摘要
How cells sense and respond to environmental changes is still a key question.It has been identified that cellular metabolism is an important modifier of various epigenetic modifications,such as DNA methylation,histone methylation and acetylation and RNA N6-methyladenosine(m6A)methylation.This closely links the environmental nutrient availability to the maintenance of chromatin structure and gene expression,and is crucial to regulate cellular homeostasis,cell growth and differentiation.Cancer metabolic reprogramming and epigenetic alterations are widely observed,and facilitate cancer development and progression.In cancer cells,oncogenic signaling-driven metabolic reprogramming modifies the epigenetic landscape via changes in the keymetabolite levels.In this review,we briefly summarized the current evidence that the abundance of key metabolites,such as S-adenosyl methionine(SAM),acetyl-CoA,α-ketoglutarate(α-KG),2-hydroxyglutarate(2-HG),uridine diphospho-N-acetylglucosamine(UDP-GlcNAc)and lactate,affected by metabolic reprogramming plays an important role in dynamically regulating epigenetic modifications in cancer.An improved understanding of the roles of metabolic reprogramming in epigenetic regulation can contribute to uncover the underlying mechanisms of metabolic reprogramming in cancer development and identify the potential targets for cancer therapies.
