Cell viability was detected by an MTT assay. In brief, the cells were incubated on a 96-well plate until 80% cell confluence and then subjected to transfection and doxorubicin treatment. After incubation, cell viability was analyzed using a Cell Proliferation Kit 1 (MTT) (Sigma-Aldrich). MTT solution was added to each well and cultured for 4 h. The reaction was stopped, and DMSO was added to dissolve formazan crystals. The final mixture was analyzed using an enzyme-linked immunometric meter at 490 nm.
