Resveratrol ameliorates necrotizing enterocolitis in neonatal rats through regulation of inflammatory and apoptotic pathways
Abstract
Purpose: To determine the efficacy of resveratrol in mitigating necrotizing enterocolitis (NEC) in neonatal rats.
Methods: Necrotizing enterocolitis (NEC) was induced in neonatal rats using hypoxia and hypothermia. At the completion of treatment, the intestinal tissues of the rats were isolated for evaluation of various biochemical parameters.
Results: There was significant increase in the levels of proinflammatory cytokines (TNF-α, IL-6 and IL-1β) and oxidative stress markers (MDA, xanthine oxidase and nitric oxide) in intestinal tissues of NEC rats (p < 0.05). However, resveratrol treatment led to significant decrease in the levels of cytokines and oxidative stress parameters, relative to the NEC group (p < 0.05). Furthermore, Western blotting results
showed up-regulation in protein expressions of inflammatory cytokines in NEC rats. However, the protein expressions of inflammatory cytokines were down-regulated in the NEC rats on treatment with resveratrol. Moreover, resveratrol reversed the NEC-induced up-regulations of Bax and caspase-3, as well as NEC-mediated down-regulation of Bcl-2.
Conclusion: These results demonstrate that resveratrol mitigates NEC-induced intestinal damage in neonatal rats via anti-inflammatory, anti-apoptotic and antioxidant mechanisms of action. Therefore, resveratrol is a potential therapeutic agent for NEC.
