CXCL5 was a target of miR-4766-5p. a The binding sites between miR-4766-5p and CXCL5 were shown. b Dual luciferase activity of CXCL5-WT/MUT was tested in GC cell lines by performing dual luciferase reporter assays after transfected with miR-4766-5p mimics or miR-NC. c The expression of CXCL5 was examined with qRT-PCR in normal tissues and tumor tissues. d The mRNA level of CXCL5 was examined in GC cells through performing qRT-PCR. e The protein level of CXCL5 was examined in GC cells through performing western blot analysis. *P < 0.05 compared with the Normal, GES or miR-NC group
