A compelling body of evidence suggests an intimate relationship between metabolic state and chromatin regulation. This link is manifested in key metabolites that participate in biochemical pathways as intermediates, and function as cofactors to regulate chromatin modifying enzymes. Of particular interest is the metabolite acetyl-CoA, given its central role as an intermediate of cellular energy metabolism and key determinant of all histone acetylation. How nuclear acetyl-CoA levels are regulated to, in turn, control histone acetylation is under intense investigation, and holds promise for increased understanding of the molecular mechanisms adapting gene expression to internal and external stimuli. We studied the ...
