Kisspeptin system in pejerrey fish (Odontesthes bonariensis). Characterization and gene expression pattern during early developmental stages
(Elsevier Science Inc, 2017-02)
In vertebrates, kisspeptins and their receptors are known to be related to puberty onset and gonadal maturation, however, there are few studies concerning their role in early development. Here, we characterize the kisspeptin ...
Evidence for a celiac ganglion-ovarian kisspeptin neural network in the rat: Intraovarian anti-kisspeptin delays vaginal opening and alters estrous cyclicity
(2012)
Kisspeptin and its receptor GPR54 have been described as key hypothalamic components in the regulation of GnRH secretion. Kisspeptin is also present in several regions of the central nervous system and the peripheral organs ...
Participação dos receptores para esteróides ovarianos na ação da kisspeptina sobre neurônios dopaminérgicos e secreção de prolactina
(Universidade Federal de Minas GeraisUFMG, 2013-04-03)
We have shown that kisspeptin stimulates prolactin (PRL) secretion in an estradiol-dependent manner through inhibition of dopaminergic terminals in the median eminence (ME). The effects of estradiol may occur via estrogen ...
Unraveling the connection between GABA and kisspeptin in the control of reproduction
(BioScientifica, 2019-06)
Neuroendocrine control of reproduction involves the interplay of various factors that become active at some point along development. GnRH is the main neurohormone controlling reproduction and among the most important inputs ...
Hypothalamic transcriptional expression of the kis-speptin system and sex steroid receptors differs among polycystic ovary syndrome rat models with different endocrine phenotypes
(Hospital Clinicas, Univ Sao Paulo, 2017)
OBJECTIVES: Polycystic ovary syndrome is a heterogeneous endocrine disorder that affects reproductive-age women. The mechanisms underlying the endocrine heterogeneity and neuroendocrinology of polycystic ovary syndrome are ...
Hypothalamic transcriptional expression of the kis-speptin system and sex steroid receptors differs among polycystic ovary syndrome rat models with different endocrine phenotypes
(Hospital das Clínicas de Universidade São Paulo, 2017)
OBJECTIVES: Polycystic ovary syndrome is a heterogeneous endocrine disorder that affects reproductive-age women. The mechanisms underlying the endocrine heterogeneity and neuroendocrinology of polycystic ovary syndrome are ...
Kisspeptin level in the aging ovary is regulated by the sympathetic nervous system
(BioScientifica Ltd., 2017)
Previous work has demonstrated that the increase in the activity of sympathetic nerves, which occurs during the subfertility period in female rats, causes an increase in follicular cyst development and impairs follicular ...
Kisspeptin and GnRH interactions in the reproductive brain of teleosts
(Academic Press Inc Elsevier Science, 2020-11-01)
It is well known that gonadotropin-releasing hormone (Gnrh) has a key role in reproduction by regulating the synthesis and release of gonadotropins from the anterior pituitary gland of all vertebrates. About 25 years ago, ...
Kisspeptin is involved in ovarian follicular development during aging in rats
(Bioscientifica, 2016)
We have previously reported that kisspeptin (KP) may be under the control of the sympathetic
innervation of the ovary. Considering that the sympathetic activity of the ovary increases with aging,
it is possible that ...
Participación de kisspeptina en la función ovárica y sus cambios durante la activación del sistema nervioso simpático inducida por el estrés por frío en la rata
(Universidad de Chile, 2013-01)
Kisspeptina es un péptido de 145 aa. el cual juega un rol clave en la secreción de GnRH, participando en conjunto con las catecolaminas en la regulación de la ovulación a nivel hipotalámico. La mayoría de las neuronas ...
