Abstract Cystic fibrosis (CF) is a genetic disorder that causes severe damage to the lungs and digestive system. CF affects cells produce mucus, sweat, enzymes caused by mutations in Fibrosis Transmembrane Conductance Regulator (CFTR). Expression function of CFTR have been extensively studied on epithelial several recent publications shown also regulates functions myeloid cells. We addressed wh...
One of the major therapeutic strategy in cystic fibrosis aims at developing modulators of cystic fibrosis transmembrane conductance regulator (CFTR) channels. We recently discovered methylglyoxal alpha-aminoazaheterocycle adducts, as a new family of CFTR inhibitors. In a structure-activity relationship study, we have now identified GPact-11a, a compound able not to inhibit but to activate CFTR....
The identification of the cystic fibrosis transmembrane conductance regulator gene (CFTR) in 1989 represents a landmark accomplishment in human genetics. Since that time, there have been numerous advances in elucidating the function of the encoded protein and the physiological basis of cystic fibrosis. However, numerous areas of cystic fibrosis biology require additional investigation, some of ...
The cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP-regulated chloride channel in the plasma membrane of several epithelial cells. Maturation of CFTR is inefficient in most cells, with only a fraction of nascent chains being properly folded and transported to the cell surface. The most common mutation in CFTR, CFTR-deltaF508, leads to the genetic disease cystic fibrosis. CF...
The cystic fibrosis transmembrane conductance regulator (CFTR), a chloride channel with 12 membrane-spanning sequences, undergoes inefficient maturation in the endoplasmic reticulum (ER). Potentially charged residues in transmembrane segments may contribute to this defect in biogenesis. We demonstrate that transmembrane segment 6 of CFTR, which contains three basic amino acids, is extremely uns...
Available commercial kits only screen for the most common cystic fibrosis transmembrane conductance regulator (CFTR) mutations causing classic cystic fibrosis and for the Tn variant in IVS8. However, full scanning of CFTR is needed for the diagnosis of patients with cystic fibrosis or CFTR-related disorders (including congenital bilateral absence of the vas deferens) bearing rare mutations. Sta...
In cystic fibrosis (CF), the most frequent mutant variant of the cystic fibrosis transmembrane conductance regulator (CFTR), F508del-CFTR protein, is misfolded and retained in the endoplasmic reticulum (ER). We previously showed that the unfolded protein response (UPR) may be triggered in CF. Since prolonged UPR activation leads to apoptosis via the calcium-calpain-caspase-12-caspase-3 cascade ...
Secretory diarrhea is the leading cause of infant death in developing countries and a major cause of morbidity in adults. The cystic fibrosis transmembrane conductance regulator (CFTR) protein is required for fluid secretion in the intestine and airways and, when defective, causes the lethal genetic disease cystic fibrosis. We screened 50,000 chemically diverse compounds for inhibition of cAMP/...
Recent research has demonstrated that transport of excess fluoride in cystic fibrosis (CF) occurs in the mutated transmembrane conductance channel regulator (CFTR). Since disturbances in these channels are responsible for the symptoms associated with CF, this knowledge that fluoride is also transported through these channels opens ways to achieve a better understanding of how fluoride exacerbat...
UNLABELLED In order to increase knowledge of the pathogenic effect of the 5T-12TG allele of the cystic fibrosis transmembrane conductance regulator (CFTR) gene, we evaluated its presence in 24 hypertrypsinaemic newborns with borderline sweat tests. Among 20 CFTR-identified alterations, the 5T-12TG haplotype was the second most frequent mutation (14.6%) over F508del. CONCLUSION Our study sugge...
