Figure 1. Bioactive mistletoe miRNAs screen for cytotoxic effects. Cells were seeded in 48-well plates at a density of 2 × 104 cells per well and transfected with various miRNA mimics at a concentration of 20 nM. Cell viability was determined by MTT assay 72 h after transfection. n = 3. Compared with cells treated with NC miRNA, *P < 0.05; **P < 0.01; ***P < 0.001; **** P < 0.0001.
