Due to the lack of the follow-up information of colorectal cancer and glioma patients, we analyzed the TCGA datasets via Human Protein Atlas website (https://www.proteinatlas.org/), and found that Glut5 was highly expressed in the colorectal cancer patients with poor outcome (Figure S2E), while the result was not statistically significant for glioma patients (Figure S2F). This evidence concerns the gene SLC2A5 and central nervous system cancer.
