Cancer cells adapt their metabolism to survive limited nutrient availability. Here, the authors show that in conditions of limited glucose or glutamine availability, pancreatic ductal adenocarcinoma cells can use collagen-derived proline to foster the TCA cycle and allow cell survival both in vitro and in vivo.
Kamerkar et al. have engineered exosomes that target KRASG12D (iExosomes) and have demonstrated the specificity and efficacy of iExosomes in targeting oncogenic KRAS in mouse models of pancreatic cancer.
