The expression of the receptor for advanced glycation endproducts (RAGE) is permissive for early pancreatic neoplasia.

ABSTRACT: Pancreatic cancer is an almost uniformly lethal disease, characterized by late diagnosis, early metastasis, resistance to chemotherapy, and early mutation of the Kras oncogene. Here we show that the receptor for advanced glycation endproducts (RAGE) is required for the activation of interleukin 6 (IL-6)-mediated mitochondrial signal transducers and activators of transcription 3 (STAT3) signaling in pancreatic carcinogenesis. RAGE expression correlates with elevated levels of autophagy in pancreatic cancer in vivo and in vitro, and this heightened state of autophagy is required for IL-6-induced STAT3 activation. To further explore the intersection of RAGE, autophagy, and pancreatic carcinogenesis, we created a transgenic murine model, backcrossing RAGE-null mice to a spontaneous mouse model
