To further explore the potential biological role of PRMT7 in GC cells, we selected MGC-803 and AGS cells with moderate PRMT7 expression for transfection with siRNA and plasmid DNA based on the results presented in Fig. 1C. The knockdown or overexpression efficiency of PRMT7 was assessed using RT-qPCR and western blotting. Here, PRMT7 is linked to gastric cancer.
