Melatonin Metabolism: Neural
Regulation of Pineal Serotonin:
Acetyl Coenzyme A
N-acetyltransferase Activity
David C. Klein, Joan L. Weller, and
Robert Y. Moore
These data indicate that superior cervical
sympathectomy abolishes the N-acetyl-transferase
rhythm by elimination of the input of central signals
to the gland. These signals appear to regulate the
N-acetyltransferase rhythm in the normal rat by
regulation of the release of norepinephrine from the
sympathetic terminals within the pineal gland.
