Linc-NORAD knockdown reduced cell migration and invasion. a Lnc-NORAD was knocked down by the si-NORAD interference RNA in MCF-7. Cells was transfected with a scrambled negative-control siRNA (si-nc) for comparison. b Cell proliferation rates were compared between the cells transfected with si-NORAD or si-nc. Lnc-NORAD knockdown by si-NORAD significantly inhibit MCF-7 breast cancer cells proliferation. c Comparison of proliferation of the MDA-MB-231 breast cancer cells transfected with si-NORAD or si-nc. d Si-NORAD significantly inhibit MDA-MB-231 cells proliferation. ***p < 0.001 vs the control
