Overexpression of PRDX2 promotes proliferation, migration, and invasion in NCI-H1299 cells. (a) NCI-H1299 cells were transfected with PRDX2-overexpressed or controlled plasmids, and the mRNA levels of PRDX2 were performed by qRT-PCR assay. (b) The protein levels of PRDX2 were performed by western blot assay. (c) Cell viability was performed using CCK8 assay. (d) Migration assay was performed using Transwell assay without Matrigel gel, and invasion assay was performed using Transwell assay with Matrigel gel. ∗P < 0.05, ∗∗P < 0.01; ∗∗∗P < 0.001.
