Because the three autophagy-related genes identified in our screen mapped to two distinct steps of the process—formation of the isolation membrane for Atg9, or phagophore elongation for Atg7 and Atg8a, we questioned whether the tumour-suppressive effect was limited to these genes, or whether autophagy in general was necessary to limit RasV12-driven overgrowth of fly epithelial tissue. The gene discussed is ATG7; the disease is neoplasm.
