Investigation of MANF regulation of glioma stemness via STAT3/TGF-β/SMAD4/p38 pathway based on pan-cancer analysis.
Background: Glioma, particularly glioblastoma, is a highly aggressive brain tumor with poor prognosis and limited treatment options. Recent research highlights the role of MANF (Mesencephalic Astrocyte Derived Neurotrophic Factor) in tumor biology, yet its specific mechanisms in glioma remain underexplored. This study aims to elucidate the role of MANF in glioma and its underlying mechanisms of action.
Methods: We conducted bioinformatics analysis using TCGA data to identify MANF-related pathways, followed by cellular assays and subcutaneous tumor models for functional validation. Experiments included Western blot and qRT-PCR analysis to investigate the effects of MANF on glioma cell proliferation, migration, and stemness gene expression.
Results: MANF was found to be highly expressed in tumor tissues and associated with poor prognosis in glioma patients. Endogenous MANF regulates tumor cells by modulating the TGF-β/SMAD4/p38 pathway, promoting stemness and enhancing malignant behaviors, including migration and invasion. Exogenous MANF, however, did not significantly affect stemness gene expression but contributed to glioma cell proliferation.
Conclusions: MANF emerges as a promising therapeutic target for glioma. This study clarifies MANF's specific mechanisms, offering insights into its potential for targeted glioma therapies.
