Tumor heterogeneity is influenced by various factors including genetic, epigenetic and axis of metabolic-epigenomic regulation. In recent years, metabolic-epigenomic reprogramming has been considered as one of the many tumor hallmarks and it appears to be driven by both microenvironment and macroenvironment factors including diet, microbiota and environmental pressures. Epigenetically, histone lysine residues are altered by various post-translational modifications (PTMs) such as acetylation, acylation, methylation and lactylation. Furthermore, lactylation is suggested as a new form of PTM that uses a lactate substrate as a metabolic ink for epigenetic writer enzyme that remodels histone proteins. Therefore, preclinical and clinical attempts are warranted to disrupt the pathway of metabolic-epigenomic reprogramming that will turn pro-tumor microenvironment into an anti-tumor microenvironment. This paper highlights the metabolicepigenomic regulation events including lactylation and its metabolic substrate lactate in the tumor microenvironment.
