Global DNA 5‐Hydroxymethylcytosine and 5‐Formylcytosine Contents Are Decreased in the Early Stage of Hepatocellular Carcinoma
Jiao Liu, Jinhua Jiang, Jiezhen Mo, Dan Liu, Dan Cao, Hailin Wang, Yufei He, Hongyang Wang – 2 August 2018 – Methylation of the fifth position of cytosine (5mC) is an important epigenetic modification of DNA. It has been shown that the oxidized derivatives of 5mC, namely 5‐hydroxymethylcytosine (5hmC), 5‐formylcytosine (5fC), and 5‐carboxylcytosine (5caC), are in dynamic existence and have distinct regulatory functions.
