[Retracted] miR-451a Inhibited Cell Proliferation and Enhanced Tamoxifen Sensitive in Breast Cancer via Macrophage Migration Inhibitory Factor

Figure 4

Effect of miR-451a and miR-451a sponge on cell proliferation and colony formation of MCF-7 and LCC2 cells. Cell proliferation was examined by MTT assay for MCF-7 cells (a) and LCC2 cells (b) transfected with Lv-miR-451a, Lv-miR-451a sponge, or Lv-miR-451a NC. (c) Colony formation was examined for MCF-7 cells and LCC2 cells transfected with Lv-miR-451a, Lv-miR-451a sponge, or Lv-miR-451a NC. versus Lv-miR-451a NC (MCF-7); versus Lv-miR-451a NC (LCC2) (note: NC means negative control; Lv means lentivirus).
