| Additional info: | Prostaglandin F2(alpha) (PGF2(alpha)) is one of the five primary PGs derived enzymatically directly from the endoperoxide PGH2. It was initially discovered in seminal fluid, and to date the majority of the functional roles ascribed to it relate to fertility, pregnancy, and parturition. PGF2(alpha) is a potent luteolytic agent and is used to induce ovulation in domestic livestock. It is also a potent uterine stimulant, and is part of the cascade of myometrial stimulants which induce and sustain labor. PGF2(alpha) is rapidly metabolized to 13,14-dihydro-15-keto PGF2(alpha) in vivo, and the levels of this metabolite in both plasma and amniotic fluid are elevated during active labor in several different mammalian species. Like all of the primary PGs, PGF2(alpha). has a very short half-life in the general circulation. The plasma concentration of PGF2(alpha) in humans is <10 pg/ml, and probably no more than 1-2 pg/ml. PGF2(alpha) is rapidly metabolized by 15-hydroxy PG dehydrogenase and both .beta.- and .omega.-oxidation systems to a variety of polar metabolites. In primary cultures, the metabolism of PGF2(alpha) is much more limited, and it may collect in the supernatant medium to easily measured concentrations. Amnionic and placental tissue PGF2(alpha) content in the range from 100-250 ng/g of tissue has been reported. However, this study did not address the presence of isoprostanes and reported measurements using an unvalidated RIA method. A controlled GC- or LC-MS study of tissue PG content has not been reported. Tissue PG measurements in general are difficult to perform, vary widely, and are challenging to interpret. |
