Effect of dietary methionine level on muscle growth mechanisms in juvenile rainbow trout ( Oncorhynchus mykiss )

The aim of the study was to analyse the effects of different dietary methionine (Met) concentrations on the mechanisms of fish muscle growth (hyperplasia and hypertrophy) by using cellular and molecular approaches. Three plant-based diets differing by their Met level (MD, Met-deficient; MC, Met-control, corresponding to established Met requirement; MH, Met-high) were fed to rainbow trout juveniles for 12 weeks. Met deficiency led to a reduced...
