Hypoxia-induced TGFBI maintains glioma stem cells by stabilizing EphA2.

ABSTRACT: Rationale: Glioma stem cells (GSCs) have emerged as pivotal drivers of tumor malignancy, sustained by various microenvironmental factors, including immune molecules and hypoxia. In our previous study, we elucidated the significant role of transforming growth factor beta-induced protein (TGFBI), a protein secreted by M2-like tumor-associated macrophages, in promoting the malignant behavior of glioblastoma (GBM) under normoxic conditions. Building upon these findings, the objective of this study was to comprehensively explore the crucial role and underlying mechanisms of autocrine TGFBI in GSCs under hypoxic conditions. Methods: We quantified TGFBI expression in glioma specimens and datasets. In vitro and in vivo assays were employed to investigate the effects of
