Application
5-Methylcytosine hydrochloride has been used as standard in high performance liquid chromatography (HPLC) for the estimation of global methylation rates. It has also been used in high-resolution mass spectroscopic analysis.
5-Methylcytosine is used in studies of DNA methylation processes (epigenetics).
Biochem/physiol Actions
5-Methylcytosine mediates gene expression, genomic imprinting and inhibition of transposable elements. It is closely associated with translational fidelity and tRNA recognition.

Previous studies have revealed that mouse primordial germ cells (PGCs) undergo genome-wide DNA methylation reprogramming to reset the epigenome for totipotency. However, the precise 5-methylcytosine (5mC) dynamics and its relationship with the generation of 5-hydroxymethylcytosine (5hmC) are not clear. Here
