Inhibition of miR-34c-3p in exosomes induced A549 cell migration by regulating integrin α2β1. a Migration of A549 cells was induced by transfection with miR-34c-3p inhibitor. b Data analysis of a. c A549 cell migration was inhibited by transfection with miR-34c-3p mimics. d Data analysis of c. ns no significance, *p < 0.05, **p < 0.01, and n ≥ 3. e Western blot of integrin α2β1 expression in A549 cells after transfection with miR-34c-3p mimics. f Reduction in the level of miR-34c-3p in exosomes upon transfection with a miR-34c-3p inhibitor in A549 cells. g Induction of A549 cell migration by miR-34c-3p inhibitor-exo. h Data analysis of Fig. 6g. i Western blot analysis of integrin α2β1 expression from different groups, and GAPDH was used as a control to normalize levels. ns no significance, *p < 0.05, **p < 0.01, ***p < 0.001, and n ≥ 3.
