Abstract:Background: The experimental evidence has demonstrated that active DNA demethylation process, which involves TET proteins, can affect DNA methylation pattern. TET dependent demethylation residues in DNA hypomethylation by oxidation 5-methylcytosine (5-mC) to 5-hydroxymethylcytosine (5-hmC) and its derivatives. TETs’ activity may be upregulated by ascorbate. Given that aberrant DNA methylation of crucial genes implicated in breast carcinogenesis may be involved in tumor progression, we wanted to determine wheth… Show more
