In order to further explore the function of SLC19A1, the correlation between the expression of SLC19A1 and cancer stemness was analyzed (Figure 3A), demonstrating that the expression of SLC19A1 correlated positively with cancer stemness in UVM, MESO, SARC, LGG, HNSC, GBM, LGG, and BLCA but negatively in TGCT, CHOL, KIPAN, THYM, PCPG, and CESC (Figure 3A). This evidence concerns the gene SLC19A1 and cancer.
