title: Dysregulation of E-cadherin in chronic rhinosinusitis with nasal polyps.
abstract: E-cadherin is a key epithelial protein and adhesive molecule. This study detected the E-cadherin expression in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and controls, and analyzed its possible role in the pathogenesis of CRSwNP. The expression of E-cadherin was detected by using Western blotting and immunohistochemistry in controls and patients with CRSwNP. Computed tomography (CT) scan findings were scored. The results showed that the E-cadherin expression was up-regulated in patients with CRSwNP as compared with controls (P=0.039) and the positive staining was predominantly localized on the epithelial cell membrane. E-cadherin level was correlated negatively with Lund-Mackay scores in patients with CRSwNP (r=-0.604, P=0.005). It is suggested that E-cadherin may be involved in the pathogenesis of CRSwNP and correlated with disease severity.
