SLC7A5 and head and neck squamous cell carcinoma: We have previously shown that 2-aminobicyclo-(2,2,1)-heptane-2-carboxylic acid (BCH), a classical inhibitor of system L amino acid transporters including LAT1, in combination with the platinum drug cisplatin suppresses the growth of a head and neck squamous cell carcinoma cell line more strongly than by their single treatment [35].
