Abstract
Pineal serotonin N-acetyltransferase (SNAT; E.C.2.3.1.5) activity was determined 3 times/day throughout the estrous cycle in rats exposed to 6L:18D or 14L:10D lighting conditions. The magnitude of increased SNAT activity measured during the dark phase of a photoperiod did not vary significantly throughout the estrous cycle in either photoperiod examined suggesting that SNAT does not regulate changes found in pineal melatonin content during the estrous cycle.This publication has 4 references indexed in Scilit:
