Crosstalk between lactylation and RNA modifications in tumorigenesis: mechanisms and therapeutic implications.

Complex crosstalk occurs between protein and nucleic acid modifications, with lactylation, an emerging post-translational modification (PTM), being implicated in tumor progression. However, the mechanisms mediating the crosstalk between lactylation and RNA modifications and their roles in disease pathogenesis remain largely unresolved. In this review, we summarize current advances in the regulatory interactions between lactylation and RNA modifications, explore their functional implications in cancer biology, and discuss the therapeutic potential of targeting these modifications individually or in combination. This work aims to provide a comprehensive overview of their mechanistic involvement in cancer and to inform novel strategies for precision-targeted therapy.
