IL13RA2 and familial pancreatic carcinoma: It has been demonstrated that high levels of IL-13Rα2 mRNA were expressed in SW1990, MIA-PaCa-2, KLM, HS766T, and BxPC3 pancreatic cancer cell lines [100,108], while extremely low expression of IL-13Rα2 was examined in normal pancreatic cells including fibroblasts and ductal epithelial cell lines.
