Effect of HEIH knockdown on the proliferation of MDA-MB-231 cells. (A) The expression levels of HEIH in MDA-MB-231 cells following transfection of the cells with HEIH siRNA. (B) Cell viability was determined by the MTS assay. (C and D) Proliferative ability was evaluated by an EdU incorporation assay in MDA-MB-231 cells following transfection of the cells with HEIH siRNA. Data are presented as the mean ± SEM (n=3). *P<0.05, **P<0.01 vs. control; ^#P<0.05, ^##P<0.01 vs. si-NC. HEIH, high expression in hepatocellular carcinoma; siRNA, small interfering RNA; NC, negative control; lncRNA, long non-coding RNA.
