In numerous animal species, increased prostaglandin output by intrauterine tissues occurs
in association with parturition. In the sheep, prostaglandin H synthase (PGHS) is particularly …

Increased prostaglandin production by tissues in the sheep uterus and placenta are thought
to be important for the onset of parturition. In the sheep placenta, this is most likely due to …

Prostaglandin H synthase (PGHS) activity within intrauterine tissues is considered to
catalyze a critical step in prostaglandin (PG) biosynthesis at parturition. In sheep, the …

Enhanced prostaglandin production and release by the placenta is an essential element in
the normal transition to labour in many animal species. In sheep, expression of …

Prostaglandin F2α (PGF2α) and PGE2 produced by the uterine tissues have long been
considered to be important during pregnancy for the regulation of blood flow (Carter, 1998) …

The aim of this study was to establish the gestational-and labour-associated variation in the
relative abundance of prostaglandin synthase-1 (PGHS-1) and prostaglandin synthase-2 …

We examined whether spontaneous parturition in sheep was associated with tissue-specific
changes in prostaglandin H2 synthase-2 (PGHS-2) expression and/or with altered …

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 …

Parturition in the ewe is preceded by an increase in the synthesis of prostaglandins (PGs) by
gestational tissues. To establish the uterine source of these PGs, placental cotyledons, fetal …

In this study, using gel electrophoresis and Western blotting, we have demonstrated that the
content of irPGHS in ovine placenta increases during late gestation prior to the onset of …
