟物组细胞活力显著降低(P < 0.01),转染miR-628-3p模拟物的HGC-27细胞穿过小室聚碳酸酯膜的细胞数目明显减少(P < 0.01),细胞增殖蛋白cyclinD1表达显著下调(P < 0.01)。

结论

miR-628-3p能够降低cyclinD1表达,抑制HGC-27细胞增殖和迁移。

Abstract: Objective

To preliminarily explore the effect of miR-628-3p on the proliferation and migration ability of gastric cancer cell line (HGC-27).

Methods

qRT-PCR was used to detect the expression level of miR-628-3p in human normal gastric mucosal cells (GES-1) and HGC-27 cells. The MTT method was used to detect the effect of overexpression of miR-628-3p on the proliferation of HGC-27 cells, and the Transwell chamber test was used to detect the effect on the migration ability of HGC-27 cells. Western blot was used to detect the expression level of cyclinD1 protein.

Results

Compared with normal gastric mucosal cells, the expression of miR-628-3p in HGC-27 cells was significantly reduced (P < 0.01); Compared with the negative control cells, the cell viability of the miR-628-3p mimic transfected group was significantly reduced (P < 0.01), the number of HGC-27 cells transfected with miR-628-3p mimics through the cell polycarbonate membrane was significantly reduced (P < 0.01), and the expression of cell proliferation protein cyclinD1 was significantly down-regulated (P < 0.01).

Conclusion

miR-628-3p can reduce the expression of cyclinD1 and inhibit the proliferation and migration of HGC-27 cells.
