Phosphodiesterase 4D Regulates Baseline Sarcoplasmic Reticulum Ca2+ Release and Cardiac Contractility, Independently of L-Type Ca2+ Current

Abstract

RATIONALE: Baseline contractility of mouse hearts is modulated in a phosphatidylinositol 3-kinase-γ-dependent manner by type 4 phosphodiesterases (PDE4), which regulate cAMP levels within microdomains containing the sarcoplasmic reticulum (SR) calcium ATPase type 2a (SERCA2a). OBJECTIVE: The goal of this study was to determine whether PDE4D regulates basal cardiac contractility.
