ZNF70 is a candidate target gene of miR-1269a and serves as a tumor suppressor in gastric cancer cells. (A) Sequence alignment of miR-1269a and putative ZNF70-3′UTR. (B) Western blot analysis of expression levels of ZNF70 in HGC-27 and MGC-803 cells that were transfected with miR-control, miR1269a mimics and miR-1269a-variant mimics and their inhibitors. GAPDH served as the loading control. (C) Western blot analysis of ZNF70 in ZNF70-siRNA-transfected cells. GAPDH served as the loading control. (D) The effects of ZNF70 on miR-1269a-mediated HCC proliferation as analyzed by cell-counting kit-8 assay. *P<0.05, **P<0.01 and ***P<0.001. ZNF70, zinc-finger protein 70; siRNA, small-interfering RNA; miRNA, microRNA; OD, optical density; UTR, untranslated region.
