Overexpression of LAT1, but not CD98hc, was detected in uterine cervical and bile duct carcinomas, and that of CD98hc, but not LAT1, was noted in glioblastoma, bladder carcinoma, esophagus adenocarcinoma, and Chronophobe renal carcinoma (chRCC) (Supplementary Figure 2). Here, SLC3A2 is linked to bile duct carcinoma.
