Abstract
We determined GSK-3 expression and phosphorylation as well as the expression of negative regulators (Akt and SGK) and downstream activation of β-catenin in nasal polyps of patients with CRSwNP by immunohistochemistry and Western blot experiments. In this study we demonstrated for the first time, that 1,8-cineol acts as a potential inhibitor of the Wnt/β-catenin signaling pathway, by affecting the inhibitory phosphorylation of GSK-3, which is the key regulator of the β-catenin activity. Our data provide novel insights in the regulatory networks responsible for the progression of CRSwNP and furthermore represent a new mechanism of 1,8-cineol activity, which may lead to novel treatment approaches to this natural drug.
