We explored a potential mechanism linking placental prostaglandins (PGs) with a fall in
plasma progesterone and increased expression of uterine activation proteins in the mouse …

Since both prostaglandin (PG) F 2α and corticosteroids are elevated in mammals before the
onset of parturition, we studied the effect of the synthetic corticosteroid dexamethasone on …

Abstract Prostaglandin G/H synthase (PGHS) is a key rate-limiting enzyme in the
prostaglandin biosynthetic pathway, and prostaglandins play a central role in the control of …

Porcine trophoblast attachment to the uterine surface is associated with increased
conceptus and endometrial production of prostaglandins. Conceptus secretion of estrogen …

Abstract PG endoperoxide H synthase-2 (PGHS-2) messenger RNA (mRNA) and protein
levels are increased dramatically in ovine myometrium and endometrium during both …

Recent identification of a second, inducible form of prostaglandin H synthase (PGHS-2) led
to the hypothesis that constitutively expressed PGHS (PGHS-1) is involved in the …

Fetal glucocorticoid-induced premature labor in sheep is an established model of premature
labor. However, the pathways by which fetal cortisol triggers subsequent maternal endocrine …

Expression of cyclooxygenase 2 (COX2, now known as PTGS2), prostaglandin E2 synthase
(PTGES, PGES), and prostaglandin F2α synthase (PGFS), of the respective receptors …

The high activity of 15-hydroxyprostaglandin dehydrogenase (PGDH) which catalyzes the
first step in prostaglandin metabolism has been demonstrated in the human placenta. To …

The present study was conducted to evaluate the effect of the conceptus on uterine
prostaglandin-F2α (PGF2α) and prostaglandin-E2 (PGE2) release and the expression of …
