KRAS and infection: Repeated experiments (summarized in Supplementary Figure 2), with different readouts of infection (e.g., expression of NS3 protein as measured by immunoblotting, or infectious virion production as measured by plaque assay) revealed a lack of effects for (i) cholesterol depletion with methyl-β-cyclodextrin (15 mM), (ii) amiloride (1 mM), (iii) latrunculin (1 μM).
