Implication

Suggests apoptosis as a potential therapeutic target in heart failure; leaves open clinical translation of beta-adrenergic modulation.

Key Points

To explore how adrenergic signaling affects apoptosis in cardiac myocytes and contributes to heart failure.
In vitro pharmacologic studies of cardiac myocytes were conducted.
Transgenic mice overexpressing beta 1-adrenergic receptors were analyzed for apoptosis.
Investigated the roles of various G-protein coupled receptors in mediating apoptosis.
Beta-1 adrenergic receptors significantly stimulate apoptosis in cardiac myocytes in vitro and in vivo.
Beta-2 adrenergic receptors can either stimulate or inhibit apoptosis based on expression levels.
Interactions between adrenergic receptors and Gi/Gq signaling pathways play a role in myocyte apoptosis and myocardial failure.

Population

Cardiac myocytes in vitro and transgenic mice models (overexpression of beta 1-AR or G alpha s)

Intervention

Adrenergic pathway activation (norepinephrine, beta-adrenergic receptor stimulation)

Outcome

Myocyte apoptosis and development of myocardial failure

Adrenergic nervous system activation, a hallmark of heart failure, regulates myocyte apoptosis primarily through beta-adrenergic receptor and G-protein signaling pathways.

Krishna Singh (2000) conducted a review in Heart failure and myocardial apoptosis. Adrenergic pathway signaling was evaluated on Myocyte apoptosis and development of myocardial failure. Adrenergic nervous system signaling, particularly via beta-adrenergic receptors and G-proteins, regulates cardiac myocyte apoptosis and may contribute to the development of myocardial failure.
