FIGURE 5.
Effects of the glucose injection history and dietary carbohydrate challenge on the global DNA methylation in Nile tilapia. The levels of 5-methylcytosine (5-mC%: 5-mC/total DNA) in the DNA in the liver (A) and muscles (B) were measured in fish challenged with different dietary carbohydrate levels (37% carbohydrates, CHO-M; 67% carbohydrates, CHO-H). Data are presented as the mean ± SD (n = 6). Two-way ANOVA was used to analyze the effects of glucose injection (History), challenging diet (Diet) and their interaction (History × Diet).
