The result from MTT, colony-formation, and Transwell assays showed that MGC-803 cells co-transfected with pcDNA3.1-RP11-138J23.1 and VAV3 siRNAs could partially reverse RP11-138J23.1-induced GC cell proliferation and metastasis (Figures 7E–G). The gene discussed is VAV3; the disease is gastric cancer.
