Peripheral and central mechanisms involved in hormonal control of male and female reproduction [PDF]
, 2016 Reproduction involves the integration of hormonal signals acting across multiple systems togenerate a synchronized physiological output. A critical component of reproduction is the luteinizinghormone (LH) surge, which is mediated by estradiol (E2) and ...

The potential anti-cancer effects of melatonin on breast cancer
Exploration of Medicine, 2022 Melatonin is the primary hormone of the pineal gland that is secreted at night. It regulates many physiological functions, including the sleep-wake cycle, gonadal activity, free radical scavenging, immunomodulation, neuro-protection, and cancer ...

Melatonin receptor depletion suppressed hCG-induced testosterone expression in mouse Leydig cells
Cellular & Molecular Biology Letters, 2019 Melatonin receptors MT1 and MT2 (genes officially named MTNR1A and MTNR1B, respectively) play crucial roles in melatonin-mediated regulation of circadian rhythms, the immune system, and control of reproduction in seasonally breeding animals.

Neurosignals, 1993 High-affinity melatonin receptors are expressed in the tail artery of the rat and arteries forming the circle of Willis of the rat and certain primates. The characteristics of the vascular melatonin receptors seem to be similar to the ones described in the central nervous system.

The direct response of the gonads to cues of stress in a temperate songbird species is season-dependent. [PDF]
, 2013 The gonadotropin releasing hormone (GnRH) system in the hypothalamus is often considered the final point in integration of environmental cues as they pertain to the reproductive axis.

Annals of Medicine, 1998 Melatonin is produced rhythmically by the pineal gland and the retina with increased synthesis during darkness. Pineal melatonin serves as the 'chemical expression of darkness' conveying information on the ambient light-dark cycle into rhythmic bodily functions.

Circadian regulation of reproduction: From gamete to offspring [PDF]
, 2013 P01326625; Grants: GNT0519315Few challenges are more critical to the survival of a species than reproduction. To ensure reproductive success, myriad aspects of physiology and behaviour need to be tightly orchestrated within the animal, as well as timed ...

Melatonin increases growth properties in human dermal papilla spheroids by activating AKT/GSK3β/β-Catenin signaling pathway [PDF]
PeerJ, 2022 Background Melatonin, a neurohormone, maybe involved in physiological processes, such as antioxidation, anti-inflammation, and hair growth. In the present study, we investigated the effects of melatonin on proliferation and intracellular signaling in DP ...

Myopes have significantly higher serum melatonin concentrations than non-myopes [PDF]
, 2017 Purpose Experimental animal models of myopia demonstrate that higher melatonin (Mel) and lower dopamine (DA) concentrations actively promote axial elongation.
