D: Plasma membrane recycling rate of WT EGFR in control, sgAtg7, or sgAtg16l1 glial shNf-1/shTp53 or EGFRvIII-expressing cells was assayed by cell surface biotinylation and successive applications of 2 ng/mL EGF treatments for 15 min Monensin treatment was added as indicated. Data information: 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<0.05, *** p<0.001.
