Murine Echocardiography and Ultrasound Imaging

This video demonstrates use of a rail-mounted high-frequency ultrasound probe to perform echocardiography on an anesthetized mouse. The methods describe both conventional two-dimensional and M-mode measurements of cardiac function in addition to newer, more powerful tools such as color Doppler, strain analysis, as well as general and targeted contrast imaging.

Small Molecule Disruption of G Beta Gamma Signaling Inhibits the Progression of Heart Failure
Excess signaling through cardiac Gbetagamma subunits is an important component of heart failure (HF) pathophysiology. They recruit elevated levels of cytosolic G protein-coupled receptor kinase (GRK)2 to agonist-stimulated beta-adrenergic receptors (beta-ARs) in HF, leading to chronic beta-AR desensitization and downregulation; these events are all hallmarks of HF. Previous data suggested that inhibiting Gbetagamma signaling and its interaction with GRK2 could be of therapeutic value in HF.
