Microarray gene expression profiles from temperature acclimated atrial, ventricular compact and spongy tissues of Pacific bluefin tuna Thunnus orientalis

ABSTRACT: In this study, we examined the transcriptomic responses to temperature acclimation (14oC, 20oC, and 25oC) in atrial and ventricular tissues of Pacific bluefin tuna (PBFT). A global gene expression analysis using a bluefin tuna-specific microarray indicated profound changes in expression of genes associated with energy metabolism, protein turnover, cellular stress response, oxidative stress and apoptosis. A principal component analysis revealed tissue-specific transcriptomic responses to temperature, with atrium at 25oC showing the greatest variation. Overall transcriptomic data suggests that PBFT can optimize cardiac function in the cold by acclimating to 14oC. Capacity to acclimate to colder temperatures potentially underlies this species ability to expand its vertical and horizontal ther
