Journal ArticleDOI
Environmental control of biological rhythms: effects on development, fertility and metabolism.
Fernanda Gaspar do Amaral,Ana Maria de Lauro Castrucci,José Cipolla-Neto,Maristela O. Poletini,Natalia Mendez,Hans Richter,Michael T. Sellix +6 more
TL;DR: Pernicious alterations of the endogenous temporal order by environmental factors can disrupt the homeostatic function of the circadian timing system, leading to pathophysiology and/or disease.
Journal ArticleDOI
Changes in α-estradiol receptor and progesterone receptor expression in the locus coeruleus and preoptic area throughout the rat estrous cycle
C. V. V. Helena,Maristela O. Poletini,Gilberto Luiz Sanvitto,Shinji Hayashi,Celso Rodrigues Franci,Janete Aparecida Anselmo-Franci +5 more
TL;DR: Data show that LC neurons express ER and PR and seem to be more sensitive to variations in estradiol than POA, which might be related to the ability ofEstradiol and progesterone in regulating the activity of LC neurons, which could be associated to the control mechanisms of LH and prolactin release.
Journal ArticleDOI
Release of norepinephrine in the preoptic area activates anteroventral periventricular nucleus neurons and stimulates the surge of luteinizing hormone.
Raphael E. Szawka,Maristela O. Poletini,Maristela O. Poletini,Cristiane M. Leite,Marcelo Picinin Bernuci,Bruna Kalil,Leonardo B. D. Mendonça,Ruither O. G. Carolino,C. V. V. Helena,Richard Bertram,Celso Rodrigues Franci,Janete Aparecida Anselmo-Franci +11 more
TL;DR: Estradiol and progesterone activate A2 and LC neurons, respectively, and this is associated with the increased release of NE in the POA and the magnitude of the LH surge, which stimulates LH secretion, at least in part, through activation of anteroventral periventricular neurons.
Journal ArticleDOI
Anatomical and functional characterization of clock gene expression in neuroendocrine dopaminergic neurons.
Michael T. Sellix,Marcel Egli,Maristela O. Poletini,De’Nise T. McKee,M. Bosworth,Cheryl A. Fitch,Marc E. Freeman +6 more
TL;DR: The data suggest that clock gene expression, particularly PER1 and PER2, within NDNs may act to modulate diurnal rhythms of DA release from NDNs in the OVX rat.
Journal ArticleDOI
Oxytocin action at the lactotroph is required for prolactin surges in cervically stimulated ovariectomized rats.
TL;DR: The cervical stimulation-induced prolactin surges are maintained even in the absence of oxytocin actions at the lactotroph, which strongly suggests the maintenance of prolact in surges are not dependent upon oxytoc in action at the pituitary gland.
