DIO results in increased body weight, length and BMI in both male and female zebrafish. (A), (B) Graphs illustrating the body weight measurements during 4 weeks for both CTRL and DIO-treated zebrafish in male and female, respectively. The zebrafish pictures highlight the morphological differences at week 4. (C), (D) Body length measurements at week 4 in male and female zebrafish, respectively. (E), (F) Body mass index (BMI; grams per square centimeter) calculated at week 4. n = number of fish. One-way ANOVA (A, B) and Student's t-test (C–F): **p < 0.01; ****p < 0.0001. Error bars correspond to standard error of the mean (SEM). Scale bar: 7 mm.
