NQO1 and lung adenocarcinoma: Top 25 differentially methylated loci in promoters and negatively correlated with expression in 16 lung adenocarcinomas tissues using a methylation-sensitive restriction enzyme- based HELP microarray assay were found in Nandita Mullapudi’s study [19], NQO1 was appeared with hypomethylation and upregulated expression in Nandita Mullapudi’s [21] and this study.
