miR-520f-3p directly targets SOX9 in GC. The alignment of the miR-520f-3p sequence with that of predicted SOX9 binding sites. (B) SOX9 expression was assessed via qRT-PCR in HGC-27 and MKN-45 cells following miR-520f-3p or miR-NC transfection. (C) SOX9 levels were assessed via Western blotting in HGC-27 and MKN-45 cells following miR-520f-3p or miR-NC transfection (D) Dual-luciferase reporter assays were used to reveal a reduction in luminescence upon miR-520f-3p mimic co-transfection with the SOX9-Wt vector, without a comparable effect for the SOX9-mut vector in 293 cells. (E) GEPIA data indicated that SOX9 was increased in GC. (F) Measurement of SOX9 expression via qRT-PCR in 92 paired GC and normal gastric epithelial tissue samples. *P < 0.05; **P < 0.01; ***P < 0.001.
