Non-autonomous autophagy (NAA) fuels tumor growth. RasV12 scrib tumor cells (left) generate an unknown signal, which triggers NAA in neighboring wild-type cells (right). Released amino acids such as Alanine (Ala), but likely also others, are transported into RasV12 scrib tumor cells where they may be used as alternative carbon source for proliferation and invasion, triggering tumor growth
