The glioblastoma (GBM) microenvironment is enriched in immunosuppressive factors that potently interfere with the function of cytotoxic T lymphocytes. Cancer cells can directly impact the immune system, but the mechanisms driving these interactions are not completely clear. Here we demonstrate that the polyamine metabolite spermidine (SPD) is elevated in the GBM tumor microenvironment.

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.
