Abstract | The Cftr (Cystic Fibrosis Transmembrane Conductance Regulator) gene codes for an epithelial chloride (C1) channel essential for fluid secretion into the respiratory and gastrointestinal tract and from exocrine glands. Mice lacking CFTR function due to a disruption of Cftr exon 10 or exon 1 (Cftr(mlUNC/MlUNC) or Cftr(mlHSC/mlHSC) mice, respectively) generally suffer from severe gastrointestinal disease resulting in death shortly after birth or at the time of weaning. However, a subgroup of the Cftr(mlHSC/mlHSC) mice have been characterized which exhibit relatively mild intestinal pathology resulting in a noncompromised lifespan compared to the more severely affected Cftr(mlUNC/mlUNC) mice. We compared the ion transport capacity of the intestinal mucosa of the mildly and severely affected CF mice using the in vivo technique of rectal potential difference (PD) measurement and found that the net calcium-activated chloride conductance toward the lumen was much greater in the rectum of mildly affected mice than in the severely affected mice. Hence, the milder phenotype may be related to the expression of a factor which enhances the net calcium-activated chloride conductance into the lumen of the intestinal tract. |
