Figure 3From: ISG15 facilitates cellular antiviral response to dengue and west nile virus infection in vitroIfnb1 expression in virus infected cells after gene silencing. Ifnb1 gene expression level was measured by quantitative RT-PCR and normalized to mouse beta-actin gene. Results are expressed as the mean + the SEM. * p < 0.05 and ** p < 0.01. Representative results from at least 3 independent experiments.Back to article page
