In bovine females, 17β-estradiol (17β-E2) stimulates the synthesis of endometrial PGF2α,
however the mechanisms of this action are unknown. The aim of this study was to determine …

Abstract In cattle, 17β-estradiol (E2) is essential for triggering luteolysis via the synthesis of
prostaglandin F2α (PGF2α). We aimed to evaluate the effects of E2-treatment on day 15 of …

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 …

In cattle, luteolysis results from the pulsatile release of endometrial prostaglandin F2α
(PGF2α). Estradiol-17β (E2) and progesterone (P4) are involved in the regulation of …

The objective of the present study was to determine how low progesterone (P4) affects the
endometrial transcriptome, with specific emphasis on those changes that may impact …

Two experiments were conducted to examine the effect of estradiol-17β (E 2-17β) on content
of immunoreactive prostagladin F 2 α (PGF, ng) and total protein (TUP, mg) in uterine …

Background During female reproductive cycles, a rapid fall in circulating progesterone (P4)
levels is one of the earliest events that occur during induced luteolysis in mammals. In …

Progesterone (P4) decreases oxytocin (OT)-stimulated prostaglandin (PG) F2α, but not
PGE2 secretion from bovine endometrial cells and this effect is partly elicited via a non …

There is growing evidence to indicate that PGF (2alpha)-induced luteolysis involves altered
gene expression in the corpus luteum. Concentrations of mRNA encoding nine different …

In cattle, elevated concentrations of circulating progesterone (P4) in the immediate
postconception period are associated with advanced conceptus development, while low P4 …
