The following experiments were performed in glial shNf-1/shTp53 glial cells serum starved 4 hr before assaying. Cells were expressing either Cas9 alone (control) or Cas9 and sgRNA targeting Atg7 (sgAtg7 #1 or #2). C: Cells transiently expressing YFP-Gal8 were stimulated with 20 ng/mL Alexa 555-EGF (555-EGF) for 15 min. Scale bar: 10 μm. D: Quantification of the percentage of YFP-Gal8-labelled vesicles that colocalise with 555-EGF in control or ATG7-deficient cells (in C). Data information: White arrows indicate colocalisation. Statistical analyses were performed on at least 3 independent experiments, where error bars represent SEM and p values represent a two-tailed Student's t test: NS p>0.05, ** p<0.01, *** p<0.001.
