The mRNA expression of SLC19A1 was significantly higher than normal tissue in 14 types of cancers, including BLCA, BRCA, COAD, ESCA, HNSC, KIRC, KIRP, PAAD, PRAD, READ, SKCM, STAD, UCES, and UCS, while the opposite was shown in 9 other types of cancers, including ACC, GBM, KICH, LAML, LGG, LUAD, LUSC, OV, and THCA (Figure 1B). Here, SLC19A1 is linked to cancer.
