Norepinephrine can stimulate apoptosis in adult rat ventricular myocytes by activation of the β-adrenergic pathway.

Somatostatin (GHIH), a peptide hormone, regulates the endocrine system and affects neural transmission and cell proliferation by interacting with G-protein-coupled somatostatin receptors and inhibiting the release of multiple secondary hormones. Somatostatin inhibits secretion of insulin and glucagon.
