A database search using GlioVis, an expression database utilizing large-scale high-throughput whole genome analysis of human glioma, revealed that the expression level of SLC19A1 was slightly higher in glioblastoma than in non-cancer tissue, but no significant relationship with the outcome was noted (GlioVis; http://gliovis.bioinfo.cnio.es/, accessed on 6 August 2021) [32]. Here, SLC19A1 is linked to glioblastoma.
