    • Circadian clocks during embryonic and fetal development 
      Serón Ferré, María; Valenzuela, Gullermo J.; Torres Farfán, Claudia (2007)
      Circadian rhythmicity is a fundamental characteristic of organisms, which helps ensure that vital functions occur in an appropriate and precise temporal sequence and in accordance with cyclic environmental changes. Living ...
    • Circadian rhythms in the fetus 
      Serón Ferré, María; Méndez, Natalia; Abarzúa Catalán, Lorena; Vilches, Nelson; Valenzuela, Francisco J.; Reynolds, Henry E.; Llanos Mansilla, Jorge; Rojas, Auristela; Valenzuela, Guillermo J.; Torres Farfán, Claudia (Elsevier, 2012)
      Throughout gestation, the close relationship between mothers and their progeny ensures adequate development and a successful transition to postnatal life. By living inside the maternal compartment, the fetus is inevitably ...
    • Cryptochrome 2 expression level is critical for adrenocorticotropin stimulation of cortisol production in ... 
      Torres Farfán, Claudia; Abarzúa Catalán, Lorena; Valenzuela, F. J.; Mendez, N.; Richter, H. G.; Valenzuela, G. J.; Serón Ferré, María (2009)
      Timely production of glucocorticoid hormones in response to ACTH is essential for survival by coordinating energy intake and expenditure and acting as homeostatic regulators against stress. Adrenal cortisol response to ...
    • Developmental Programming of Capuchin Monkey Adrenal Dysfunction by Gestational Chronodisruption 
      Richter, Hans G.; Mendez, Natalia; Abarzúa Catalán, Lorena; Valenzuela, Guillermo J.; Serón Ferré, María; Torres Farfán, Claudia (Hindawi Limited, 2018)
      © 2018 Hans G. Richter et al. In the capuchin monkey (Cebus apella), a new-world nonhuman primate, maternal exposure to constant light during last third of gestation induces precocious maturation of the fetal adrenal and ...
    • Impact of Chronodisruption during Primate Pregnancy on the Maternal and Newborn Temperature Rhythms 
      Serón Ferré, María; Forcelledo, María Luisa; Torres Farfán, Claudia; Valenzuela, Francisco J.; Rojas, Auristela; Vergara, Marcela; Rojas García, Pedro; Recabarren, Mónica P.; Valenzuela, Guillermo J. (PLoS ONE, 2013)
      Disruption of the maternal environment during pregnancy is a key contributor to offspring diseases that develop in adult life. To explore the impact of chronodisruption during pregnancy in primates, we exposed pregnant ...
    • La melatonina reduce la respuesta de cortisol al ACTH en humanos 
      Campino, Carmen; Valenzuela, Francisco; Arteaga, Eugenio; Torres Farfán, Claudia; Trucco, Cristián; Velasco, Alfredo; Guzmán, Sergio; Serón Ferré, María (SOC MEDICA SANTIAGO, 2008-11)
      Background: Melatonin receptors are widely distributed in human tissues but they have not been reported in human adrenal gland. Aim: To assess if the human adrenal gland expresses melatonin receptors and if melatonin affects ...
    • Maternal chronodisruption throughout pregnancy impairs glucose homeostasis and adipose tissue physiology ... 
      Halabi, Diego; Richter, Hans G.; Méndez, Natalia; Kahne, Thilo; Spichiger, Carlos; Salazar, Esteban; Torres, Fabiola; Vergara, Karina; Serón Ferre, María Josefa; Torres Farfán, Claudia (Frontiers Media, 2021)
      Compelling evidence in rats support the idea that gestational chronodisruption induces major changes in maternal circadian rhythms and fetal development and that these changes impact adult life at many physiological levels. ...
    • Melatonin exerts direct inhibitory actions on ACTH responses in the human adrenal gland 
      Campino, C.; Valenzuela, F. J.; Torres Farfán, Claudia; Reynolds, H. E.; Abarzúa Catalán, Lorena; Arteaga, E.; Trucco, C.; Guzmán, S.; Valenzuela, G. J.; Serón Ferré, María (2011)
      In nonhuman primates and rodents, melatonin acting directly on the adrenal gland, inhibits glucocorticoid response to ACTH. In these species, an intrinsic adrenal circadian clock is involved in ACTH-stimulated glucocorticoid ...
    • Melatonin reduces cortisol response to ACTH in humans La melatonina reduce la respuesta de cortisol al ACTH ... 
      Campino, Carmen; Valenzuela, Francisco; Arteaga, Eugenio; Torres Farfán, Claudia; Trucco, Cristián; Velasco, Alfredo; Guzmán, Sergio; Serón Ferré, María (2008)
      Background: Melatonin receptors are widely distributed in human tissues but they have not been reported in human adrenal gland. Aim: To assess if the human adrenal gland expresses melatonin receptors and if melatonin affects ...
    • Mt1 melatonin receptor in the primate adrenal gland: Inhibition of adrenocorticotropin-stimulated cortisol ... 
      Torres Farfán, Claudia; Richter, Hans G.; Rojas García, Pedro; Vergara, Marcela; Forcelledo, María Luisa; Valladares Boasi, Luis; Torrealba, Fernando; Valenzuela, Guillermo J.; Serón Ferré, María (2003)
      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 ...
    • Timed maternal melatonin treatment reverses circadian disruption of the fetal adrenal clock imposed by ... 
      Méndez, Natalia; Abarzúa Catalán, Lorena; Vilches, Nelson; Galdames, Hugo A.; Spichiger, Carlos; Richter, Hans G.; Valenzuela, Guillermo J.; Serón Ferré, María; Torres Farfán, Claudia (2012)
      Surprisingly, in our modern 24/7 society, there is scant information on the impact of developmental chronodisruption like the one experienced by shift worker pregnant women on fetal and postnatal physiology. There are ...
