Targeting arginine auxotrophy in pancreatic cancer cells using human recombinant arginase I-induced arginine deprivation. (c2017) حسب Khalil, Nathalie

"…We have established that autophagy, a process of cellular destruction activated in response to arginine deprivation, can be the leading cause of cell death at late drug incubation times. Hence, our study demonstrates that HuArgI (Co)-PEG5000 is a novel, potent and selective potential therapeutic approach for PC.…"
