a SGC-7901, MKN-45 and AGS had a higher Apelin expression levels compared GES-1 by western blot assay. b Apelin treatment (50 and 100Â ng/mL) for 8Â h did not affect the proliferation rates in GC cell lines and non-cancer cell line GES-1. c and d The migration and invasion abilities of GC cell lines were significantly increased by Apelin treatment (50 and 100Â ng/mL for 8Â h, respectively)
