Table 1. Viability and miR222 expression. Percentage of cellular viability, measured using the FDA/EtBr method, of Balb/c 3T3 cells on day 4 (initiation phase) of the transformation assay. Cells were treated with metal mixture or transfected with antimiR-222 and treated with the metal mixture; n=3, two-tailed unpaired t-test. Relative expression of mmu-miR-222 in Balb/c 3T3 cells on day 4 (initiation phase) of the transformation assay. Cells initiated with the metal mixture. The results of RTqPCR are represented in terms of 2^-∆∆CT; endogenous control: snRNA U6, n=3, mean±s.e., two-tailed unpaired t-test, ***p<0.001
