Why the study?
Does overexpression of TGF-beta1 induce cardiac hypertrophy and alter beta-adrenergic signaling in vivo?
Does overexpression of TGF-beta1 induce cardiac hypertrophy and alter beta-adrenergic signaling in vivo?
In vivo overexpression of TGF-beta1 induces cardiac hypertrophy and enhances beta-adrenergic signaling, suggesting a mechanism for excessive catecholamine stimulation during the transition to heart failure.
