POSTN secreted from GSCs promotes GSC self-renewal and tumor growth via activation of the αVβ3/PI3K/AKT/β-catenin/FOSL1 pathway [GSCs_RNA-seq]
Ontology highlight
ABSTRACT: Glioblastoma (GBM), classified as a grade 4 glioma, is the most prevalent intrinsic malignancy of the central nervous system. Glioblastoma stem cells (GSCs) are small populations of GBM cells with self-renewal and multilineage differentiation capabilities and are considered responsible for the tumorigenesis and development of GBM. GSCs also exhibit radiation resistance, chemoresistance, and angiogenic and invasive properties, which are correlated with poor outcomes in GBM patients. Therefore, targeting GSCs constitutes a promising approach for treating GBM patients. Our findings revealed that POSTN secreted from GSCs promotes GSC self-renewal and tumor growth via activation of the αVβ3/PI3K/AKT/β-catenin/FOSL1 pathway.
