The mechanisms and effects of lactylation modification in different kinds of cancers.

Lactylation, a recently identified post-translational modification, has garnered significant attention for its associations with various diseases, particularly its critical role in tumor progression and treatment. It is emerging as a potential clinical target. The elevated metabolic activity of cancer cells often leads to excessive lactate accumulation, a phenomenon termed the "Warburg effect", which is a hallmark of the tumor microenvironment. Recent research reveals that lactate is not merely a metabolic byproduct but also serves as a substrate for protein lactylation, influencing tumor development by regulating cellular signaling, gene expression, and immune responses. This dual role has become a focal point for scientists and clinicians seeking novel therapeutic strategies targeting lactate-related pathways. Despite growing interest, the detailed mechanisms and therapeutic applications of lactylation across different cancer types remain inadequately explored. This review synthesizes current findings on lactylation mechanisms in various tumors, highlights potential therapeutic targets, and offers new perspectives to advance cancer treatment.
