To further examine the potential effects of PRDX2 in lung cancer cells, we analyzed the expression levels of PRDX2 in human normal bronchial epithelial cell line (BEAS-2B) and commonly used NSCLC cell lines (NCI-H460, NCI-H1650, NCI-H1299, and A549). This evidence concerns the gene PRDX2 and non-small cell lung carcinoma.
