Fig. 4.

Effects of exogenously administered phoenixin-20 (PNX-20) on food intake levels of male (left) and female (right) zebrafish (ZF). Shown are food intake levels at 1 h postintraperitoneal administration of saline alone (control) or containing 1 and 10 (A and B) or 100 and 1,000 (C and D) ng/g body wt of PNX-20. Data are presented as means ± SE (n = 6 fish/group). ★P < 0.05, significant differences between control and treated groups. One-way ANOVA followed by Tukey’s multiple-comparison test was used for statistical analysis.
