The relative expressions of MEKK1mRNA and protein in MCF-7 and MCF-7/ADR cells after miRNA transfection. a qRT-PCR showing the mRNA expression of MEKK1 in MCF-7and MCF-7/ADR cells. b Western blot and densitometric analysis showing the protein expression of MEKK1 in MCF-7 cell and MCF-7/ADR cell. c The stability assay of MEKK1 mRNA. MCF-7/ADR cells were harvested at 0, 2, 4, 6 and 8 h after treatment with 5 mg/mL actinomycin D. Residual mRNAs was detected by qRT-PCR. All graphs show means ± S.D. of three independent experiments.
