  • Materials and Methods
  • Fig. S1. SLC7A11 expression is increased in the tumor edge.
  • Fig. S2. SLC7A11 expression is stable in the PDX-GBM xenoline glioma model.
  • Fig. S3. Medium from SXC-expressing gliospheres causes intracellular Ca2+ increases in neurons.
  • Fig. S4. SXC-mediated glutamate release causes neuronal death by glutamate receptor overstimulation.
  • Fig. S5. SXC-expressing tumors induce peritumoral neuronal cell loss.
  • Fig. S6. Contralateral brain has abundant NeuN+ neurons and GFAP+ astrocytes.
  • Fig. S7. Intracranially injected astrocytes do not cause neuronal cell loss or change in SXC expression of surrounding tissue.
  • Fig. S8. SXC-expressing gliomas proliferate faster and are more invasive.
  • Fig. S9. SXC-expressing gliomas demonstrate an invasive phenotype.
  • Fig. S10. Peritumoral neurons have similar action potential thresholds to neurons in sham-injected control cortex.
  • Fig. S11. SXC is variably expressed in different grades of glioma.
  • Fig. S12. MRS detection of glutamate is reproducible and shows rebound peak after SAS administration.
  • Fig. S13. EEG traces from glioma patients show abnormal activity.
  • Table S1. Demographic and clinical data for patients in MRS clinical trial.
