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.
