SLC1A5 and pancreatic neoplasm: Immunohistochemical analysis of a subcutaneous BxPC3 (human pancreatic cancer cell) tumour in a mouse with anti-human/murine ASCT2 antibody revealed that ASCT2 was distinctly overexpressed in the tumour compared to normal tissues (Fig. 2a, Supplementary Fig. S13), suggesting that ASCT2 can be a potential target transporter on cancer cells.
