Melatonin is a ubiquitous molecule present in almost every live being from bacteria to
humans. In vertebrates, besides being produced in peripheral tissues and acting as an …

Many of melatonin's actions are mediated through interaction with the G-protein coupled
membrane bound melatonin receptors type 1 and type 2 (MT1 and MT2, respectively) or …

The neuromodulator melatonin synchronizes circadian rhythms and related physiological
functions through the actions of two G-protein-coupled receptors: MT1 and MT2. Circadian …

Melatonin, N‐acetyl‐5‐methoxytryptamine, an evolutionally old molecule, is produced by the
pineal gland in vertebrates, and it binds with high affinity to melatonin receptors, which are …

Abstract Melatonin (N-acetyl-5-methoxytryptamine) has revealed itself as an ubiquitously
distributed and functionally diverse molecule. The mechanisms that control its synthesis …

Melatonin is a ubiquitous molecule and widely distributed in nature, with functional activity
occurring in unicellular organisms, plants, fungi and animals. In most vertebrates, including …

Melatonin, dubbed the hormone of darkness, is known to regulate a wide variety of
physiological processes in mammals. This review describes well-defined functional …

OBJECTIVE: To summarize the role of melatonin in the physiology and pathophysiology of
the ovary. DESIGN: Review of literature. SETTING: University Health Science Center …

The circadian release of the hormone melatonin is regulated by the suprachiasmatic
nucleus (SCN), which feeds back into the nucleus to modulate sleep and circadian phase …

This review summarizes new findings related to beneficial effects of melatonin (N-acetyl-5-
methoxytryptamine) on reproductive physiology. Recently many researchers have begun to …
