Experimental details: Immunofluorescent analysis of ATG7 showing staining in the cytoplasm of U-251 cells. U251 cells were treated with Chloroquine (50uM, 16h), fixed with 4% PFA (20 min) and permeabilized with Triton X-100 (0.2%, 30 min). Cells were probed with an ATG7 polyclonal antibody (Product # PA5-35203) (1:100, 2h at room temperature) followed by detection using a fluorescent conjugated secondary antibody (green) (1:1000, 1h). Nuclei were stained with Hoechst 33342 (blue) (10 µg/mL, 5 min).

Experimental details: Fig. 1 OHCs and IHCs expressed the highest levels of Atg7 in the cochlea. A Representative immunoblot of Atg7 protein in the cochlea. B Expression of the Atg7 gene was analyzed by RT-PCR. C Atg7 was evident in OHCs and IHCs in the cochlear cryosections. D , E Atg7 puncta were distributed throughout the OHC cell bodies as indicated in the infracuticular, nuclear, and basal pool sections. N = 6 for each group (western blot: N = 3). Scale bar: A - C : 5 mum; D , E : 10 mum.

Experimental details: Fig. 2 Abnormal autophagy in Atg7-deficient OHCs. A Representative immunostaining images showing efficient knockout of Atg7 in the OHCs and not in the IHCs. B Western blot showed that Atg7 was largely suppressed in the cochlear whole mount of Prestin Cre/+ Atg7 flox/flox mice. C Representative immunoblots showing elevated P62, increased LC3-I, and decreased LC3-II/LC3-I ratio. D P62 accumulated in Atg7-deficient OHCs, showing a colorful mosaic pattern when co-stained with myosin 7a. E P62 aggregated in the mutant OHCs, especially at middle and basal turns. An OHC in the basal turn was extruded from the sensory epithelium (white arrowhead). N = 6 for each group (western blot: N = 3). Scale bar: 10 mum.
