Global gene expression in muscle from fasted/refed trout reveals up-regulation of genes promoting myofibre hypertrophy but not myofibre production. Oncorhynchus mykiss

To learn more about the contribution of genes regulating hypertrophy (increase in muscle fibre size) and hyperplasia (generation of new muscle fibres) in the compensatory muscle growth response in fish, we used high-density trout microarray to investigate the global gene expression in trout muscle during a fasting-refeeding schedule and in control-fed trout displaying normal growth. Overall design: global gene expression in trout muscle during a fasting-refeeding schedule and in control-fed trout displaying normal growth

为探究调控肌肉肥大（肌纤维尺寸增大）与增生（新生肌纤维生成）的基因在鱼类代偿性肌肉生长反应中的贡献，本研究使用高密度鳟鱼微阵列（microarray）技术，对处于禁食-复饲周期的鳟鱼肌肉，以及正常喂食且生长正常的对照鳟鱼的全基因组基因表达谱进行了分析。实验整体设计：检测处于禁食-复饲周期的鳟鱼肌肉，以及正常喂食且生长正常的对照鳟鱼的全基因组基因表达情况。
