Both orexin receptors are expressed in rat ovaries and fluctuate with the estrous cycle. Effects of orexin receptor antagonists on gonadotropins and ovulation
(American Physiological Society, 2007-10)
Orexins are peptides controlling feeding, sleep, and neuroendocrine functions. They are synthesized by the hypothalamus with projections throughout the brain. Orexins and their orexin 1 (OX(1)) and orexin 2 receptors (OX(2)) ...
Neonatal androgenization-induced early endocrine–metabolic and ovary misprogramming in the female rat
(Pergamon-elsevier Science Ltd, 2015-06)
Aim: Androgen excess predisposes the organism to develop metabolic–endocrine and reproductive dysfunctions, among them the development of a phenotype resembling that of human Polycystic Ovary Syndrome (PCOS).
Methods: ...
Angiopoietins/TIE2 system and VEGF are involved in ovarian function in a DHEA rat model of Polycystic Ovary Syndrome
(Endocrine Society, 2012-07)
Polycystic ovary syndrome (PCOS) is the most common endocrinological pathology among women of reproductive age. It is characterized by anovulation, oligo- or amenorrhea, hyperandrogenism, obesity, and insulin resistance. ...
Structure of the gonoduct of the viviparous teleost Cnesterodon decemmaculatus (Jenyns, 1842) (Poeciliidae)
(Wiley-liss, div John Wiley & Sons Inc., 2021-04)
During embryogenesis, teleost females do not develop Müllerian ducts, which form the oviducts in all other vertebrates. Thus, when they reach sexual maturity they do not have oviducts. In viviparous teleosts, the lack of ...
Expression of melanocortin receptors mRNA, and direct effects of ACTH on steroids secretion in the bovine ovary
(Elsevier Science Inc, 2011-09)
Melanocortin receptors (MCRs) are involved in physiological responses to ACTH, as well as to α-, β- and γ-melanocyte-stimulating hormone (α-, β- and γ-MSH). Their expression has previously been analyzed in various bovine ...
Changes in the expression of Heat Shock Proteins in ovaries from bovines with cystic ovarian disease induced by ACTH
(Elsevier, 2013-12)
Cystic ovarian disease (COD), which is considered one of the most important causes of reproductive failure in dairy cattle, induces intraovarian changes in the expression of numerous genes. The purpose of this study was ...
Sex hormone binding globulin during an annual reproductive cycle in the hepatopancreas and ovary of pejerrey (Odontesthes bonariensis)
(Academic Press Inc Elsevier Science, 2019-02)
In the present study, we determined the hepatopancratic shbg transcript abundance and ovarian immunoreactive Shbg (ir-Shbg) localization in pejerrey females at different gonadal stages during an annual ovarian cycle. In ...
A dual death/survival role of autophagy in the adult ovary of Lagostomus maximus (Mammalia- Rodentia)
(Public Library of Science, 2020-05)
Follicular atresia is a cell death event that occurs in the great majority of follicles before ovulation in the mature mammalian ovary. Germ cell loss has been mainly associated to apoptosis although autophagy also seems ...
