Abstract

Norepinephrine (NE) regulates melatonin production and many other aspects of pineal function through actions involving cAMP. In the present study the effects of NE on the phosphorylation of the cAMP response element-binding protein (CREB) were studied to determine whether CREB phosphorylation might be involved in cAMP signal transduction in this tissue. CREB was detected using gel mobility-shift analysis with the radiolabeled Ca2+/cAMP response element of the c-fos promoter. CREB phosphorylation was estimated in the gel mobility-shift assay using an antiserum specific for phosphorylated CREB. This antiserum generates a supershifted CREB signal with protein extracts obtained from glands treated with NE (EC50 approximately equal to 10 nM) in organ culture, demonstrating that NE stimulates CREB phosphorylation. CREB phosphorylation peaks 30-45 min after NE treatment is initiated and then gradually returns to base-line values. Pharmacological studies show that NE-stimulated CREB phosphorylation is mediated primarily through beta 1-adrenergic receptor-stimulated increases in cAMP. Activation of alpha 1-adrenergic receptors, which is known to elevate the intracellular free Ca2+ concentration, does not cause CREB phosphorylation. However, it is possible to produce CREB phosphorylation with certain pharmacological agents that elevate the intracellular free Ca2+ concentration. In vivo studies show that CREB phosphorylation can be induced by treatment with isoproterenol (1 mg/kg), demonstrating that phosphorylation of pineal CREB occurs in intact animals. These studies indicate that cAMP-dependent CREB phosphorylation could play a role in the adrenergic regulation of gene expression in pinealocytes.
