Objective To identify causal effects and potential mechanisms of oxidative stress (OS) genes in lung cancer. Methods OS-related genes were extracted from the GeneCards database. Integration analysis of genome-wide association study (GWAS) data for lung cancer with gene expression and DNA methylation quantitative trait loci (eQTL and mQTL) in blood was performed using the summary data-based Mendelian randomization (SMR) approach to determine the causal relationship between OS genes and lung cancer risk. Colocalization analysis of OS gene QTLs and lung cancer risk loci was performed to gain insight into the potential regulatory mechanisms of lung cancer risk. Results A potential causal relationship between OS-related genes and lung cancer was identified by SMR analysis. AGER expression level was found to be associated with lung cancer risk [OR=1.944, 95%CI (1.431, 2.640), P<0.001], and ATF6B expression level was associated with lung cancer risk [OR=1.508, 95%CI (1.287, 1.767), P<0.001]. Meanwhile, ATF6B methylation level was associated with lung cancer risk. Conclusion OS-related genes are associated with lung cancer, which may be a potential site of action for anti-cancer drugs.
