Abstract
- N-Acetyltransferase (NAT) activity at night and following isoproterenol treatment in intact animals was higher in rats pretreated with magnesium than in controls. This effect was probably due to enhancement of agonist binding and/or adenylate cyclase activation caused by magnesium ions. A similar effect was observed in vitro, where magnesium increased norepinephrine-stimulated NAT activity in organ-cultured pineal glands, suggesting that magnesium acts primarily on the pineal gland as opposed to some other peripheral or central site. This enhancement of NAT activity by magnesium would presumably lead to increased melatonin production; and as melatonin has been shown to decrease serum magnesium levels, a negative feedback mechanism may exist.
