MiR-145 suppresses LSCC proliferation and invasion and promotes apoptosis by inhibiting MYO5A. (A) Proliferation rates of Hep-2 cells at various time points after transfection with either miR-145 mimic or an NC. (B) Proliferation rates of Hep-2 cells at various time points after transfection with either MYO5A siRNA or an NC. (C) Hep-2 cells were transiently transfected with miR-145 mimic or an NC and subjected to migration and invasion assays. Representative photographs and quantification are shown. Magnification: ×200. (D) Hep-2 cells were transiently transfected with MYO5A-specific or NC siRNA and subjected to migration and invasion assays. Representative photographs and quantification are shown. Magnification: ×200. (E) Representative graph of the percentage of Hep-2 cells in apoptosis after transfection with miR-145 mimic or an NC. (F) Representative graph of the percentage of Hep-2 cells in apoptosis after transfection with MYO5A-specific siRNA or an NC. (G) Caspase-3 activity in Hep-2 cells transfected with miR-145 mimic or an NC. (H) Caspase-3 activity in Hep-2 cells transfected with MYO5A-specific siRNA or an NC.
