miR-30c inhibition of cell migration and invasion is partially rescued by IER2. miR-30c expressing SMMC-7721 cells (A) and HepG2 cells (B) or indicated NC cells were transfected with pEZ-Lv105-IER2 (miR-30c + IER2, NC + IER2) or pEZ-Lv105-null (miR-30c + null, NC + null) and the transwell migration and invasion assays were then performed. The number of migrated and invaded cells in each condition was assessed by cell counting and expressed as the fold of NC + null transfected cells. The data represented the mean ± SD from three independent experiments. *p<0.05, relative to NC + null, and #p<0.05, relative to miR-30c + null.
