Deskripsi
The stroke volume of the heart increases in response to an increase in the blood volume filling the heart. Here the authors reveal that this coordinated process is mediated in part by oxidative activation of the protein kinase G Iα, which phosphorylates phospholamban to enhance diastolic relaxation in mice.
