Abstract

Hypoxia induces the expansion of glioblastoma stem cells (GSCs), but the mechanism underlying it is still unclear. Here, we supply evidence that hypoxia-inducible factor-1α (HIF-1α) induced activation of Notch pathway is essential for hypoxia-mediated maintenance of GSC. Either depletion of HIF-1α or inactivation of Notch signaling partly inhibits the hypoxia-mediated maintenance of GSC. Further data suggest a role for HIF-1α in the interaction and stabilization of intracellular domain of Notch (NICD), and activation of Notch signaling. The mRNA level of HIF-1α and Notch target gene FABP7 was elevated in GSC. And the STAT3 pathway responsible for the HIF-1α gene transcription, the phosphatidylinositol 3-kinase-Akt and ERK1/2, both of which are contributed to HIF-1α protein translation, are also preferentially activated in GSC. Inhibition of these pathways partly reduces the hypoxia-induced activation of the Notch pathway and subsequent GSC maintenance. Taken together, our findings suggest that HIF-1α requires Notch pathway to drive the maintenance of GSC. The activated regulation of HIF-1α makes GSC more sensitive to hypoxia-mediated maintenance. These findings enhance our understanding of mechanism of hypoxia-mediated GSC expansion and provide HIF-1α as an attractive target for glioblastoma therapy.

    From Revisiting the HIF switch in the tumor and its immune microenvironment. (2022) · cites this paper as [49]

    The Results (page unavailable) identify CD133-positive cells as enriching glioblastoma stem cells, and the Discussion (page unavailable) reports that glioblastoma-derived tumor spheres show relative resistance to doxorubicin. The copy does not place these cells in a perivascular niche, identify CD44-positive cells, or say they cause GBM recurrence. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
