F508del-CFTR
(Fisher rat thyroid cells) 0.1 μM(EC50)
|
| In vitro |
Lumacaftor (VX-809) acts at the level of the ER to allow a fraction of the F508del-CFTR to adopt a properly folded form, to exit the ER and mobilize to the cell surface for normal functioning. In Fischer rat thyroid (FRT) cells expressing F508del-CFTR, this compound treatment significantly improves F508del-CFTR maturation by 7.1 fold with an EC50 of 0.1 μM, and enhances F508del-CFTR-mediated chloride transport by approximately 5 fold with EC50 of 0.5 μM, while VRT-768 has higher EC50 values of 7.9 μM and 16 μM, respectively. In HEK-293 cells expressing F508del-CFTR, it (3 μM) increases F508del-CFTR exit from the ER by 6 fold, reaching levels comparable to 34% of CFTR. In primary human bronchial epithelial (HBE) cells with F508del-CFTR mutation, the agent increases CFTR maturation and enhances chloride secretion with EC50 of 350 nM and 81 nM, respectively, more efficacious than Corr-4a and VRT-325. F508del-CFTR corrected by it exhibits single-channel open probability of 0.39 similar to normal CFTR of 0.40. Unlike VX-770, it is not a CFTR potentiator, as acute addition has no effect on F508del-CFTR function. In contrast to VRT-325 and Corr-4a, it does not improve the processing of the normal or mutant forms of hERG or P-gp, as well as other disease-causing mislocalized proteins, including α1-antitrypsin Z mutant (E342K-α1-AT) or N370S-β-glucosidase, suggesting that it is specific for CFTR. It in combination with VRT-325 or Corr-4a has additive effect on CFTR-mediated chloride transport in cultured F508del-HBE. |

Les cellules FRT exprimant de manière stable le F508del-CFTR sont traitées avec des concentrations croissantes de Lumacaftor (VX-809) pendant 48 heures. Après incubation, les cellules sont récoltées dans une solution D-PBS glacée (sans calcium ni magnésium) et centrifugées à 1 000 × g à 4 °C. Les culots cellulaires sont lysés dans 1 % de Nonidet P-40, 0,5 % de désoxycholate de sodium, 200 mM de NaCl, 10 mM de Tris, pH 7,8, et 1 mM d'EDTA plus un mélange d'inhibiteurs de protéase (1:250) pendant 30 minutes sur glace. Les lysats sont centrifugés pendant 10 minutes à 10 000 × g à 4 °C pour culotter les noyaux et les matériaux insolubles. Environ 12 μg de protéines totales sont chauffées dans un tampon de Laemmli avec 5 % de β-mercaptoéthanol à 37 °C pendant 5 minutes et chargées sur un gel Tris-acétate de 3 % à 8 %. Le gel est transféré sur nitrocellulose et traité pour Western blotting en utilisant un anticorps monoclonal CFTR ou polyclonal anti-GAPDH. Les blots sont développés par chimiluminescence améliorée. La quantification des quantités relatives des bandes C et GAPDH est effectuée en utilisant l'analyse NIH ImageJ des films scannés.
