ARTICLE HIGHLIGHTS
Research background
Hirschsprung’s disease (HD)-associated enterocolitis (HAEC) is the most common and serious complication of HD. The intestinal structure of zebrafish is similar to that of humans. The zebrafish model can effectively fill the gap between in vitro and mammalian experiments, and improve the existing drug research and development process.
Research motivation
At present, the pathogenesis of HAEC is not clear. Therefore, clarifying the pathogenic mechanism or characteristic pathogenic pathway of HAEC and blocking the vicious cycle of the pathogenic pathway may be an effective way to prevent and treat HAEC.
Research objectives
This study aimed to explore the therapeutic effect and possible mechanism of action of glycyrrhizic acid (GA) on HAEC, and provide an important theoretical and experimental basis for the prevention and treatment of HAEC.
Research methods
In this study, fish fry at 3 d post-fertilization (dpf) were treated with trinitrobenzene sulfonic acid (TNBS), and 8 dpf enteritis model fish were obtained after 5 d of continuous treatment between 8 and 11 dpf, and changed daily for 3 d. To analyze the effect of GA on the phenotype and inflammatory status of zebrafish, zebrafish can be divided into normal phenotype and intestinal enlargement phenotype according to malformation.
Research results
In zebrafish, the intestinal luminal area of TNBS-treated zebrafish was increased compared with that of TNBS-untreated zebrafish. Although TNBS increased the number of goblet cells in the intestinal lumen and promoted intestinal inflammation, TNBS treatment did not decrease the survival rate of zebrafish. After GA treatment, the intestinal luminal area, number of goblet cells in the intestinal lumen, and levels of interleukin (IL)-1β and IL-8 were significantly changed.
Research conclusions
TNBS was used to construct a zebrafish enteritis model, and different concentrations of GA were used to treat enteritis. In the analysis of the effects of GA on the phenotype and inflammatory state of zebrafish, different concentrations of GA had protective effects on zebrafish with enteritis.
Research perspectives
The protective effect of GA on zebrafish enteritis was confirmed, but its specific mechanism still needs to be further explored.
