Pancreatic adenocarcinoma cell lines rarely express the CFTR gene, despite the high levels of CFTR protein that are present in primary pancreatic duct cells. We have attempted to generate a non-CF pancreatic adenocarcinoma cell line that stably produces high levels of CFTR mRNA and protein by transfecting a vector containing the CFTR cDNA, driven by a strong mammalian promoter, into the poorly differentiated pancreatic adenocarcinoma cell line, Panc-1. The pANS6 pancreatic duct cell line expresses substantial levels of CFTR mRNA, but little CFTR protein. Despite this we were able to detect low conductance chloride channels in 40% of patches, stimulated with cAMP, that have similar biophysical properties to CFTR.
