University Hospital, Montpellier
  Purpose
Epigenetic modifiers has been showed to rescue F508del-CFTR channel to apical membrane of epithelial cell lines. In this study, the investigators evaluate epigenetic modifiers effects firstly on CFTR rescue, then on secretion and synthesis of inflammatory factors (IL-8, LXA4 and SCGB1A1) and mucines (MUC5AC and MUC5B) in a dynamic epithelium model using an air-liquide interface culture of nasals cells from CF patients or controls.

Condition Intervention
Cystic Fibrosis Healthy Subjects Other: Tests in vitro after sampling nasal cells of CF patients or controls

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Action of Epigenetic Modifiers in Cystic Fibrosis Treatment: ex Vivo Model of Nasal Epithelium of CF Patients

Secondary Outcome Measures:
  • Pro-inflammatory cytokines number variations after epigenetic modifiers treatment [ Time Frame: 24 months ]

Enrollment: 39
Study Start Date: January 2012
Study Completion Date: November 2014
Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cystic Fibrosis patients (CF)
Tests in vitro after sampling nasal cells of CF patients or controls are the intervention done on these subjects
Other: Tests in vitro after sampling nasal cells of CF patients or controls
Nasal cells of CF patients or controls were collected by scratching of intermediate turbinate and cultured in vitro. Epigenetic modifiers treatment was applied to these ex vivo nasal epithelia. Then, mRNA, protein and secretions were quantified.
Control subjects (non CF)
Tests in vitro after sampling nasal cells of CF patients or controls are the intervention done on these subjects
Other: Tests in vitro after sampling nasal cells of CF patients or controls
Nasal cells of CF patients or controls were collected by scratching of intermediate turbinate and cultured in vitro. Epigenetic modifiers treatment was applied to these ex vivo nasal epithelia. Then, mRNA, protein and secretions were quantified.
