PPARγ gene expression was significantly lower in the airways of non-CF bronchiectasis subjects compared with healthy controls (control: 1.00, IQR 0.55–1.44, n = 20 vs. Bronchiectasis: 0.49, IQR 0.12–0.89; n = 35; p<0.001, Mann-Whitney U test), Fig 1. The gene discussed is PPARG; the disease is bronchiectasis.
