Fig 4. Expression differences of anorexigenic genes in the gut of wild-type versus lepr mutant zebrafish in each feeding group. Means and standard errors of fold changes in expression of five biological replicates are shown for each experimental group. Significant differences between the lepr mutant and wild-type are delineated by asterisks ( � P < 0.05; �� P < 0.01; ��� P <
