mt1 Melatonin Receptor in the Primate Adrenal Gland: Inhibition of Adrenocorticotropin-Stimulated Cortisol Production by Melatonin

Abstract: The pineal hormone melatonin participates in circadian, seasonal, and reproductive physiology. The presence of melatonin binding sites in human brain and peripheral tissues is well documented. However, in the mammalian adrenal gland, low-affinity melatonin binding sites have been detected only in the rat by some but not all authors. Conflicting evidence for a regulatory role of melatonin on adrenal cortisol production, prompted us to investigate this possibility in a New World primate, the capuchin monkey. Exp… Show more

“…It is worthy of mention that melatonin is also capable of modulating the production of adrenal GCs. In humans and monkeys, acute melatonin administration suppresses the production of cortisol (Torres-Farfan et al 2003, Campino et al 2011. More recently, it has been demonstrated using foetal rats that timed melatonin application can entrain adrenal gland rhythms .…”

“…En cambio detectamos la expresión de mARN para el receptor MT1 y MT2 en el tejido humano renal como ha sido previamente publicado 21 y fue usado como control positivo. Estos resultados son similares a los observados por nosotros en la corteza suprarrenal de la rata y del mono capuchino [8][9][10] .…”

“…En humanos, ambos receptores de melatonina están presentes en tejidos esteroidogé-nicos como la placenta y células de la granulosa 4,5 . Adicionalmente, estudios realizados en animales demuestran la presencia solo del receptor MT1 en las células de Leydig de la rata y hamster y en la glándula suprarrenal de rata adulta y de fetos y adultos de primates no humanos [6][7][8][9][10] . En esta última glándula, la melatonina inhibe la expresión de genes circadianos 11 y también la producción de cortisol estimulada por ACTH 9,10 .…”
