The aim of this hypothesis is to provide new insights into the still unclear mechanisms governing airway inflammation in cystic fibrosis. Although the genetic basis of cystic fibrosis as well as the molecular structure of cystic fibrosis transmembrane regulator (CFTR), the mutated protein which causes the disease, have been well defined, a clear relationship between the genetic defect and the p...

Cystic fibrosis is an autosomal recessive disease caused by a wide spectrum of mutations in the gene encoding for the cystic fibrosis transmembrane conductance regulator protein. These mutations that correlate with different phenotypes, vary in their frequency and distribution in different populations. In this study missense mutation R117H that associated with the different clinical symptoms wa...

OBJECTIVE Longer survival of patients with cystic fibrosis has increased the occurrence of cystic fibrosis-related diabetes (CFRD). In this study we documented the incidence of CFRD and evaluated the association between mutations responsible for cystic fibrosis and incident CFRD, while identifying potential risk factors. RESEARCH DESIGN AND METHODS This was a population-based longitudinal stu...

The cystic fibrosis transmembrane conductance regulator (CFTR) Cl- channel belongs to the ATP-binding cassette (ABC) transporter superfamily and regulates Cl- secretion in epithelial cells for water secretion. Loss-of-function mutations to the CFTR gene cause dehydrated mucus on the apical side of epithelial cells and increase the susceptibility of bacterial infection, especially in the airway ...

BACKGROUND Cystic fibrosis (CF) is an autosomal recessive disease that is predominantly seen in the Caucasian population and involves multiple organs. Traditionally it has been thought that the kidney is the only organ which does not seem to be generally affected by the disease although the cystic fibrosis transmembrane conductance regulator (CFTR) gene is expressed in the kidney. CASE PRESEN...

Mutations in cystic fibrosis transmembrane regulator (CFTR), a chloride channel in the apical membranes of secretory epithelial cells, underlie the fatal genetic disorder cystic fibrosis. Certain CFTR mutations, including the common mutation ΔF508-CFTR, result in greatly decreased levels of active CFTR at the apical membrane. Direct interactions between CFTR and the cytoskeletal adaptors filami...

Cystic Fibrosis (CF) is the most common lethal monogenic disorder in Caucasians, estimated to affect one per 2500-4000 newborns. CF is caused by mutations in the gene encoding the CF transmembrane conductance regulator (CFTR) [1, 2]. CFTR acts mainly as a chloride channel and has other regulatory roles, including inhibition of sodium transport through the epithelial sodium channel, regulation o...

introduction: the cystic fibrosis transmembrane conductance regulator (cftr) chloride (cl−) channel is an essential component of epithelial cl− transport systems in many organs. cftr is mainly expressed in the lung and other tissues, such as testis, duodenum, trachea and kidney. the ubiquitin ligase neural precursor cells expressed developmentally down-regulated protein 4-2 (nedd4-2) has previo...

Cystic fibrosis is a fatal genetic disease, most frequently caused by the retention of the CFTR (cystic fibrosis transmembrane conductance regulator) mutant protein in the endoplasmic reticulum (ER). The binding of the 14-3-3 protein to the CFTR regulatory (R) domain has been found to enhance CFTR trafficking to the plasma membrane. To define the mechanism of action of this protein-protein inte...
