Expression of the gene for prostaglandin synthase (PGS) was examined in whole
endometrial tissue derived from ewes during the oestrous cycle (Days 4–14), on Day 15 of …

Prostaglandin (PG) synthase has been localized by immunocytochemistry within the ovine
uterus throughout the oestrous cycle and in early pregnancy. On Day 4 of the cycle, PG …

In experiment 1, 20 ovariectomized ewes were used to determine how progesterone and
estradiol interact to regulate endometrial concentration and activity of prostaglandin …

Luteolysis in domestic species is mediated by the release of luteolytic pulses of
prostaglandin (PG) F2α by the uterus at the end of diestrus, which must be suppressed by …

Prostaglandins (PGs) are important regulators of reproductive functions. In ruminants,
interferon (IFN)-τ is the embryonic signal responsible for recognition of pregnancy. This is …

We hypothesised that different endocrine profiles associated with pre-ovulatory follicle (POF)
size would impact on uterine prostanoid pathways and thereby modulate the histotroph …

Endometrial prostaglandins (PGs) and the PGE2/PGF2α ratio play an important role in
regulating the estrous cycle and establishment of pregnancy. The enzymes downstream of …

Ovine endometrium showed transient expression of high concentrations of the inducible
isoform of cyclooxygenase, cyclooxygenase 2 (COX-2), whereas the constitutive isoform …

Contents Sex steroids in synergy with prostaglandins (PG) are involved in the regulation of
cyclic ovarian function. In this study, we investigated the mRNA expression of three genes …

Prostaglandins (PG) have primary functions in the reproductive tract, however, the
mechanism of regulation of PG secretion in the endometrium is unclear. Estrogen as a …
