(A) HeLa cells were transfected with the indicated siRNAs and subsequently infected with VSV wt or LXXXL mutant at an MOI of 0.005 for 1 h. Virus titers in culture supernatants were determined at the indicated time points post infection. The results of a single representative experiment carried out with triplicate samples are shown and were confirmed in two separate experiments. (B) The experiment was carried out as described for panel (A) but relative titers measured at 12 h post infection are shown. The results represent the average of three independent experiments performed with triplicate samples. Titers measured for untransfected control cells were set to 1. Error bars indicate standard error of the mean (SEM). (C) Vero cells stably expressing human tetherin (Vero-Tetherin) or stably containing empty vector (Vero) were infected with VSV wt or mutant LXXXL. Viral titers in culture supernatants were determined at the indicated time points post infection. The results of a single representative experiment carried out with triplicate samples are shown and were confirmed in two separate experiments. (D) The experiment was carried out as described for panel (C) but relative titers measured at 12 h post infection are shown. The results represent the average of three independent experiments performed with triplicate samples. Titers obtained from the respective control Vero cells were set to 1. Error bars indicate SEM. One-way ANOVA with Bonferroni post-test analyses were performed (B and D) to test statistical significance between selected groups (***, p ≤ 0.001).
