Figure 3. Chlorpromazine and monodansyl cadaverine block EspF/SNX9-induced membrane tubulation.
HeLa cells co-transfected with EGFP-EspF and mCherry-SNX9 were incubated with DMEM (Untreated), or DMEM with 0.1% DMSO, 60μM chlorpromazine (CPZ), 80μM dynasore, 10mM methyl-beta-cyclodextrin (MBCD), or 400μM monodansyl cadaverine (MDC). Inhibitor treatment did not affect expression levels of either transgene. Both EGFP-EspF and mCherry-SNX9 localized to tubules in all conditions except treatment with CPZ and MDC, in which case both proteins exhibited a punctate staining pattern. Images are representative of three independent experiments.
