摘要:

目的 分析GATA结合蛋白3(GATA3)介导微小RNA-21(miR-21)/人类第10号染色体缺失的磷酸酶及张力蛋白同源物(PTEN)轴对子宫内膜癌细胞增殖、侵袭的影响。 方法 取HEC-1-A细胞,进行转染分组,分为对照组、GATA3空载质粒组、GATA3过表达质粒组、GATA3 siRNA阴性对照组、GATA3 siRNA组。检测各组细胞中GATA3、miR-21、PTEN表达量、增殖情况、凋亡率、迁移、侵袭。 结果 与hEEC组相比,HEC-1-A组、HEC-1-B组、Ishikawa组细胞中GATA3、miR-21表达水平升高,PTEN表达水平降低(P < 0.05)。与GATA3空载质粒组相比,GATA3过表达质粒组GATA3、miR-21 mRNA表达量、增殖率、迁移距离、侵袭细胞数、Vimentin水平升高,PTEN mRNA表达量、凋亡率、Caspase-9、Bax、E-cadherin水平降低(P < 0.05);与GATA3 siRNA阴性对照组相比,GATA3、miR-21 mRNA表达量、增殖率、迁移距离、侵袭细胞数、Vimentin水平降低,PTEN mRNA表达量、凋亡率、Caspase-9、Bax、E-cadherin水平升高(P < 0.05)。 结论 下调GATA3表达,可对miR-21/PTEN轴进行调节,使HEC-1-A细胞的增殖减慢,促进HEC-1-A细胞的凋亡。

Abstract:

Objective To analyze the effects of GATA binding protein 3 (GATA3) mediated mini RNA-21 (miR-21)/phosphatase and tensin homologue (PTEN) axis missing from human chromosome Chromosome 10 on the proliferation and invasion of endometrial cancer cells. Methods HEC-1-A cells were transfected and divided into control group, GATA3 empty plasmid group, GATA3 overexpression plasmid group, GATA3 siRNA negative control group, and GATA3 siRNA group. Detect the expression levels of GATA3, miR-21, PTEN, proliferation, apoptosis rate, migration, and invasion in each group of cells. Results Compared with the hEEC group, the expression levels of GATA3 and miR-21 in cells of the HEC-1-A group, HEC-1-B group, and Ishikawa group increased, while the expression levels of PTEN decreased (P < 0.05). Compared with the GATA3 empty plasmid group, the GATA3 overexpression plasmid group showed an increase in GATA3, miR-21 mRNA expression, proliferation rate, migration distance, number of invading cells, and Vimentin levels, while the PTEN mRNA expression, apoptosis rate, Caspase-9, Bax, and E-cadherin levels decreased (P < 0.05); Compared with the GATA3 siRNA negative control group, the GATA3, miR-21 mRNA expression, proliferation rate, migration distance, number of invading cells, and Vimentin level decreased, while the PTEN mRNA expression, apoptosis rate, Caspase-9, Bax, and E-cadherin levels increased (P < 0.05). Conclusion Downregulation of GATA3 expression can regulate the miR-21/PTEN axis, slow down the proliferation of HEC-1-A cells, and promote apoptosis of HEC-1-A cells.
