FIG 2 .

Activation of let-7i or miR-30b depended on viral dose and active replication. NHBE cells were inoculated with live RSV that was not UV inactivated or with UV-inactivated RSV. RNAs were harvested 1, 24, or 48 h later and were assayed for miRNA expression by real-time PCR. The relative fold change of let-7i or miR-30b was calculated by normalizing values against the GAPDH control in comparison to mock-infected cells. Three technical replicates of three biological replicates were performed. Data are plotted as means; error bars represent the standard errors of the means. PI, postinoculation.
