Atg8s are crucial for correct acidification of sequestered cargo. (A and B) WT, LC3 TKO, GBRP TKO, and hexa KO expressing YFP-Parkin and mtKeima were either untreated or treated with OA for indicated times and analyzed for (A) lysosomal-positive mtKeima using fluorescence microscopy (550 nm mtKeima; see Fig. S5 A for 2- and 8-h images), and (B) FACS as the percentage of 561 nm mtKeima positive cells (see Fig. S5 B for FACS plots). (C and D) Hexa KO cells expressing mtKeima and doxycycline (Dox)–inducible HA-LC3C or HA-GBRPL1 were pretreated with OA for 8 h. After being incubated with Dox, Wort, and OA for 6 h, the cells were analyzed by confocal microscopy (C) and FACS (D) for lysosomal-positive mtKeima (see Fig. S5, C and D). Data in B and D are mean ± SD from three independent experiments. ***, P < 0.001; ****, P < 0.0001 (one-way ANOVA). ns, not significant. Bars, 10 µm.
