Popis: | Objective. To investigate the protective effect and molecular mechanism of nuclear factor E2-related factor 2 (Nrf2) pathway in interstitial cystitis (IC). Methods. We established a mouse model of IC by cyclophosphamide (CYP) in wild-type mice and Nrf2 gene knockout mice. We examined the histological and functional alterations, the changes of oxidative stress markers, and the expression of the antioxidant genes downstream of Nrf2 pathway. Results. After CYP administration, the mice showed urinary frequency and urgency, pain sensitization, decreased contractility, bladder edema, and oxidative stress disorder. Notably, the Nrf2-/- CYP mice had more severe symptoms. The mRNA and protein levels of antioxidant genes downstream of Nrf2 pathway were significantly upregulated in the Nrf2+/+ CYP mice, while there were no significant changes in the Nrf2-/- CYP mice. Conclusion. Nrf2 pathway protects bladder injury and ameliorates bladder dysfunction in IC, possibly by upregulating antioxidant genes and inhibiting oxidative stress. |
