GABARAP and neoplasm: Using a transgenic line that expresses a tandem autophagy reporter (UAS pGFP-mCherry-Atg8a) (Nezis et al, 2010) under the control of a muscle-specific driver (MhcGAL4), we found the ratio of mCherry vs. EGFP was significantly elevated in tumour-bearing animals (QRasV12scribRNAi) at 6 days AEL (Fig. EV3N–P).
