Expression of IFITM proteins upon interferon induction.

<p>Expression of IFITM proteins was induced in Vero and 293T cells after treatment with Universal type-I IFN at both 1,000 or 10,000 U/ml concentrations for 24 h and compared with untreated cells. Total cell extracts were incubated with antibodies against IFITM1 <b>(</b>A), IFITM2 (B) and IFITM3 (C). Right side panels represent WB quantification by densitometry for each IFITM and are expressed as the mean±SD from three independent experiments. Statistical significance was evaluated by a one-way ANOVA followed by Bonferroni’s multiple comparison test. Differences are marked with asterisks as indicated (**<i>p</i><0.01; ***<i>p</i><0.001).
