Inhibiting LAT1 can pave a way forsuppressing tumor growth; this approach can also be exploited forthe delivery of antineoplastic drugs into cancer cells via a prodrugstrategy.5,9 Regarding the overexpression pattern ofLAT1 in various cancers, developing radiolabeled selective LAT1 ligandscould be one way to diagnose the presence of malignant cells in peripheraltissues.12,13. This evidence concerns the gene SLC7A5 and cancer.
