Fig. 3

Autophagy promotes cell survival independently of the proteasome activity (A) LysoIP performed after 3 h of 50 nM CPT (nM) or 1 μM CPT (μM) and the proteasome inhibitor bortezomib (BTZ) (n = 3). (B) Clonogenic assays performed simultaneously with low- or high-dose CPT (n = 3). Error bar, SEM. (C) LysoIP in S-phase HeLa cells after 3 h of 50 nM CPT and 1 μM ATR inhibitor VE-822 (ATRi) or 1 μM ATM inhibitor KU-55933 (ATMi) (n = 3). (D) Co-immunoprecipitation of p97-Strep in S-phase HEK293T cells after 1 h of 50 nM CPT (nM) or 1 μM CPT (μM) or 1 μM ATR inhibitor VE-822 (ATRi) (n = 2). (E) Immunofluorescence of protein aggregates using the Proteostat dye after 24 h of 50 nM CPT and quantification (n = 3). Scale bar, 10 μm. Error bar, SD. Two-way ANOVA. ∗∗p < 0.005; ∗∗∗p < 0.0005; ns, not significant. See also Figure S3.
