Abstract
A link between epigenetics and metabolism was initially recognized because the cellular metabolic state is communicated to the genome through the concentration of intermediary metabolites that are cofactors of chromatin-modifying enzymes. Recently, an additional interaction was postulated due to the capacity of the epigenome to store substantial amounts of metabolites that could become available again to cellular metabolite pools. Here, we focus on histone acetylation and review recent evidence illustrating this reciprocal relationship: in one direction, signaling-induced acetyl-coenzyme A (acetyl-CoA) changes influence histone acetylation levels to regulate genomic functions, and in the opposite direction histone acetylation acts as an acetate reservoir to directly affect downstream acetyl-CoA-mediated metabolism. This review highlights the current understanding, experimental challenges, and future perspectives of this bidirectional interplay.
期刊介绍：
For over 40 years, Trends in Biochemical Sciences (TIBS) has been a leading publication keeping readers informed about recent advances in all areas of biochemistry and molecular biology. Through monthly, peer-reviewed issues, TIBS covers a wide range of topics, from traditional subjects like protein structure and function to emerging areas in signaling and metabolism. Articles are curated by the Editor and authored by top researchers in their fields, with a focus on moving beyond simple literature summaries to providing novel insights and perspectives. Each issue primarily features concise and timely Reviews and Opinions, supplemented by shorter articles including Spotlights, Forums, and Technology of the Month, as well as impactful pieces like Science & Society and Scientific Life articles.
