Effect of Huaier aqueous extract on DARC protein expression in (a) MCF-7 cells and (b) MDA-MB-231 cells after treatment with different concentrations (4 or 8 mg/ml) of Huaier aqueous extract for 48 h. Western blotting was used to measure protein expression. The histogram shows the grey level change in different conditions. ∗P < 0.05 compared with 4 mg/ml group at the same time point.
