ABSTRACT
BACKGROUND:
Ulcerative colitis (UC) is a relapsing and chronic inflammatory disease of the gastrointestinal tract, which seriously threatens human health. Zingerone (ZO) has been proven to be effective for many diseases. The purpose of this study is to investigate the protective effects and potential mechanisms of ZO extracted from ginger on dextran sulfate sodium (DSS)-induced mouse ulcerative colitis (UC).RESULTS:
The results showed that ZO alleviated the weight loss of UC model mice, reduced the disease activity index scores, and inhibited the shortening of colon length. ZO also improved DSS-induced pathological changes in colon tissue and inhibited the secretion of pro-inflammatory cytokines in colon and mesenteric lymph nodes. Further mechanism analysis found that ZO inhibited DSS-induced nuclear factor-κB pathway activation, and regulated peroxisome proliferator-activated receptor γ (PPARγ) expression. To further explore whether PPARγ was involved in the anti-UC effect of ZO, PPARγ inhibitor GW9662 was used. Although ZO also showed a protective effect on GW9662-treated colitis mice, the protective role was significantly weakened. Importantly, the administration of GW9662 significantly aggravated UC compared with the ZO + DSS group. In addition, we preliminarily found that ZO had the effects of inhibiting DSS-induced oxidative stress, maintaining intestinal barrier, and inhibiting the content of LPS and the population of Escherichia coli.CONCLUSIONS:
These results indicated that supplementation with ZO might be a new dietary strategy for the treatment of UC. © 2022 Society of Chemical Industry.Palavras-chave
