SOX4-Mediated Mechanisms in Cancer Progression

SOX4 is a member of the SOX (SRY-related HMG-box) transcription factor family that governs key aspects of cell fate, differentiation and developmental programmes. In cancer, aberrant expression of SOX4 drives multiple hallmarks of malignancy by orchestrating transcriptional networks that promote proliferation, survival, invasion and metastatic dissemination. Mechanistically, SOX4 interacts with co-factors such as EZH2 and HDAC3 to remodel chromatin and repress tumour-suppressive microRNAs, while simultaneously activating genes that induce epithelial–mesenchymal transition (EMT), angiogenesis and cell cycle progression. Its influence extends to the tumour microenvironment, where SOX4 modulates immune cell infiltration and polarisation, and contributes to drug resistance through interactions with signalling pathways including PI3K/AKT, Wnt/β-catenin and TGF-β. Context-dependent roles of SOX4 have emerged, with evidence that in certain tumour types it may induce cell cycle arrest and apoptosis. Across organ systems—from hepatocellular carcinoma and breast cancer to pancreatic and nasopharyngeal malignancies—SOX4 fulfils a pleiotropic function. The global significance of this factor is underscored by its association with poor prognosis and therapy resistance in diverse solid tumours, positioning SOX4 as a promising target for novel anticancer strategies.
