MTOR and neoplasm: Numerous scientific research studies indicate the close relationship between the tumor micro-environment with autophagy pathway, as well as with the inducted anti-neoplastic immune reaction, in many malignancies, including GC.The influential characteristics of autophagy open up new horizons for the evolution of new anti-cancer substances.Some of the most remarkable autophagy inductors are Rapamycin inductors, including the inhibitors of mTOR, rapalogs, and Rapamycin analogs [84].
