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. |

F508del-CFTR rijping

FRT-cellen die stabiel F508del-CFTR tot expressie brengen, worden gedurende 48 uur behandeld met toenemende concentraties VX-809 (Lumacaftor). Na incubatie worden de cellen geoogst in ijskoude D-PBS-oplossing (zonder calcium en magnesium) en gepelleteerd bij 1.000 × g op 4 °C. Celpellets worden gedurende 30 minuten op ijs gelyseerd in 1% Nonidet P-40, 0,5% natriumdeoxycholaat, 200 mM NaCl, 10 mM Tris, pH 7,8 en 1 mM EDTA plus protease-inhibitiemengsel (1:250). Lysaten worden gedurende 10 minuten gecentrifugeerd bij 10.000 × g op 4 °C om kernen en onoplosbaar materiaal te pelletiseren. Ongeveer 12 μg totaal eiwit wordt gedurende 5 minuten op 37 °C verwarmd in Laemmli-buffer met 5% β-mercapto-ethanol en geladen op een 3% tot 8% Tris-acetaatgel. De gel wordt overgebracht op nitrocellulose en verwerkt voor Western blotting met behulp van een monoklonaal CFTR-antilichaam of een polyklonaal antilichaam tegen GAPDH. Blots worden ontwikkeld door middel van verbeterde chemiluminescentie. Kwantificering van de relatieve hoeveelheden van banden C en GAPDH wordt uitgevoerd met behulp van NIH ImageJ-analyse van gescande films.
