Effect of different feeding regimes on pancreatic exocrine cell gene expression. a and (b) are bright field images of 15-day larvae that are representative for the fed or starved conditions. Larvae are viewed from lateral right side, mouth up. Stomach diameter was measured from ventral to dorsal, along the midline of the larval body. c Quantitative PCR analysis of SpPtf1a and digestive enzymes transcripts in feeding and fasting conditions. Data were normalized using ubiquitin as reference gene. Three biological replicas and three technical replicas were measured. The differences between groups that resulted significant by Student’s two tailed t-test are indicated as ** if p < 0.01 (highly significant)
