We found that Galectin-1 mRNA and protein levels were significantly higher in isolated cultured PSCs compared to pancreatic cancer cell lines (BxPC-3, CFPAC-1, SWl990 and PANC-1), which is consistent with the immunohistochemisty results that Galectin-1 mostly expressed in cancer-associated stromal cells. The gene discussed is LGALS1; the disease is familial pancreatic carcinoma.
