Figure 8. Autophagy inhibitors enhance cell death in iopromide-treated cells. HEK 293 cells were pretreated with (A) 1 mM 3-methyladenine (3-MA) and (B) 100 nM bafilomycin A1 (Baf) for 4 h, and then incubated with 50 mgI/ml iopromide for 48 h. Cell viability was assessed using the MTT assay. The results are expressed relative to those of the untreated control and values are presented as mean±SE (n=3) (***p<0.001).
