No expression of sst1 was observed in any of the five pancreatic cancer cell lines (Panc-1, BxPC-3, Capan-1, MIA PaCa-2, CFPAC-1), or in pancreatic cancer cells from forty-two human PDACs, as assessed by Western blot or immunofluorescence analyses, respectively, using an anti-sst1 antibody, the specificity of which had been validated here. This evidence concerns the gene SST and pancreatic neoplasm.
