Abstract
The protein kinase product of the gene mutated in myotonic dystrophy 1 (DMPK) is reported to play a role in cardiac pathophysiology. To gain insight into the molecular mechanisms modulated by DMPK, we characterize the impact of DMPK ablation in the context of cardiac β-adrenergic function. Our data demonstrate that DMPK knockout mice present altered β-agonist-induced responses and suggest that this is due, at least in part, to a reduced density of β 1-adrenergic receptors in cardiac plasma membranes.
