摘要
Reversible,spatial,and temporal regulation of metabolic reprogramming and epigenetic homeostasis are prominent hallmarks of carcinogenesis.Cancer cells reprogram their metabolism to meet the high bioenergetic and biosynthetic demands for vigorous proliferation.Epigenetic dysregulation is a common fea-ture of human cancers,which contributes to tumorigenesis and maintenance of the malignant phenotypes by regulating gene expression.The epigenome is sensitive to metabolic changes.Metabolism produces various metabolites that are substrates,cofactors,or inhibitors of epigenetic enzymes.Alterations in metabolic pathways and fluctuations in intermediate metabolites convey information regarding the intracellular metabolic status into the nucleus by modulating the activity of epigenetic enzymes and thus remodeling the epige-netic landscape,inducing transcriptional responses to heterogeneous metabolic requirements.Cancer metabolism is regulated by epigenetic machinery at both transcriptional and post-transcriptional levels.Epigenetic modifiers,chromatin remodelers and non-coding RNAs are integral contributors to the regulatory networks involved in cancer metabolism,facilitating malignant transformation.However,the significance of the close connection between metabolism and epi-genetics in the context of cancer has not been fully deciphered.Thus,it will be constructive to summarize and update the emerging new evidence support-ing this bidirectional crosstalk and deeply assess how the crosstalk between metabolic reprogramming and epigenetic abnormalities could be exploited to optimize treatment paradigms and establish new therapeutic options.In this review,we summarize the central mechanisms by which epigenetics and metabolism reciprocally modulate each other in cancer and elaborate upon and update the major contributions of the interplays between epigenetic aber-rations and metabolic rewiring to cancer initiation and development.Finally,we highlight the potential therapeutic opportunities for hematological malig-nancies and solid tumors by targeting this epigenetic-metabolic circuit.In summary,we endeavored to depict the current understanding of the coordi-nation between these fundamental abnormalities more comprehensively and provide new perspectives for utilizing metabolic and epigenetic targets for cancer treatment.
