Title	THE PHARMACOLOGICAL RESCUE OF CFTR BY LUMACAFTOR (VX-809) IN THE CYSTIC FIBROSIS BRONCHIAL EPITHELIUM IS ASSOCIATED WITH AN EXTENSIVE REORGANIZATION OF MITOCHONDRIA.
Description	Cystic Fibrosis (CF) is a genetic disorder CF is caused by mutations of the gene encoding for the cystic fibrosis transmembrane conductance regulator protein (CFTR), a transmembrane anion channel expressed at the apical membrane of several organs, including the epithelial cells of the airway. CFTR mutations result in dysfunctional ion transport across the apical membrane at the surface of the epithelia, generating thickened and dehydrated secretions. In the lung, this leads to a decrease in the mucociliary clearance, favoring bacterial colonization and progressive obstruction of the duct. Although over 2000 CFTR variants have been identified so far, the most common mutation is a deletion of the phenylalanine in position 508 (F508del), which shows an allelic frequency of around 90% among CF patients. F508del-CFTR is incorrectly folded, causing its retention at the endoplasmic reticulum (ER) and subsequent proteasomal degradation. Among the several drugs available in CF pharmacological treatment, VX-809 (commercial name Lumacaftor) is the most used drug for patients carrying F508del-CFTR mutation. This drug corrects the aberrant folding of F508del-CFTR by favoring the correct intramolecular interactions, thus enabling a higher number of copies of the defective protein to reach the plasma membrane. We applied SWATH-based proteomics to understand if a pharmacological rescue of F508del-CFTR is associated with changes in global protein expression of the human bronchial epithelium by using the CFBE41o- cell model, a line that stably expresses F508del-CFTR.
