Figure 4: 5f restored neural tube development and marker expression in chick embryos on EDD 5.

Glucose concentration (A) and Pax3 protein expression (B) were determined in chick embryos. The plasma glucose concentration was measured using a glucose oxidase-coupled spectrophotometric assay kit. Proteins were detected using the monoclonal antibody anti-Pax3 diluted 1:1000 (DSHB, USA) and visualized using anti-mouse IgG conjugated with horseradish peroxidase (HRP) and Pierce ECL Western Blotting Substrate (Thermo Fisher Scientific, USA) as the substrate of HRP. The abbreviations “CON”, “GLU”, “CL”, “CM”, “CH”, “EPA”, “EDA” mean “controlled”, “glucose treated”, “low concentration of 5f treated”, “mild concentration of 5f treated”, “high concentration of 5f treated”, “epalrestat treated”, “edaravone treated” groups, respectively. Values were expressed as mean ± SD in each group (n = 10). *P < 0.05, **P < 0.01 vs. control. #P < 0.05, ##P < 0.01 vs. glucose.
