In addition, we selected a normal pancreatic ductal epithelial cell (HPDE6.C7) and a panel of pancreatic cancer cell lines (AsPC1, BxPC3, Capan1, Capan2, CFPAC1, HPAF II, MIAPaca2, Panc1, Panc03.27, PSN1, PL45, SW1990, Hs766T) to detect the mRNA level of FOXM1 and the IC50 for gemcitabine, and analyzed the correlation between the two. The gene discussed is NT5C3A; the disease is familial pancreatic carcinoma.
