Riferimento:Int J Biol Markers. 1988 Apr-Jun;3(2):82-6.Azione della melatonina:Metastatic patients had lower melatonin levels and a lower T4/T8 ratio.Target:MLT/ beta-endorphin
Anno: 1989

Riferimento:Arch Histol Cytol. 1989;52 Suppl:69-74.Azione della melatonina:Serotonin is one of the representative biogenic amines produced from tryptophan in the gastrointestinal tract as well as in the brain. The capacity to synthesize serotonin depends on the existence of tryptophan monooxygenase. The activity of tryptophan monooxygenase in paraneurons such as mastocytomas and enterochromaffin cells depends on available ferrous iron.Target:L-5HTP monooxygenase.
