Figure 4. miR-9-5p inhibitor rescues the effect of ZNRD1-AS1 knockdown on malignant characteristics and apoptosis. miR-9-5p inhibitor was cotransfected into MGC803 and BGC823 cells; with cotransfection of siZNRD1-AS1 and miR-NC inhibitor as control. Cell proliferation (A) and apoptosis (B) were analyzed by CCK8 assays and flow cytometry, respectively. Cell invasion (C) and migration (D) were analyzed by Transwell assays. Left panels show representative micrographs. Right panels show statistical results. *p <0.05, for siZNRD1-AS1 + miR-9-5p inhibitor vs. siZNRD1-AS1 + miR-NC inhibitor.
