Advanced Science, Volume 12, Issue 17, May 8, 2025.Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...
