K.S. Bishnupuri,Chandana Haldar +1 more
TLDR
The results support the earlier concept and show for the first time that MEL can be transported from the mother to the young either prenatally through the placenta or postnatally via the milk in order to influence neonatal growth and sexual maturation.Abstract:
To date, the phenomenon of maternal transfer of hormones to the young is an enigma. The present study explains for the first time the maternal transfer of melatonin (MEL) to the young, affecting neonaread more

Human placental trophoblasts synthesize melatonin and express its receptors.
TL;DR: A local synthesis of melatonin and expression of its receptors in human trophoblasts is demonstrated for the first time and strongly suggests a paracrine, autocrine, and/or intracrine role for this indolamine in placental function and development as well as in protection from oxidative stress.

Neuroendocrine and immune relationships in postpartum fatigue.
TL;DR: The data suggest that fatigue, stress, depression, and infection are related in postpartum mothers and that these relationships extend to levels of serum hormones and milk factors.

Expression of melatoninergic receptors in human placental choriocarcinoma cell lines
TL;DR: These results demonstrate, for the first time, the expression of melatonin receptors in human term placental tissues and in choriocarcinoma cells and suggest a possible paracrine/autocrine function for melatonin in human placenta.

Physiological crosstalk between melatonin and glucocorticoid receptor modulates T-cell mediated immune responses in a wild tropical rodent, Funambulus pennanti.
Sameer Gupta,Chandana Haldar +1 more
TL;DR: It may be suggested that a physiological cross talk exist between Mel and GR which is of high adaptive significance in wild animals for balancing the immunity during ecologically stressful conditions.

Protein Measurement with the Folin Phenol Reagent
TL;DR: Procedures are described for measuring protein in solution or after precipitation with acids or other agents, and for the determination of as little as 0.2 gamma of protein.

Radioimmunoassay of serum concentrations of melatonin in sheep exposed to different lighting regimens.
M. D. Rollag,Gordon D. Niswender +1 more
TL;DR: A precipitous drop in serum concentrations of melatonin resulted when ewes experiencing peak melatonin concentrations were exposed to light and returned to peak levels when the lights were turned off 3.5 h later.

Melatonin receptors: Localization, molecular pharmacology and physiological significance
TL;DR: Evidence indicates that melatonin acts to inhibit intracellular cyclic AMP through a G-protein coupled mechanism, demonstrating that this is a common signal transduction pathway for many melatonin receptors.

Effect of melatonin on the reproductive systems of male and female Syrian hamsters: a diurnal rhythm in sensitivity to melatonin.
TL;DR: It is indicated that chronic daily injections of melatonin can depress reproductive function in hamsters and that the effectiveness of the injections is dependent upon the time of day at which they are administered.
Journal ArticleDOI
Antigonadal effects of timed melatonin infusion in pinealectomized male Djungarian hamsters (Phodopus sungorus sungorus): duration is the critical parameter.
TL;DR: The hypothesis that melatonin mediates the pineal-antigonadal effects of short day exposure in the Djungarian hamster is supported and the data strongly suggest that duration is the feature of nighttime melatonin release that is most important for photoperiodic time measurement in this species.
