Figure 3. Defective autophagy sensitizes mammary tumor cells to ER stressors and proteasome inhibitors.
MTT assays showing sensitivity of Bcl-2-expressing beclin 1+/+ (blue) and beclin 1+/− (red) iMMECs to increasing concentrations of epoxomycin (left column) and tunicamycin (right column) after 2 days of metabolic stress (A), and after a 2-day recovery following metabolic stress for 3 days (B) and 5 days (C). Data is presented as mean ± SD. p-values were calculated by two way ANOVA.
