BACKGROUND: Periodontitis is a common complication of diabetes, with advanced glycation end products (AGEs) playing a key role in its pathogenesis. Albiflorin, a monoterpene glycoside, has shown potential anti-inflammatory and antioxidant properties. This study aims to investigate the effects of albiflorin on AGEs-induced gingival fibroblasts and its underlying mechanisms.
OBJECTIVE: This study aimed to evaluate the role of albiflorin in mitigating ROS production, inflammation, and MMP-1 expression in AGEs-induced gingival fibroblasts.
METHODS: The viability of gingival fibroblasts treated with albiflorin and AGEs was assessed using CCK-8 assays. ROS levels were measured by DCF staining, and the expression of inflammatory markers and MMP-1 was evaluated by ELISA and qPCR. The involvement of the NF-κB and Nrf2 pathways was examined by immunoblotting.
RESULTS: Albiflorin enhanced the viability of AGEs-induced gingival fibroblasts and reduced ROS production. It also decreased the expression of IL-6, IL-8, RAGE, and MMP-1, suggesting an anti- inflammatory effect. Mechanistically, albiflorin modulated the NF-κB and Nrf2 pathways in AGEs-induced gingival fibroblasts.
CONCLUSION: Albiflorin exhibited protective effects against AGEs-induced oxidative stress and inflammation in gingival fibroblasts, highlighting its potential as a therapeutic agent for periodontitis in diabetic patients. The modulation of the NF-κB and Nrf2 pathways by albiflorin provides insight into its mechanism of action.
