WebFeb 28, 2024 · Background: DNA methylation at the 5 position of cytosine (5mC) can be converted to 5-hydroxymethylcytosine (5hmC) by the ten-eleven translocation family. The loss of global levels of 5hmC has been regarded as a hallmark in various cancers. 5-hydroxymethylcytosine is distributed at protein-coding gene bodies and promoters; … WebMethylated cytosines and schematic setup.

WebThis pathway removes the methyl group from cytosine, which is involved in the oxidation of 5-methylcytosine to 5-hydroxymethylcytosine (5-hmC) by ten-eleven translocation (TET) proteins (Table 1.2). Then 5-hmC can be iteratively oxidized to generate 5-formylcytosine and 5-carboxylcytosine. 52 WebJul 7, 2024 · As one of the most important DNA epigenetic modifications, 5-methylcytosine (5-mC) plays crucial functional roles in diverse biological processes [1,2,3,4].DNA methylation is dynamically regulated by DNA methyltransferases and demethylases [5, 6].The active demethylation of 5-mC is involved in stepwise oxidation of 5-mC by ten …
