Metabolic reprogramming in melanoma: an epigenetic point of view

Metabolic reprogramming and epigenetic alterations are fundamental hallmarks of cancer cells, contributing to adaptation, progression, and resistance. In melanoma, high metabolic-epigenetic plasticity enables the rapid modulation of cell states in response to environmental and therapeutic pressures. Recent studies have highlighted a bidirectional crosstalk between cellular metabolism and epigenetic regulation. Epigenetic modifications influence the transcriptional control of metabolic genes, thereby shaping metabolic phenotypes. Conversely, specific metabolites are essential cofactors or substrates for epigenetic enzymes, directly modulating the epigenome. Understanding the intricate mechanisms of this interaction offers opportunities for the development of innovative tumor management that combines epigenetic, metabolic, and therapy interventions. In this review, we summarize the latest evidence on the role of the metabolism–epigenetics axis in melanoma and discuss its potential clinical implications, aiming to provide a comprehensive overview of metabolic/epigenetic interconnections.
