Tumor development can be characterized by the formation of hypoxic area deprived in nutrients. Due to their genetic instability, tumor cells can become resistant to this apoptotic condition. Among the resistance mechanisms, those involved in cell survival against amino acids restriction is poorly known. Amino acids deprivation is particularly deleterious as nine of them cannot be synthetized de novo. The aim of this work was to identify the mechanisms by which tumor cells can survive to long-term amino acids deprivation. For that purpose, we exerted a selective pressure on mouse embryonic fibroblast by exposing them to amino acids deprivation for several months. We generated clones able to survive and proliferate in deprived amino acids med...
