Current research topics

In the context of the replacement of fish meal by inclusion of alternative terrestrial plant products in aquafeed formula, digestible carbohydrates represent good candidates. However, when fish meal is substituted at more than 20% by digestible carbohydrates, rainbow trout (Oncorhynchus mykiss) displays a persistent postprandial hyperglycemia defining it as a glucose-intolerant species. Indeed, rainbow trout belongs to a high trophic level and is thus considered as a strict carnivorous species metabolically adapted for high catabolism of proteins (> 37%) and low utilization of dietary carbohydrates. Hepatic gluconeogenesis in trout, the metabolic pathway producing endogenous glucose to sustain vital function from mainly amino acids, is poorly, if ever, regulated by carbohydrates, suggesting that this metabolic pathway is involved in the establishment of the glucose-intolerant phenotype. In the context of pathologies affecting the glucose homeostasis like diabetes, epigenetic changes occur at the overall genome level, but also at the gluconeogenic genes loci level associated with an increase in their expression and an endogenous glucose production in the liver.
In this context, my main working hypothesis is that changes in the hepatic epigenetic landscape induced by dietary carbohydrates at the global level and at the gluconeogenic genes loci may be involved in the maintenance of endogenous glucose production in rainbow trout fed a high carbohydrate diet. To explore this hypothesis, I particularly pay attention to explore the whole complexity of the rainbow trout genome. Indeed, an additional whole genome duplication event occurred at the base of the radiation of the salmonid fish, resulting in duplicated copies of many single-copy human genes. These duplicated genes are, in principle, available for the evolution of new functions that could drive the origin of novelties and thus contribute to the diversification of life on Earth. They are thus all highly important to consider to better understand original phenotypes such as the glucose-intolerant phenotype in trout.
My work thus revolves around three objectives: 1) understand the role of duplicated gluconeogenic genes in the establishment of the glucose-intolerance phenotype and their regulation by dietary carbohydrates, 2) study the global epigenetic changes induced by dietary carbohydrates and their underlying mechanisms, and 3) study the nutritional programming as a strategy to improve the use of dietary carbohydrates via the modulation of the global epigenome and the gluconeogenesis pathway.
