ASCT2 belongs to the group of system ASC, transporting alanine, glutamine, serine and cysteine along with other aliphatic amino acids.31 SLC3A2 is an essential transmembrane protein critical for activating LAT1/2/3, ASC1, BAT1 and xCT involved in amino acid transport.32–34 Supplementation of exogenous ASCT2-specific amino acids (glutamine and valine) led to improved metabolic activity and survival in plasma-treated tumour cells in Panc-1 and MeWo but not in SK-MEL-28 cells. This evidence concerns the gene SLC1A5 and neoplasm.
