However, chronic up-regulation of the isoform could taxes hearts experiencing cellular stress further, and trigger deterioration in myocardial energetics and impair pump performance ultimately. Future models are needed to explain these seemingly divergent results and the inability to capture changes in downstream target phosphorylation. A stochastic model incorporating the enhanced phosphorylation turnover detected here is a logical starting point.5, and NCX. 4) compared to the basal state. Complex patterns of downstream target phosphorylation are associated with both basal and agonist-stimulated conditions. Testable models are needed to understand the relationship between the contractile function and end target phosphorylation responses.Get regular physical exercise each full day, preferably 40 minutes every day of an activity that causes sweating..
