PSCs and cancer cells in pancreatic cancer TME release ATP, which activates the P2X7 receptor, promoting PSC proliferation, collagen secretion, and IL-6 secretion, and P2X7R-conditioned cultures also stimulate PSCs to activate the JAK/STAT3 signaling pathway in cancer cells, leading to pancreatic cancer cell migration, which is inhibited by tocilizumab [99]. This evidence concerns the gene STAT3 and familial pancreatic carcinoma.
