PGK1-driven histone lactylation fuels MDSC-driven immune evasion and tumor progression in triple-negative breast cancer.
Functional assays demonstrated that PGK1-driven glycolysis in TNBC cells promotes lactate accumulation and H3K18la, which subsequently induce transcriptional activation of CCL5 and recruitment of MDSCs, thereby impairing CD8+ T cell function and fostering an immunosuppressive tumor microenvironment that facilitates imm...
