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. The gene discussed is DLC1; the disease is neoplasm.
