Abstract:

Vitamins A and C represent unrelated sets of small molecules that are essential to the human diet and have recently been shown to intensify erasure of epigenetic memory in naive embryonic stem cells. These effects are driven by complementary enhancement of the ten-eleven translocation (TET) demethylases - vitamin A stimulates TET expression, whereas vitamin C potentiates TET catalytic activity. Vitamin A and C cosupplementation synergistically enhances reprogramming of differentiated cells to the naive state, but overuse may exaggerate instability of imprinted genes. As such, optimizing their use in culture media will be important for regenerative medicine and mammalian transgenics. In addition, mechanistic perception of how these vitamins interact with the epigenome may be relevant for understanding cancer and improving patient treatment.
