Abstract excerpt
The development of esophageal squamous cell carcinoma (ESCC) has been linked to exposure to carcinogens such as nitrosamines that cause various alkyl DNA damages and O6-methylguanine-DNA methyltransferase (MGMT) is a primary defence against alkylation-induced mutagenesis and carcinogenesis. This study was to investigate the role of inactivation of MGMT by promoter hypermethylation and its relation to p53...
