Progesterone receptors: Their localization, binding activity and expression in the pig oviduct during follicular and luteal phases
(Elsevier Science Inc, 2005-01)
Estrogens (E) and progesterone (P) are known to require their respective steroid receptors in order to exert structural and functional effects on the oviduct. Cyclic changes in progesterone receptor (PR) localization in ...
Progesterone (PR), Oestrogen (ER-alpha and ER-beta) and Oxytocin (OTR) Gene Expression in the Oviduct and Uterus of Pregnant and Non-pregnant Bitches
(Wiley-Blackwell, 2012-12-01)
Contents The aim was to assess hormone receptor gene expression in the oviduct and uterus during canine pregnancy. Nineteen pregnant bitches divided into four groups were ovariohysterectomized (OVH) at either day 8, 12, ...

Can the antral follicular count modulate the gene expression of bovine oviducts in Aberdeen angus and nelore heifers?
(2018-08-01)
The number of visible ovarian antral follicles (antral follicle count—AFC) is repeatable in bovine individuals, but highly variable between animals, and with differences between Bos taurus and Bos indicus breeds. Several ...
Equine chorionic gonadotropin increases estradiol levels in the bovine oviduct and drives the transcription of genes related to fertilization in superstimulated cows
(Wiley-Blackwell, 2019-07-29)
In the bovine oviduct, estradiol (E2) stimulates secretion and cell proliferation, whereas progesterone (P4) suppresses them. In this study, we have evaluated the effect of two superstimulatory protocols (follicle-stimulating ...
Structural analysis of toad oviductal mucosa in relation to jelly components secretion throughout the reproductive cycle
(Cambridge University Press, 2012-11)
Summary In amphibians, the components of the jelly coats that surround the oocytes at the time of fertilization and coordinate gamete interaction are secreted by the oviduct. We analysed the histological variations ...
Expression profiles of the progesterone receptor, cyclooxygenase-2, growth differentiation factor 9, and bone morphogenetic protein 15 transcripts in the canine oviducts during the oestrous cycle
(MDPI, 2021)
The oestrous cycle in canines is specifically more extended than that in other mammals. This implies that the oocytes do not reach maturity within the ovarian follicle but undergo final maturation in the oviducts. Besides ...
Nitric oxide inhibits prostanoid synthesis in the rat oviduct
(Elsevier, 2000-04)
We have studied the effect of nitric oxide (NO) on the production of arachidonic acid ([14C]-AA) metabolites in the rat oviduct. The basal synthesis of eicosanoids was measured by the conversion of ([14C]-AA) to the different ...
