FUNDC1 and nasal cavity polyp: Western blot analysis of total proteins revealed reduced levels of PINK1, parkin, BNIP3, and FUNDC1 in the nasal polyps of patients with eCRSwNP (P = 0.002, <0.001, 0.001, and <0.001, respectively) or noeCRSwNP (P = 0.002, <0.001, <0.001, and <0.001, respectively), compared with control tissues (Figures 4(c) and 4(d)).
