WebAbstract. In rat pinealocytes, an increase in intracellular Ca2+ concentration ( [Ca2+]i) due to Ca2+ influx in response to norepinephrine (NE) is a well recognized event involved in regulating several metabolic functions. Since NE also stimulates the metabolism of phosphatidyl inositols in rat pineal gland, it is conceivable that Ca2+ release ...
