Histone lactylation (Hla) is a metabolically stress-related histone modification that featured in specific gene expression regulation. However, the role of Hla in the pathogenesis of lung adenocarcinoma (LUAD) remains unexplored. Through bioinformatics analysis, we found that BZW2 exhibited an elevated level of expression in LUAD tissues, which was associated with a poor prognosis. Flow cytometry and TUNEL assay were used to analyze the apoptosis of LUAD cells and tissues, respectively. The effect of the cell function experiment on the LUAD cell phenotype was analyzed. An XF 96 Extracellular Flux Analyzer measured the ECAR value, and kits were used to detect lactate production and glucose consumption. Animal experiments were performed for further verification. Cell experiments showed that BZW2 fostered the malignant progression of LUAD by promoting glycolysis-mediated lactate production and lactylation of IDH3G. In a compelling in vivo validation, the inhibition of Hla could suppress the malignant progression of LUAD. Knockdown of BZW2 combined with 2-DG treatment significantly repressed tumor growth in mice. BZW2 could regulate the progression of LUAD through glycolysis-mediated IDH3G lactylation, offering a theoretical basis for the targeted treatment of LUAD with glycolysis and Hla.
