HSA-PEI-pcDNA-Apoptin reduces the viability and induces the apoptosis of MCF-7 cells. (A) MTT assays demonstrated that the viability of MCF-7 cells was reduced following transfection with the HSA-PEI-pcDNA-Apoptin expression vector. OD value of three groups. (B) Flow cytometric analysis indicated that MCF-7 cell apoptosis was significantly reduced following transfection with HSA-PEI-pcDNA-Apoptin. Data are presented as the mean ± standard deviation of triplicate experiments. *P<0.05 vs. control. HSA, human serum albumin; PEI, polyethylenimine; OD optical density.
