摘要
5-Formylcytosine (5fC), produced by TET-mediated oxidation of 5-methylcytosine, is considered an intermediate in active DNA demethylation. Labeling studies and LC/MS analysis across mouse developmental stages reveals that 5fC modifications are more persistent in the genome and may have other functional roles.
