ALDH2 methylation analysis in lung adenocarcinoma. Promoter methylation levels of ALDH2 assessed using the UALCAN platform on TCGA samples; the beta value indicates the level of DNA methylation ranging from 0 (unmethylated) to 1 (fully methylated). Different beta value cutoffs have been considered to indicate hyper‐methylation [beta value: 0.70–0.50] or hypo‐methylation [Beta value: 0.30–0.25].
