We proposed that besides TET family dioxygenase oxidizing 5mC to 5hmC, there is a non-enzyme pathway which is due to hydroxyl radica l(OH) or OH-like species also involvement in demethylation of 5mC forming 5hmC. This pathway includes classical fenton reagents such as H2O2 and Fe2+, and more importa...

DNA demethylation occurs in multiple cellular processes but its regulation is poorly understood. Here we report that a vital nutrient factor ascorbic acid (AA), or vitamin C (Vc), induces DNA demethylation in mammalian cells. The levels of active 5mC oxidation products, 5-formylcytosine and 5-carbox...
