miR-1908-3p promotes MDA-MB-231 cell proliferation, migration and invasion. a The expression of miR-1908-3p in MDA-MB-231 cell were affected by transfection of miR-1908-3p mimics or inhibitor. b & c CCK8 and SRB assay were used to evaluated the proliferation of MDA-MB-231 cells following transfection with miR-1908-3p mimics or inhibitor. d The migration ability of MDA-MB-231 cells with miR-1908-3p mimics or inhibitor transfection. e The invasion ability of MDA-MB-231 cells with miR-1908-3p mimics or inhibitor transfection. Relative quantification of miR-1908-3p expression were calculated with the 2-∆∆Ct method. *, p < 0.05; **, p < 0.01; ***, p < 0.001
