Starting with the beginning of the last century, a multitude of scientific studies has
documented that the lunar cycle times behaviors and physiology in many organisms. It is …

Contents Melatonin and its receptors play a crucial role in the regulation of the animal
reproductive process, primarily in follicular development. However, the role that melatonin …

Circalunar clocks, which allow organisms to time reproduction to lunar phase, have been
experimentally proven but are still not understood at the molecular level. Currently, a new …

The hormone melatonin connects environmental cues, such as photoperiod and
temperature, with a number of physiological and behavioural processes, including seasonal …

Gonadotropin-releasing hormone (Gnrh) plays a major role in the regulation of physiological
and behavioural processes related to reproduction. In the pituitary, it stimulates …

The seasonal, daily and lunar control of reproduction involves photoperiodic, circadian and
lunar changes in the activity of kisspeptin, gonadotropin-inhibitory hormone (GnIH) and …

In order to improve our understanding of melatonin signaling, we have reviewed and revised
the evolutionary history of melatonin receptor genes (mtnr) in vertebrates. All gnathostome …

On one night per year, at a specific point in the lunar cycle, one of the most extraordinary
reproductive events on the planet unfolds as hundreds of millions of broadcast spawning …

Fish perceive environmental cues through sensory organs like the pineal gland and retina,
and transduce them as internal stimuli to activate an endocrine network known as the brain …

Melatonin receptors (MTNRs) belonging to the G protein-coupled receptor family are
considered to consist of three subtypes in vertebrates: MTNR1a, MTNR1b and MTNR1c …
