Cell viability. After the first round of mock or siRNA transfection, (A) 105 cells were seeded, transfected the following day, and grown for 3 days, and the viable cells that excluded trypan blue were counted. (B) Cell viability was also monitored by MTT assay after 24 hours of growth. The data are expressed as percentage of the control mock-transfected cells. Mean and SD of 10 experiments. The asterisks indicate a significant difference (P < .05).
