                                 Hormone Melatonin

Melatonin, also known as N-acetyl-5-methoxytryptamine, a hormone secreted by the pineal gland in the brain with functions of regulating sleep cycles, other hormones, timing in secretion of female hormones that affect the menstrual cycle, etc. The levels of the circulating hormone vary in a daily cycle, depending to the circadian rhythm is an internal 24-hour “clock”.

     Hormone Melatonin: Melatonin and circadian rhythms and sleep


Melatonin is an internal sleep "facilitator" in humans, and therefore useful in the treatment of insomnia and the readjustment of circadian rhythms. In the study of Role of melatonin in the regulation of human circadian rhythms and sleep, researchers found that administration of melatonin is able: (i) to induce sleep when the homeostatic drive to sleep is insufficient; (ii) to inhibit the drive for wakefulness emanating from the circadian pacemaker; and (iii) induce phase shifts in the circadian clock such that the circadian phase of increased sleep propensity occurs at a new, desired time(11).

     Hormone Melatonin: Tryptophan-enriched cereal intake in elderly humans

In the study to analyze whether the consumption of cereals enriched with tryptophan, the precursor of both serotonin and melatonin, may help in the reconsolidation of the sleep/wake cycle and counteract depression and anxiety in 35 middle-aged/elderly (aged 55-75 year) volunteers in a simple blind assay, showed that the consumption of cereals containing the higher dose in tryptophan increased sleep efficiency, actual sleep time, immobile time, and decreased total nocturnal activity, sleep fragmentation index, and sleep latency. Urinary 6-sulfatoxymelatonin, 5-hydroxyindoleacetic acid levels, and urinary total antioxidant capacity also increased respectively after tryptophan-enriched cereal ingestion as well as improving anxiety and depression symptoms. Cereals enriched with tryptophan may be useful as a chrononutrition tool for alterations in the sleep/wake cycle due to age(10).

     Hormone Melatonin: Direct involvement of melatonin in modulation of ovarian steroidogenesis

In the study to investigate the gene expression of the two different forms of melatonin receptors in human granulosa-luteal cells, using RT-PCR. PCR products corresponding to the expected sizes of the melatonin receptor subtypes, mt(1)-R and MT(2)-R, which were obtained from granulosa-luteal cells, and the authenticity of the PCR products was confirmed by Southern blot hybridization with cDNA probes, showed that melatonin treatment alone had no effect on basal progesterone production but enhanced the effects of human CG-stimulated progesterone production. Because MAPKs are activated in response to a diverse array of extracellular stimuli leading to the regulation of cell growth, division, and differentiation, and because melatonin has been shown to modulate cellular proliferation and differentiation. But melatonin activated MAPK in a dose- and time-dependent manner can regulate progesterone production, LH receptor, GnRH, and GnRH receptor gene expression through melatonin receptors in human granulosa-luteal cells, which may be mediated via the MAPK pathway and activation of Elk-1(9).

     Hormone Melatonin: Anti-depressant action of melatonin

In the study to investigate the antidepressant effect of physiological and pharmacological doses of melatonin in the Porsolt forced swimming-induced behavioral despair test, showed that acute administration of higher doses of melatonin (2.5-10 mg/kg) failed to induce any anti-depressant activity in mice which were subjected to forced swimming test for the first time. However, daily administration of melatonin (2.5-10 mg/kg) prior to swimming test significantly reversed the increase in immobility period that was observed on chronic exposure to swimming test. This effect was comparable with the effect of GABA-benzodiazepine (BZ) receptor agonists. Similarly, like GABAergic drugs, acute administration of melatonin also showed anti-depressant activity in a mice which were exposed to chronic forced swimming test(8).

In a study of "Decrease in melatonin precedes follicle-stimulating hormone increase during perimenopause" Olli Vakkuri, Aarre Kivelä, Juhani Leppäluoto, Maija Valtonen and Antti Kauppila, researchers found that the inverse changes in melatonin and FSH secretion during the perimenopausal years, with the sharpest decline in nocturnal excretion of melatonin far before menopause, suggest that melatonin may be permissively linked to the initiation of menopause.

Melatonin can enhance fertility of a woman by lowering Follicle stimulating hormones, according to the article of "You should know about Melatonin and Fertility" by Dr. Tanya Smith, TCM, ... at the 20th World Congress on Fertility and Sterility in September 2010 and found that the fertilization rate among women who took 3 mg tablets of melatonin (n = 56) during the second IVF cycle were improved compared with those achieved during their first failed cycle, at 50.0% versus 20.2%. Patients who did not take melatonin (n = 59) experienced no change in fertilization rates.

Melatonin has minor, if any, effect on TSH secretion whereas the effect on LH may depend on individual sensitivity.
