Sulfate transport in normal and cystic fibrosis fibroblasts.


The glycoconjugate component of cystic fibrosis (CF) epithelial secretions is abnormally sulfated. Previous studies have suggested that some but not all CF fibroblasts express this secondary defect. We tested the hypothesis that the major CF mutation (delta F508/delta F508) is correlated with elevated sulfate transport, by measuring the rates of saturable… (More)
