Sex Steroid-Mediated Control of Oviductal Function in Cattle
Biology, 2018 In cattle, the oviduct is a tubular organ that connects the ovary and the uterus. The oviduct lumen stages a dynamic set of cellular and molecular interactions to fulfill the noble role of generating a new individual. Specific anatomical niches along the

PLoS ONE, 2016 Sperm are allogenic to the female genital tract; however, oviducts provide optimal conditions for survival and capacitation of these non-self cells until fertilization.

Aging Cell, EarlyView.Multi‐ciliated cells in the infundibulum and ampulla (INF/AMP) epithelium are vacuolated in aging. Unique cellular susceptibility of the INF/AMP epithelial population and aging‐associated decline in ovarian artery circulation, which supports the ovary and INF/AMP, contribute to this region‐specific vacuolation phenotype, as a consequence of a mildly ...

The octopamine receptor OAMB mediates ovulation via Ca2+/calmodulin-dependent protein kinase II in the Drosophila oviduct epithelium. [PDF]
PLoS ONE, 2009 Ovulation is an essential physiological process in sexual reproduction; however, the underlying cellular mechanisms are poorly understood. We have previously shown that OAMB, a Drosophila G-protein-coupled receptor for octopamine (the insect counterpart ...

Biosynthesis and expression of zona pellucida glycoproteins in mammals [PDF]
, 2001 The zona pellucida (ZP) is an extracellular matrix surrounding the oocyte and the early embryo that exerts several important functions during fertilization and early embryonic development.

Annals of Biomedical Engineering, 2016 The oviduct was long considered a largely passive conduit for gametes and embryos. However, an increasing number of studies into oviduct physiology have demonstrated that it specifically and significantly influences gamete interaction, fertilization and ...

Aging Cell, EarlyView.Autophagy regulates ovarian reserve, with Cathepsin B playing a critical role in aging. Inhibition of Cathepsin B increases follicle count, enhances IGF1R–AKT–mTOR signaling and improves mitochondrial function without compromising fertility. This conserved mechanism suggests potential therapeutic strategies to delay ovarian aging and sustain fertility,

GENERAL HISTOMORPHOLOGY AND DEVELOPMENTAL CHANGES IN THE OVIDUCT OF KUTTANAD DUCKS (Anas platyrhynchos domesticus) [PDF]
Journal of Veterinary and Animal Sciences, 2010 Postnatal developmental pattern of the oviduct in Kuttanad ducks was investigated using 78 ducklings from day-old to 24 weeks of age. The material was collected at fortnightly intervals from six birds in each group.

Inflammation is a key contributor to ovarian cancer cell seeding. [PDF]
, 2018 The incidence of ovarian cancer dramatically increases in early menopause but the factors contributing to cancer onset are unclear. Most ovarian cancers originate in the fallopian tube with subsequent implantation of malignant cells into the ovary ...

Spatial differences in gene expression in the bovine oviduct.
Reproduction, 2016 The aim of this study was to compare the transcriptome of the oviductal isthmus of pregnant heifers with that of cyclic heifers as well as to investigate spatial differences between the transcriptome of the isthmus and ampulla of the oviduct in pregnant ...
