To determine the functions of SLC39A10 in gastric cancer cells, we first knocked down SLC39A10 in AGS and MKN45 cells using two different siRNAs (si- SLC39A10-#1 and -#3) specifically targeting SLC39A10 and verified their inhibition efficiency by qRT‒PCR (Supplementary Fig. 4a) and western blotting (Fig. 3a). Here, SLC39A10 is linked to gastric cancer.
