DNA methylation and the association between genetic and epigenetic changes: relation to carcinogenesis.

Abstract excerpt

This paper examines the relationship between DNA mutagenic lesions, DNA methylation and the involvement of these changes in the process of carcinogenesis. Many types of DNA damage (oxidative lesions, alkylation of bases, abasic sites, photodimers, etc.) interfere with the ability of mammalian cell DNA to be methylated at CpG dinucleotides by DNA-methyltransferases (DNA-MTases). This can result in altered patterns...
