Figure 4. Expression of Drosophila insulin-like peptide in each cohort. Represented in abscises are time points (hours) after switch, in ordinates are shown the mRNA expression scores in the log2 scale. (A) Dilp5 is a category I gene, with expression down-regulated in RF cohort as compared to CF cohort. (B) Dilp6 is up-regulated in RF cohort as compared to CF cohort. However, dilp6 can't be clearly assigned to one of the main category due to its intermediate behaviors during time courses. (C) Dilp2 level doesn't change between three cohorts
