Homeostatic iron regulatory protein drives glioblastoma growth via tumor cell-intrinsic and sex-specific responses.

Background: Glioblastoma (GBM) displays alterations in iron that drive proliferation and tumor growth. Iron regulation is complex and involves many regulatory mechanisms, including the homeostatic iron regulator () gene, which encodes the homeostatic iron regulatory protein. While is upregulated in GBM and correlates with poor survival outcomes, the function of HFE in GBM remains unclear.
