Interaction of intestinal and pancreatic transcription factors in the regulation of CFTR gene expression.
The tissue-specific regulation of the cystic fibrosis transmembrane conductance regulator gene (CFTR) is coordinated by intronic and extragenic cis-acting elements that influence its transcriptional activity. The promoter apparently lacks sequences to drive cell type-specific expression. We previously identified a number of intronic elements that were associated with DNase I hypersensitive sites (DHS) and bound the hepatocyte nuclear factor 1 (HNF1) transcription factor. Moreover, we demonstr...Expand abstract
