To pursue this question, we examined a data set consisting of matched transcriptome, proteome, and MHC class I peptidome data38 in which the authors originally examined the treatment effect of 5-aza-2’-deoxycytidine (decitabine, an inhibitor of DNA methyltransferase 1) on GBM cell lines. This evidence concerns the gene DNMT1 and glioblastoma.
