As previously mentioned in the Methods section, an in silico differential analysis of G6PC (G6PC1, G6PC2, G6PC3) (Figure 1A) and SLC37A (SLC37A1, SLC37A2, SLC37A3, SLC37A4) (Figure 1B) family members transcript levels was conducted on clinical samples from glioblastoma (GBM) and low-grade glioma (LGG), and compared to healthy brain tissues. This evidence concerns the gene SLC37A4 and low grade glioma.
