ABSTRACT
AIM:To investigate the effects of peroxiredoxin 4 ( Prdx4) protein expression levels on the migra-tion and invasion of human cervical cancer HeLa cells.METHODS:The plasmid pcDNA3.0-HA-Prdx4 was transfected into HeLa cells.The HeLa cells were infected with LV-Prdx4 RNAi vector to establish stable Prdx4 shRNA HeLa cells. The change in the expression of Prdx4 protein was validated by Western blotting.The wound-healing assay, and Transwell migration and invasion assays were performed to detect the migration and invasion of HeLa cells, respectively.RESULTS:The expression of Prdx4 protein was up-regulated in the HeLa cells after transfection with pcDNA3.0-HA-Prdx4 plasmid ( P<0.05), whereas it was down-regulated in the Prdx4 shRNA HeLa cells (P<0.05).The abilities of migration and inva-sion were significantly increased in Prdx4-overexpressing HeLa cells compared with non-transfected and mock plasmid trans-fected control groups ( P<0.01) .When Prdx4 was knocked down by shRNA, the migration and invasion of the HeLa cells were remarkably repressed compared with blank control group and negative control group ( P<0.01 ) .CONCLUSION:The up-regulation of Prdx4 expression facilitates the migration and invasion of HeLa cells, and the down-regulation of Prdx4 expression inhibits the migration and invasion of HeLa cells, indicating that Prdx4 may be a potential molecular target for cervical cancer therapy.
