ABSTRACT = {The fertile stroma in pancreatic ductal adenocarcinomas (PDACs) has been suspected to greatly contribute 
to PDAC progression. Since the main cell constituents of the stroma are fibroblasts, there is crosstalking(s) 
between PDAC cells and surrounding fibroblasts in the stroma, which induces a fibroblast proliferation burst. 
We have reported that several malignant cancer cells including PDAC cells secrete a pronounced level of 
S100A11, which in turn stimulates proliferation of cancer cells via the receptor for advanced glycation end 
products (RAGE) in an autocrine manner. Owing to the RAGE<sup>+</sup>
 expression in fibroblasts, the extracellular 
abundant S100A11 will affect adjacent fibroblasts. In this study, we investigated the significance of the paracrine axis of S100A11–RAGE in fibroblasts for their proliferation activity. In in vitro settings, extracellular 
S100A11 induced upregulation of fibroblast proliferation. Our mechanistic studies revealed that the induction is through RAGE–MyD88–mTOR–p70 S6 kinase upon S100A11 stimulation. The paracrine effect on 
fibroblasts is linked mainly to triggering growth but not cellular motility. Thus, the identified pathway might 
become a potential therapeutic target to suppress PDAC progression through preventing PDAC-associated 
fibroblast proliferation.},
