Pre- and post-prandial changes of <i>copa</i> mRNA expression in the goldfish hypothalamus (A), J-loop (B), and liver (C).

<p>The mRNA expression of <i>copa</i> was normalized to <i>β-actin</i> and represented relative to the -3 h scheduled feeding group. Data are presented as mean + SEM (n = 4 fish). Columns sharing a same letter are not statistically different (p < 0.05, one-way ANOVA and Student-Newman-Keuls tests).
