To determine whether SLC31A1 gene expression is higher in glioma patients, we analyzed data from different datasets and levels; at first we analyzed the SLC31A1 gene expression in glioma samples using the data from the TCGA dataset and compared it to the normal tissue samples from the GTEx dataset (Fig. 1A) (N = 1157, T = 689). The gene discussed is SLC31A1; the disease is central nervous system cancer.
