At the crossroad between metabolism and epigenetics: acetyl- CoA impacts cell plasticity in health

and disease

(Host: S. Zacchigna)

Emerging evidence show that metabolites’ concentration impacts the epigenome: many metabolites are substrates of, or cofactors for several chromatin remodeling enzymes. For example, the central Krebs’ cycle metabolite acetyl-CoA is also the donor substrate for acetylation reactions and its availability dictates global levels of histone acetylation. My work shows that acetyl-CoA availability fluctuates in mammalian cells and organs, in response to diet, nutrient availability, oncogenic signaling among other inputs. This ultimately influences cell fate decisions and has consequences for tumorigenesis.
