Different types of amino acid transporters are also upregulated in cancer tissues: SLC1A5 (sodium-dependent neutral amino acid transporter type 2, which transports glutamine, asparagine, alanine, serine, and cysteine)32, SLC7A5 [LAT1 (large neutral amino acid transporter small subunit 1), which transports phenylalanine, tyrosine, leucine, histidine, methionine, and tryptophan]33, and SLC6A14 (sodium-dependent and chloride-dependent transporter, which mediates neutral and cationic amino acid uptake)34. This evidence concerns the gene SLC38A7 and cancer.
