Modulation of energy metabolism and epigenetic landscape in rainbow trout fry by a parental low protein/high carbohydrate diet

Project description:In rainbow trout (Oncorhynchus mykiss), the effect of a paternal and a maternal high carbohydrate/low protein diet was assessed on progeny. To this purpose, two-year old males and females rainbow trout were fed either a control diet or a high carbohydrate/low protein diet for an entire reproductive cycle for females and for 5 months for males. Crossed-fertilizations were carried out in order to obtain 4 groups of offspring. Before the first feeding, whole fry transcriptomes were compared to detect any impact of the parental diet on offspring metabolism.

No adverse effect of a parental low protein/high carbohydrate diet on their offspring, in rainbow trout (liver)

Project description:In rainbow trout (Oncorhynchus mykiss), the effect of a paternal and a maternal "high carbohydrate/low protein" diet was assessed on progeny. To this purpose, two-year old males and females rainbow trout were fed either a control diet or a "high carbohydrate/low protein" diet for an entire reproductive cycle for females and for 5 months for males. Crossed-fertilizations were carried out in order to obtain 4 groups of offspring. Offspring were fed with a commercial diet until they reached a market size. At this stage, hepatic transcriptomes were compared to detect any impact of the parental diet on offspring metabolism.

Programming of the hepatic lipid metabolism via a parental high carbohydrate low protein diet in rainbow trout

Project description:In rainbow trout (Oncorhynchus mykiss), the effect of a paternal and a maternal high carbohydrate-low protein diet was assessed on progeny at long term. To this purpose, two-year old male and female rainbow trout were fed either a control diet or a high carbohydrate/low protein diet for an entire reproductive cycle for females and for 5 months for males. Crossed-fertilizations were carried out in order to obtain 4 groups of offspring. Offspring were fed with a commercial diet until they reached a market size and were then challenged with a complete plant-based diet for 3 months. After the challenge, hepatic transcriptomes were analysed to detect any effect of the parental diet on offspring metabolism.

No adverse effect of a parental low protein/high carbohydrate diet on their offspring, in rainbow trout (muscle)

Project description:In rainbow trout (Oncorhynchus mykiss), the effect of a paternal and a maternal high carbohydrate-low protein diet was assessed on progeny at long term. To this purpose, two-year old male and female rainbow trout were fed either a control diet or a high carbohydrate/low protein diet for an entire reproductive cycle for females and for 5 months for males. Crossed-fertilizations were carried out in order to obtain 4 groups of offspring. Offspring were fed with a commercial diet until they reached a market size. At this stage, muscle transcriptomes were analysed to detect any effect of the parental diet on offspring metabolism.

Gene expression in Rainbow trout (Oncorhynchus mykiss) fry gonads after a chronic exposure to a range of 17?-ethynylestradiol concentrations

Project description:Sex steroids play a key role in triggering sec differentiation in fish and the use of exogenous hormone treatment leads to partial or complete sex reversal. This phenomenon has attracted attention since the discovery taht even low environmental doses of exogenous steroids can adversely affect gonad morphology (ovotestis development) and induce reproductive failure. Modern genomic-based technologies have enhanced opportunities to find mechanisms of action (MOA) and dentify biomarkers for the toxic action of a compound. The goal of this study are to improve the understanding of feminization in fish by analyzing gene expression patterns in the gonads of rainbow trout fry after a chronic exposure to several doses (0.01, 0.1, 1 and 10 ?g/L) of ethynylestradiol (EE2) and to offer target genes as potential biomarkers of ovotestis development. An all-male population of Rainbow trout fry was exposed during 76 days (from 60 to 136 days post-fertilization (dpf)) to five nominal concentrations of 17?-ethynylestradiol (0-solvent control-, 0.01, 0.1, 1 and 10 ?g EE2/L of water), using 3 tanks per condition. In total, 30 samples were analyzed independantly: 6 samples per concentration tested (two samples per tank, three tanks per concentration), each sample being a pool of 10 pairs of gonads.
