SLC43A1 and cancer: Amino acid transporters such as L-type amino acid transporter 1 (LAT1) [3], L-type amino acid transporter 3 (LAT3) [4], system ASC transporter 2 (ASCT2) [5], amino acid transporter system B0,+ (ATB0,+) [6], and system xc− transporter-related protein (xCT) [7] have been reported to increase expression in cancer cells.
