In addition, a recent study reported that ADCYAP1, BPIFA1, and PRDX2 were differentially expressed in the nasal mucosa of Caucasian patients with CRSwNP [69], confirming that the differential expression of these genes reduced the antioxidant capacity in patients with CRSwNP. Here, ADCYAP1 is linked to chronic rhinosinusitis with nasal polyps.
