Autophagy and ionizing radiation in tumors: The “survive or not survive” dilemma

Abstract excerpt

Autophagy is a so-called "self-eating" system responsible for degrading long-lived proteins and cytoplasmic organelles, whose products are recycled to maintain cellular homeostasis. This ability makes autophagy a good candidate for a survival mechanism in response to several stresses, including the tumor cell transformation. In particular, recent studies suggested that autophagy functions as a pro-death mechanism...
