Swimming-induced modulation of the skeletal muscle transcriptome in rainbow trout

Swimming is an integral part of the behavior of many species of fish and is accomplished through the contractile activity of skeletal muscle. In turn, swimming-induced contractile activity modulates the skeletal muscle phenotype. In salmonid fish, swimming under sustainable speeds may promote somatic growth by a complex interaction of factors including increased feed intake, feed conversion and nutrient utilization rates, as well as contraction-induced adaptive mechanisms at the molecular and cellular levels in skeletal muscle. In this talk, I will discuss recent data from my laboratory on the transcriptomic response of skeletal muscle to swimming-induced activity in rainbow trout (Oncorhynchus mykiss) using microarray analysis and RNAseq.
