    Abstract: A bstract : The embryonic development of the circadian melatonin (MT) rhythm and the responsiveness of embryonic MT secretion to pituitary adenylate cyclase‐activating polypeptide (PACAP) were investigated. Using dynamic in vitro bioassays, we showed the following: (1) The circadian clock and/or the intracellular signal transduction pathways connecting the clock to the MT synthesizing apparatus appear between days 16 and 18 (E16‐18) of embryonic development. Lack of periodical environmental stimuli can lead to a delay in this maturation. (2) Exposure of the embryonic chicken pineal gland to PACAP induces a transitory increase in MT secretion and (3) a transitory increase in cyclic AMP efflux at or before day E13 in vitro .

    Abstract: Abstract:  The effects of in vitro VIP administration and those of in ovo pretreatment with PACAP antagonist (PACAP6‐38) on the development of the embryonic melatonin (MT) secretion were investigated. With dynamic in vitro bioassay we showed that (1) the development of the circadian MT secretion seems to be unaffected by VIP administrations or by PACAP6‐38 pretreatments; (2) exposure of the embryonic chicken pineal gland to VIP induces transitory increase in MT secretion at or before the 14th embryonic day in vitro .

    Abstract: A bstract : The effects of different environmental factors on the circadian rhythm of melatonin release by chicken pineal glands were analyzed in 5‐day experiments in vitro . Periodic, brief 4‐h illumination at around midnight resulted in phase inversion in 2 days. Exposure to repeated 41°C temperature elevation at around midnight caused no phase shift in the basic melatonin rhythm. Repeated inversion of the polarity of the magnetic field also affected rhythmic melatonin release. Additionally, expressions of Per1, Per2, Per3, Bmal1, Bmal2, Clock, Cry1, and Cry2 clock genes were simultaneously detected in single chicken pineal glands.
