Furthermore, representative immunohistochemical (IHC) staining for SLC31A1 and ATP7B in high- and low-grade glioma from the Human Protein Atlas (Pontén et al., 2008) (https://www.proteinatlas.org/) was utilized to validate the results (Supplementary Figures S2C, S2D). The gene discussed is SLC31A1; the disease is glioma.
