LCN2 and pancreatic neoplasm: Western blot revealed a high level of expression of the 24 kDa NGAL protein in all the well-differentiated pancreatic cancer cell lines (S2CP9, Colo357, HPAF, and HPAC), weak expression in the moderately differentiated pancreatic cancer cell lines (Capan-1, SW1990, HS766T, ASPC-1, and Panc89), and no detectable expression in the poorly differentiated pancreatic cancer cell lines (Panc1, MiaPaCa, BxPC3, and HCG25) (Figure 3).
