Western blot analysis of mitochondrial proteins also revealed significantly reduced levels of PINK1, parkin, BNIP3, and FUNDC1 in the nasal polyps of patients with eCRSwNP (P < 0.001, 0.004, 0.002, and 0.013, respectively), compared with control tissues (Figures 4(e) and 4(f)). This evidence concerns the gene FUNDC1 and Nasal polyposis.
