IL13RA2 and pancreatic neoplasm: qRT-PCR analysis identified five pancreatic cancer cell lines (HS766T, MIAPaCa2, KLM, SW1990 and BxPC3), which expressed high levels of IL-13Rα2 mRNA, and six cell lines (Panc-1, ASPC-1, HPAF-II, Mpanc96, PK-1 and Capan-1) expressed low levels IL-13Rα2 mRNA (negative cell line) (Figure 1A).
