An element in intron 1 of the CFTR gene augments intestinal expression in vivo.


The elements controlling the complex developmental and tissue-specific expression of the cystic fibrosis transmembrane conductance regulator (CFTR) gene lie outside the basal promoter region and have not been characterized. We previously identified a tissue-specific DNase I hypersensitive site (DHS) in intron 1 (185 + 10 kb) of the CFTR gene. Here we show… (More)
