Vasopressinergic Activity of the Suprachiasmatic Nucleus and mRNA Expression of Clock Genes in the Hypothalamus-Pituitary-Gonadal Axis in Female Aging
(2021-08-24)
The important involvement of the suprachiasmatic nucleus (SCN) and the activity of vasopressinergic neurons in maintaining the rhythmicity of the female reproductive system depends on the mRNA transcription-translation ...
Chronic Stress and Ovulatory Dysfunction: Implications in Times of COVID-19
(2022)
Stress is known to be associated with adverse health outcomes. The COVID-19 pandemic and its associated lockdowns are examples of chronic stressors. Lockdown measures inadvertently caused significant psychological distress ...
Variação na resposta à kisspeptina para avaliação de precocidade sexual em novilhas nelore
(Universidade Estadual Paulista (Unesp), 2018-06-29)
Objetivou-se comparar a concentração de LH plasmático, em resposta à kisspeptina exógena, em novilhas Nelore, para avaliar a maturação sexual do Sistema Nervoso Central. As hipóteses testadas foram de que em resposta a ...
Multiple failures in the lutenising hormone surge generating system in GABAB1KO female mice
(Wiley Blackwell Publishing, Inc, 2019-09)
Female mice lacking GABAB receptors, GABAB1KO, show disrupted oestrous cycles, reduced pregnancies and increased hypothalamic Gnrh1 mRNA expression, whereas anteroventral periventricular/periventricular preoptic nucleus ...
Leptin signaling in Kiss1 neurons arises after pubertal development
(Public Library Science, 2013-03-07)
The adipocyte-derived hormone leptin is required for normal pubertal maturation in mice and humans and, therefore, leptin has been recognized as a crucial metabolic cue linking energy stores and the onset of puberty. ...

Participation of TRPV1 in the activity of the GnRH system in male rats
(Wiley Blackwell Publishing, Inc, 2020-05)
GnRH neuron activity is under the influence of multiple stimuli, including those coming from the endocannabinoid and the immune systems. Since it has been previously suggested that some of the main elements controlling the ...
Evidence of alternative splicing as a regulatory mechanism for KISSR2 in pejerrey fish
(Frontiers Media S.A., 2018-10)
Kisspeptin receptors are G-Protein-Coupled Receptors that regulate GnRH synthesis and release in vertebrates. Here, we report the gene structure of two kisspeptin receptors (kissr2 and kissr3) in pejerrey fish. Genomic ...
Participación de Kisspeptina en el reclutamiento folicular durante el envejecimiento ovárico
(Universidad de Chile, 2016)
En la actualidad las parejas deciden postergar la maternidad más allá de los 30 años de edad, acercándose a la ventana de subfertilidad de la mujer. Este cambio en la conducta de la población disminuye la probabilidad de ...
