摘要

As a primary brain cancer, glioma presents significant challenges in treatment and prognosis. Identifying reliable biomarkers is crucial for improving patient outcomes. This study focuses on the ABCC3 gene, exploring its function as a standalone predictive indictor and its correlation with immune infiltration and resistance to chemotherapy in glioma. A multi-faceted approach was adopted for this analysis. We scrutinized the RNA expression patterns of the ABCC3 gene across a spectrum of cancer types, with a concentrated focus on glioma. Our methodological arsenal included bioinformatics analysis, immunohistochemistry (ICH), western blot (WB), and cell counting Kit-8 (CCK8) assays. These techniques were instrumental in gauging the prognostic impact of ABCC3 and elucidating its associations with immune cell infiltration and chemotherapy resistance. The investigation revealed a significant elevated levels of ABCC3 in high grade glioma (HGG) tissues compared to lower grade glioma (LGG) tissues. Notably, upregulation of ABCC3 were associated with a shorter overall survival in patients with glioma. Furthermore, ABCC3 emerged as an independent factor in prognostication, with predictive capability for 1-, 3-, and 5-year survival rates. As far as immune response is concerned, ABCC3's expression correlates positively with the expression of several immune cells and checkpoint genes. The study also uncovered the role of ABCC3 in drug resistance, particularly regarding temozolomide (TMZ), a primary therapeutic agent in glioma treatment. The study reveals ABCC3 as a significant biomarker in glioma, associated with lower survival, enhanced immune infiltration, and increased resistance to chemotherapy. These findings emphasize its promise as a novel target for glioma therapies.
