Here, we show that developmental dynamics of 5fC levels in mouse DNA differ from those of 5-hydroxymethylcytosine (5hmC), and using stable isotope labeling in vivo, we show that 5fC can be a stable DNA ...
On the other hand, we recently demonstrated that 5hmC is a predominantly stable modification in mammalian DNA, especially in the adult mouse brain where 5hmC is most abundant 6 . ...
Therefore, the lack of 5fC labeling in the adult brain means that this modified base must be stable in the genome as opposed to generally acting as a dynamic intermediate of active DNA demethylation. ...
