GABPB1 (GA binding protein transcription factor subunit beta-1) is a transcription factor subunit that plays context-dependent roles in both normal and pathological processes. As a component of the GABP complex, GABPB1 regulates transcription by RNA polymerase II and functions in nuclear organization 1. GABPB1 acts as an upstream transcription factor for TERT in glioblastoma, where it modulates pentose phosphate pathway flux and metabolic outputs including lactate and glutathione levels 21. In cancer contexts, GABPB1 demonstrates oncogenic properties. It is highly expressed in non-small cell lung cancer where elevated expression correlates with poor prognosis in lung adenocarcinoma and promotes cell proliferation while suppressing tumor immunity 3. Conversely, GABPB1-related lncRNAs show tumor-suppressive functions: lncRNA GABPB1-AS1 inhibits hepatocellular carcinoma ferroptosis resistance by downregulating GABPB1 protein translation and reducing antioxidant capacity 4, while GABPB1-AS1 suppresses non-small cell lung cancer and renal cancer progression through miRNA interactions 56. Additionally, lncRNA GABPB1-IT1 is upregulated in ischemia-induced acute kidney injury where it promotes epithelial cell apoptosis 7, and GABPB1-AS1 is upregulated in prostate cancer with diagnostic potential 8. These findings suggest GABPB1's role varies substantially by tissue context and molecular interactions.
