BP terms enriched significantly in lung cancers included cellular response to oxidative stress, process utilizing autophagic mechanism, cell death in response to oxidative stress and positive regulation of epithelial cell apoptotic process; whereas MF terms enriched significantly in lung cancers included antioxidant activity, MAP kinase activity, oxidoreductase activity, and protein phosphorylated amino acid binding (Figures 5A, B). Here, TXNRD1 is linked to lung carcinoma.
