Expressional analysis of medaka genes by real-time RT PCR. (A): male; (B): female. Data are represented as the mean ± standard deviation (SD), (n = 4); * indicates significant difference (p < 0.05), ** indicates significant difference (p < 0.01). fasn: fatty acid synthase, srebf1: sterol regulatory element binding transcription factor 1, acc1: phospho-acetyl CoA Carboxylase 1, ppar-gamma: Peroxisome Proliferator-Activated Receptor γ, ppar-alpha: peroxisome proliferator-activated receptor α, g6pase: glucose-6-phosphatase, glut2: glucose transporter 2, pepck2: phosphoenolpyruvate carboxykinase2, acox: acyl-CoA oxidase, cpt1: carnitine palmitoyltransferase 1, lpl: lipoprotein lipase, hsl: hormone sensitive lipase, pnpla2: phospholipase domain-containing protein 2, hacl1: 2-hydroxyacyl-CoA lyase 1.
