Abstract:
Objective The aim of this study is to explore the hypoglycemic effect of active components of Anoectochilus roxburghii on zebrafish models. Methods Anoectochilus roxburghii components were extracted and separated into three groups: the alcohol extraction group, macromolecular polysaccharide group (≥ 5 ×103) and small molecular polysaccharide group (＜5×103). Zebrafish embryos were exposed to 2% glucose solution (2% Glu) at 24 h to imitate acute hyperglycemia phenotype, and then treated with the three Anoectochilus roxburghii components. Based on this high-glucose model, the zebrafish embryos at 72 h were collected to detect the whole tissue glucose value. Furthermore, semi-quantitative PCR and whole mount in situ hybridization were performed to detect the expression of mRNA levels of glycometabolism-related genes. Results An acute diabetic zebrafish model was induced by high glucose stress. In this model, some key factors during glycometabolism such as insulin, pck-1 and pdx-1 were significantly affected, while the alcohol extracts of Anoectochilus roxburghii obviously reversed these abnormalities induced by high glucose stress, even to normal levels. Conclusions The alcohol extracts of Anoectochilus roxburghii has obvious hypoglycemic effect on diabetic zebrafish model. Our result suggest that Anoectochilus roxburghii has a potential application in the hypoglycemic drug screening.
