Furthermore, the correlations among CTLs, T-cell dysfunction, survival, and SLC19A1 expression were overviewed, revealing significant associations in neuroblastoma, acute myeloid leukemia (AML), metastatic melanoma, uterine corpus endometrial carcinoma, and triple-negative BRCA (Figure 7A). Here, SLC19A1 is linked to uterine corpus endometrial carcinoma.
