The contributions of SNAT1 and SNAT2 were confirmed using a SNAT2 knock-out HCC1806 clone (D126) and comparing it to the parental ASCT2 knock-out cell line (C10) that we have previously used to analyze the role of ASCT2 in cancer cells (Broer et al., 2019). The gene discussed is SLC38A2; the disease is cancer.
