Molecular responses of Nile tilapia (Oreochromis niloticus) to different levels of dietary carbohydrates

Our study aimed at characterizing for the first time the molecular effects of increased dietary carbohydrates (dextrin) from 0% up to 50% in Nile tilapia during 45 and 90 days. Our study confirmed that Nile tilapia can use high level of carbohydrates without any deregulation of glucose homeostasis. However, no strong regulations of expression for genes involved in glucose metabolism in liver and muscle - which could explain the reasons for an efficient use of carbohydrate by this fish species - were detected.
