Extent of rescue of F508del-CFTR function by VX-809 and VX-770 in human nasal epithelial cells correlates with SNP rs7512462 in SLC26A9 gene in F508del/F508del Cystic Fibrosis patients

Restoration of R117H CFTR folding and function in human airway cells through combination treatment with VX-809 and VX-770.
Cystic fibrosis (CF) is a lethal recessive genetic disease caused primarily by the F508del mutation in the CF transmembrane conductance regulator (CFTR). The potentiator VX-770 was the first CFTR modulator approved by the FDA for treatment of CF patients with the gating mutation G551D. Orkambi is a drug containing VX-770 and corrector VX809 and is approved for treatment of CF patients homozygou...
متن کاملPseudomonas aeruginosa Reduces VX-809 Stimulated F508del-CFTR Chloride Secretion by Airway Epithelial Cells
BACKGROUND P. aeruginosa is an opportunistic pathogen that chronically infects the lungs of 85% of adult patients with Cystic Fibrosis (CF). Previously, we demonstrated that P. aeruginosa reduced wt-CFTR Cl secretion by airway epithelial cells. Recently, a new investigational drug VX-809 has been shown to increase F508del-CFTR Cl secretion in human bronchial epithelial (HBE) cells, and, in comb...
متن کاملEffect of VX-770 in persons with cystic fibrosis and the G551D-CFTR mutation.
BACKGROUND A new approach in the treatment of cystic fibrosis involves improving the function of mutant cystic fibrosis transmembrane conductance regulator (CFTR). VX-770, a CFTR potentiator, has been shown to increase the activity of wild-type and defective cell-surface CFTR in vitro. METHODS We randomly assigned 39 adults with cystic fibrosis and at least one G551D-CFTR allele to receive or...
متن کاملCorrection of the F508del-CFTR protein processing defect in vitro by the investigational drug VX-809.
Cystic fibrosis (CF) is caused by mutations in the CF transmembrane conductance regulator (CFTR) gene that impair the function of CFTR, an epithelial chloride channel required for proper function of the lung, pancreas, and other organs. Most patients with CF carry the F508del CFTR mutation, which causes defective CFTR protein folding and processing in the endoplasmic reticulum, resulting in min...
متن کاملEffect of VX-770 (ivacaftor) and OAG on Ca2+ influx and CFTR activity in G551D and F508del-CFTR expressing cells.
BACKGROUND TRPC6 has been proposed to be responsible for the abnormal OAG-dependent Ca(2+) influx in cystic fibrosis (CF) cells and we hypothesized that it interacts with CFTR. Here, we investigated how this functional complex operates in CF and non-CF epithelial cells. METHODS Chinese hamster ovary (CHO) cells stably transfected with pNut vector containing wild type CFTR (CHO-WT), F508del-CF...
