Functional Rescue of F508del-CFTR Using Small Molecule Correctors
High-throughput screens for small molecules that are effective in "correcting" the functional expression of F508del-CFTR have yielded several promising hits. Two such compounds are currently in clinical trial. Despite this success, it is clear that further advances will be required in order to restore 50% or greater of wild-type CFTR function to the airways of patients harboring the F508del-CFT...
متن کاملTezacaftor/Ivacaftor in Subjects with Cystic Fibrosis and F508del/F508del-CFTR or F508del/G551D-CFTR.
RATIONALE Tezacaftor (formerly VX-661) is an investigational small molecule that improves processing and trafficking of the cystic fibrosis transmembrane conductance regulator (CFTR) in vitro, and improves CFTR function alone and in combination with ivacaftor. OBJECTIVES To evaluate the safety and efficacy of tezacaftor monotherapy and of tezacaftor/ivacaftor combination therapy in subjects w...
متن کاملPharmacological Correctors of Mutant CFTR Mistrafficking
The lack of phenylalanine 508 (ΔF508 mutation) in the cystic fibrosis (CF) transmembrane conductance regulator (CFTR) Cl(-) channel represents the most frequent cause of CF, a genetic disease affecting multiple organs such as lung, pancreas, and liver. ΔF508 causes instability and misfolding of CFTR protein leading to early degradation in the endoplasmic reticulum and accelerated removal from t...
متن کاملA chemical corrector modifies the channel function of F508del-CFTR.
The deletion of Phe-508 (F508del) constitutes the most prevalent cystic fibrosis-causing mutation. This mutation leads to cystic fibrosis transmembrane conductance regulator (CFTR) misfolding and retention in the endoplasmic reticulum and altered channel activity in mammalian cells. This folding defect can however be partially overcome by growing cells expressing this mutant protein at low (27 ...
متن کاملCorrectors promote folding of the CFTR in the endoplasmic reticulum.
Cystic fibrosis (CF) is most commonly caused by deletion of a residue (DeltaF508) in the CFTR (cystic fibrosis transmembrane conductance regulator) protein. The misfolded mutant protein is retained in the ER (endoplasmic reticulum) and is not trafficked to the cell surface (misprocessed mutant). Corrector molecules such as corr-2b or corr-4a are small molecules that increase the amount of funct...
