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

Prostaglandin E2 (PGE2) is shown to be essential for female reproduction. Cyclooxygenase
(COX) is a rate-limiting enzyme in prostaglandin synthesis from arachidonic acid and exists …

The ovine cervix relaxes at estrus allowing easier entry of spermatozoa into the uterus. The
mechanism responsible for this relaxation is not fully elucidated and we hypothesized that …

Contents Cyclooxygenase (COX) is the rate‐limiting enzyme that catalyses the initial step in
prostaglandins (PGs) production. In the present studies, endometrial COX‐1 and COX‐2 …

Vehicle or 8 or 16 mg of PGF 2α per 58 kg body weight was given intramuscularly to intact,
hysterectomized or ovariectomized 90–100 day pregnant ewes in three separate …

Prostaglandins are involved in mediating several important processes in mammalian
reproduction, including the initiation of parturition. In the present study, we examined the …

Prostaglandin (PGE) 2 is the most common prostanoid and plays an important role in female
reproduction. The aim of this study was to examine the expression and regulation of …

Parturition in the sheep is preceded by an increase in the synthesis of prostaglandins by
intrauterine tissues. Prostaglandin G/H synthase (PGHS) is the central enzyme involved in …

Prostaglandins (PGs) play a pivotal role in luteolysis, maternal recognition of pregnancy,
and implantation. In many species, including pigs, both conceptus (embryo and associated …

In sheep, the trophectoderm of the elongating conceptus secretes interferon tau (IFNT) and
prostaglandins (PGE2, PGF2alpha, PGI2). The PGs are derived from PG synthase 2 …
