Figure 9. MiR-106b-5p suppresses IGSF10 expression by binding to its 3’-UTR. (A) Dual luciferase assay results show that miR-106b-5p directly targets the 3′-UTR of IGSF10. (B) Dual luciferase assay results show that relative luciferase activity is significantly repressed in LAUD cells co-transfected with miR-106b-5p and wild type 3′-UTR of IGSF10 compared to those co-transfected with miR-106b-5p and mutated 3′-UTR of IGSF10 (P < 0.05). (C) RT-qPCR analysis shows expression levels of miR-106b-5p in A549 and PC9 cells transfected with non-specific control (miR-NC) or miR-106b-5p mimics. (D) Western blot analysis shows IGSF10 protein levels in A549 and PC9 cells transfected with non-specific control (miR-NC) or miR-106b-5p mimics. (E) MTT assay and (F) colony formation assays show proliferative ability of A549 and PC9 cells transfected with non-specific control (miR-NC) or miR-106b-5p mimics. (G) Transwell assay results show migration and invasion ability of A549 and PC9 cells transfected with non-specific control (miR-NC) or miR-106b-5p mimics. Results are shown as means ± SD; ^* p < 0.05, ^**p < 0.01, and ^***p < 0.001 vs. control group.
