Breathing-in epigenetic change with vitamin C.
Ontology highlight
ABSTRACT: Vitamin C is an antioxidant that maintains the activity of iron and α-ketoglutarate-dependent dioxygenases. Despite these enzymes being implicated in a wide range of biological pathways, vitamin C is rarely included in common cell culture media. Recent studies show that reprogramming of pluripotent stem cells is enhanced when vitamin C is present, thereby illustrating previous limitations in reprogramming cultures. Here, we summarize understanding of dioxygenase function in reprogramming and epigenetic regulation. The available data suggest a link between dioxygenase function and stem cell differentiation, which is exposed to environmental influence and is relevant for human disease.
