Promotor hypermethylated genes: prospective diagnostic biomarkers in oral cancerogenesis

The advancements in epigenetics of oral squamous cell carcinoma (OSCC), are made in regard to DNA hypermethylation of MGMT, DAPK, ECAD (E-cadherin) and p16, as an important component of oral carcinogenesis and new potential biomarkers in molecular diagnostic strategies. The objective of the study was to evaluate the methylation status of the proposed genes and their possible role in the tumor genesis and diagnosis of OSCC. Materials and methods: From sixty surgically treated and molecularly analyzed patients, we obtained three groups of bioptical materials: tumor, normal contralateral and healthy tissues.
