Particularly, focusing on the expression of membrane glucose transporters, we observed that, despite SLC2A1 gene (alias Glut1) is reported as the most abundant channel expressed in primary thyroid tumours and cell lines [43, 44], SLC2A3 gene (alias Glut3) display comparable expression levels and both genes show higher expression in BRAF- vs RAS-like tumours (Supplementary Fig. S1B), as confirmed by RNA-Seq data of healthy thyroids on GTEx database (Supplementary Fig. S1C). Here, SLC2A1 is linked to thyroid tumor.
