Therefore, for the PLEKHA7 overexpression (OE-PLEKHA7) experiment, metastasis-derived GC cell lines (MKN74 and SGC7901) were infected with lentivirus expressing PLEKHA7 to assess the effect of PLEKHA7 on GC cell migration and invasion ability (Fig. 2B). This evidence concerns the gene PLEKHA7 and gastric cancer.
