Role of epigenetics in the pathogenesis of chronic rhinosinusitis with nasal polyps.

ABSTRACT: Chronic rhinosinusitis (CRS) is a highly prevalent disease characterized by mucosal inflammation of the nose and paranasal sinuses. CRS can be divided into two main categories, CRS with nasal polyps (NPs; CRSwNP) and CRS without NPs (CRSsNP). Although the pathophysiology of CRS remains unclear, DNA methylation has been implicated in the etiology of CRSwNP. The aim of the present study was to elucidate whether DNA methylation of specific genes is involved in the development of NPs. In total, 18 individuals were included in the present study, and were divided into three groups: CRSwNP (n=7), CRSsNP (n=7) and healthy controls (n=4). NP tissues were obtained from the seven patients with CRSwNP and biopsies of the inferior turbinate mucosa from all three groups were used as controls. Methylated
