From the authors: “This study uses a mouse model of chronic [G protein-coupled receptor kinase 2 (GRK2)] overactivity to further investigate the consequences of long-term GRK2 on cardiac function and structure. We report for the first time that chronic GRK2 overactivity was able to cause cardiac dysfunction and remodeling independent of surgical intervention, highlighting the importance of GRK activity in aged-related heart disease.” 

This study is highlighted as one of May's "best of the best" as part of the American Physiological Society's APSselect program.
