abstract：:Beta(1)- and beta(2)-adrenergic receptors (betaARs) are known to differentially regulate cardiomyocyte contraction and growth. We tested the hypothesis that these differences are attributable to spatial compartmentation of the second messenger cAMP. Using a fluorescent resonance energy transfer (FRET)-based approach, ...
