RNA sequencing of bronchial epithelial cells cultured in air-liquid interface for 7 days treated or not with an antibody targeting the sonic hedgehog ligand (AB5E1)

The hedgehog pathway is crucial during airway epithelial cell differentiation. To assess the transcriptomic print of airway epithelial cells in absence of hedgehog pathway activation, we performed a comparative transcriptomic analysis on air-liquid interface cell cultures. Bronchial epithelial cells from 5 non-COPD subjects (ex- and current smokers) were isolated from bronchial brushes and cultured in air-liquid interface. The total RNA were extracted after 7 days of culture in air-liquid conditions in presence of an antibody targeting the sonic hedgehog ligand (AB5E1) or not (CTL). The libraries were prepared with NEBNext Ultra II directeional RNA Library Prep Kit and sequenced on Illumina.
