The tumor microenvironment (TME) is characterized by distinct metabolic adaptations that not only drive progression but also profoundly influence immune responses. Among these adaptations, lactate, a key byproduct of aerobic glycolysis, accumulates in the TME and plays pivotal role regulating cellular metabolism cell function. Tumor-associated macrophages (TAMs), known for their remarkable functional plasticity, serve as critical regulators progression. Lactate modulates TAM polarization influencing M1/M2 phenotypic balance through diverse signaling pathways, while simultaneously driving reprogramming. Furthermore, lactate-mediated histone protein lactylation reshapes gene expression, reinforcing immunosuppressive properties. From therapeutic perspective, targeting lactate has shown promise reprogramming TAMs enhancing anti-tumor immunity. Combining interventions with immunotherapies may further augment treatment efficacy. This review underscores crucial regulation progression, highlighting its potential promising target cancer treatment.

Abstract Histone lactylation plays a crucial role in cancer progression, but its impact on breast (BC) tumorigenesis is still unclear. We utilized chromatin immunoprecipitation sequencing with H3K18la antibodies, transcriptomics of clinical BC samples, and proteomics ATAC-seq analyses vivo tumors to identify the genes regulated by transcription factor PPARD. qPCR Western blot assays were used detect expressions molecules. discovered that levels higher tissues compared adjacent non-cancerous tissues. promoted expression PPARD, which turn influenced AKT, not ILK. analysis revealed glycolysis cells enhanced accessibility. Additionally, we confirmed HDAC2 HDAC3 act as “erasers” for H3 lysine lactylation. During analysis, AKT-phosphorylation aerobic respiration inhibitor group exhibited an apparent disparity activity. Our study demonstrated changes downstream PPARD support cell survival under anaerobic conditions. accelerated proliferation promoting phosphorylation AKT. This highlights therapeutic potential targeting H3K18la/PPARD/AKT axis cancer, providing new insights into epigenetic regulation metabolism (Trial registration: The was approved Research Ethics Committee Shandong Provincial Third Hospital (KYLL-2023057; https://www.medicalresearch.org.cn/ )).
