Histone Lactylation-Driven GPD2 Mediates M2 Macrophage Polarization to Promote Malignant Transformation of Cervical Cancer Progression

Cervical cancer (CC) is the most common cancer in women. This study aims to explore the molecular mechanism of lactate secreted by CC cells modulating macrophage polarization in CC via histone lactylation. Normal cervical epithelium (NCE), low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), and cervical squamous cell carcinoma (CESC) were collected to assess H3K18la level and macrophage infiltration. Macrophages were incubated with SiHa cell-derived conditioned medium to detect M1 and M2 markers. NCE, HSIL, and CESC samples were used for ChIP-seq of H3K18la. Histone lactylation-dirven
