Summary: Given the clinical challenge of advanced, therapy-resistant prostate cancer (PCa), this study aimed to identify novel molecular drivers. Using transcriptomic data from the TCGA and GEO databases, combined with WGCNA, differential expression analysis, and LASSO regression, APOBEC3C (A3C) was identified as a key candidate, whose downregulation in PCa tumors correlated with advanced T stage, higher Gleason scores, and poor survival. Bioinformatic analysis linked high A3C expression to an anti-tumor immune microenvironment (e.g., increased CD8+ T cell infiltration and reduced M2 macrophages). In vitro assays confirmed that A3C overexpression suppressed PCa cell proliferation, migration, and invasion, while its knockdown promoted these malignant phenotypes. Mechanistically, A3C enhances the expression levels of STING1 and its downstream molecules, including Caspase1, IL-18, and IL-1β, upregulating DNA damage protective genes (GSTP1 and GPX3) and enhancing cell cycle regulator GAS1 expression. Collectively, this study establishes A3C as a PCa suppressor that impedes tumor progression via multiple key pathways.
