The results demonstrated that the mRNA of Galectin-1 in PSCs were significantly higher than that in pancreatic cancer cell lines (BxPC-3, SW1990,CFPAC-1 and PANC-1), and the mRNA of Galectin-1 in hCaPSC was also significantly higher than the hNPSC (Figure 3a), which were coincident with the results of immunohistochemistry (Figure 1). The gene discussed is LGALS1; the disease is familial pancreatic carcinoma.
