Figure 1 Tumors Trigger Non-autonomous Autophagy Both Locally and Systemically (A) Drosophila larvae harboring RasV12, scrib−/− tumors (green) in eye-antennal discs (EAD) undergo systemic autophagy. Tumors can metastasize from brain lobes (BL) and/or EAD into ventral nerve cord (VNC). (B) Local non-autonomous autophagy (NAA) fuels RasV12, scrib−/− growth and metastasis. JNK, Yki, and autocrine JAK-STAT signaling activated by Upd/IL-6 trigger NAA. NAA may contribute to tumor growth by providing nutrients to tumors, including through the amino acid transporter Slimfast.
