In EBV-associated NPC, Hutajulu et al. [138] detected aberrant methylation of four tumor-suppressor genes (DAPK1, DLC1, CDH13, and CADM1) in DNA from nasopharyngeal brushing samples of cancer patients, high-risk subjects, and healthy EBV carriers, and also detected DNA methylation of CDH1, DAPK1, and p16 in the peripheral blood of NPC patients. This evidence concerns the gene DAPK1 and neoplasm.
