Assessment of RNA quality in airway epithelial samples. Integrity of 180 RNA samples was scored using the RNA Integrity Number (RIN) generated by Agilent 2100 Bioanalyzer Software (1 = highly degraded; 10 = intact). Samples are grouped by phenotype as defined in Methods, and within each phenotype the site of the epithelial sample is indicated (trachea; large airway; small airway). Samples with RIN ≥ 7.0, shown by the dotted line, passed QC criterion, while the 5 samples below the dotted line failed the QC criterion.
