Abstract excerpt
RATIONALE: Both β-adrenergic receptor (β-AR) and Gq-coupled receptor (GqR) agonist-driven signaling play key roles in the events, leading up to and during cardiac dysfunction. How these stimuli interact at the level of protein kinase D (PKD), a nodal point in cardiac hypertrophic signaling, remains unclear. OBJECTIVE: To assess the spatiotemporal dynamics of PKD activation in response to β-AR signaling alone and...
