May reduce betaARK1 to mediate beta-blocker benefits in HF; leaves open translation from animal models to humans.
Does beta-adrenergic receptor stimulation or blockade alter the in vivo expression of betaARK1?
Demonstrates a novel mechanism of ligand-induced betaAR regulation where beta-blockade decreases betaARK1 expression, providing insight into the efficacy of beta-blockers in heart failure.
Iaccarino et al. (1998) studied this question.
