The cystic fibrosis transmembrane conductance regulator (CFTR) protein is highly expressed in the pancreatic duct epithelia and permits anions and water to enter the ductal lumen. This results in an increased volume of alkaline fluid allowing the highly concentrated proteins secreted by the acinar cells to remain in a soluble state. This work will expound on the pathophysiology and pathology ca...

Liver changes observed in the course of cystic fibrosis comprise a group of complex processes of fibrosis, inflammation, remodelling, apoptosis and cholestasis as a result of abnormal functioning of the cystic fibrosis transmembrane conductance regulator (CFTR) protein, immunological reactions and response to oxidation stress. Liver lesions are only observed in 5-20% of patients with diagnosed ...

The median life expectancy for cystic fibrosis is now over 30 years, and it is projected that in newborn infants it will become more than 40 years. The identification of the cystic fibrosis gene and its product, cystic fibrosis transmembrane conductance regulator (CFTR), has widened the spectrum of the disease from the classical case of the infant with cystic fibrosis to the elderly childless m...

Cystic fibrosis (CF) is a disease caused by a mutation in the cystic fibrosis transmembrane conductance regulator protein in the epithelial membrane, and affects at least 30,000 people in the USA. There are between 900 and 1000 new cases diagnosed every year. Traditionally, CF has been treated symptomatically with pancreatic enzymes, bronchodilators, hypertonic saline, and pulmozyme. In July 20...

The cystic fibrosis transmembrane conductance regulator (CFTR) anion channel is essential to maintain fluid homeostasis in key organs. Functional impairment of CFTR due mutations the cftr gene leads fibrosis. Here, we show that first nucleotide-binding domain (NBD1) can spontaneously adopt an alternate conformation departs from canonical NBD fold previously observed. Crystallography reveals thi...

Experimental evidence of fluid secretion of rabbit lacrimal gland duct epithelium. A novel, protective role of ursodeoxycholate in bile-induced pancreatic ductal injury. levels and function of the cystic fibrosis transmembrane conductance regulator to promote development of pancreatitis.

INTRODUCTION Cystic fibrosis, an epithelial cell transport disorder caused by mutations of the cystic fibrosis transmembrane conductance regulator gene, is not generally associated with malformations of the central nervous system. We review eight previously published reports detailing an infrequent association between cystic fibrosis and Chiari I malformation. CASE PRESENTATION To the best of...

Interleukin (IL)-8 levels are higher than normal in cystic fibrosis (CF) airways, causing neutrophil infiltration and non-resolving inflammation. Overexpression of microRNAs that target IL-8 expression in airway epithelial cells may represent a therapeutic strategy for cystic fibrosis. IL-8 protein and mRNA were measured in cystic fibrosis and non-cystic fibrosis bronchoalveolar lavage fluid an...
