Global Lactylation Profiling Reveals Lactate-Driven Regulatory Mechanisms Promoting Tumor Progression in Oral Carcinoma

Cancer cells often rely on aerobic glycolysis for metabolism, and lactylation, a newly discovered post-translational modification, significantly impacts molecular processes. This study comprehensively analyzes lactylation's role in oral squamous cell carcinoma (OSCC), providing initial insights into its impact on progression. Six pairs of OSCC tissues underwent lactylation modification sequencing. 2,765 lactylation modification sites on 1,033 proteins were identified in OSCC, indicating its widespread presence. These modifications influenced metabolic activities, molecular synthesis, and transport.
