Prostaglandin F2α Receptor-Dependent Regulation of Prostaglandin Transport

Molecular Pharmacology, 2001
Prostaglandin (PG) F(2alpha) may act on its G protein-coupled receptor (FP) or be imported intracellularly via a transporter, which has high affinity for PGF(2alpha) and PGE(2), but not prostacyclin (PGI(2)). In cells overexpressing the epitope-tagged FP together with the human prostaglandin transporter (hPGT), stimulation of the FP with PGF(2alpha) (1

Roles of Prostaglandin F Synthase

2001
Prostaglandin (PG) F2 is widely distributed in various organs, and exhibits various biological actions such as smooth muscle contraction of uterus [1], bronchus [2], and trachea [3], the initiation of parturition [4], and pain transmission [5]. PGF synthase (PGFS) is a dual function enzyme, which catalyzes the reduction of not only PGD2 but also PGH2 ...

Specific reduction of E prostaglandins to F.alpha. prostaglandins and prostaglandin E2 to prostaglandin E1

Journal of the American Chemical Society, 1971
This is an explanation of 2 highly specific reductive processes for the interconversion of primary PGs (prostaglandins). The laboratory procedures are described in detail and the chemical structures of substances involved in the process are diagrammed. A stereospecific reduction of PGE to PGFalpha is described.

Possible role of prostaglandin F in blastocyst implantation

Prostaglandins, 1986
The synthesis and release of Prostaglandin F (PGF) by the rabbit blastocyst and endometrium were investigated on Day 6 and Day 7, using radioimmunoassay, autoradiography and conversion experiments. The following results were obtained: The content of PGF in the blastocyst increased significantly (P less than 0.01) from Day 6 to Day 7. The content of PGF

The distribution of prostaglandins A, E, and F in the human kidney

Prostaglandins, 1974
Abstract Using recently developed radioimmunoassay techniques, prostaglandin concentrations were measured in two human cadaver kidneys which had been processed for transplantation but for which no recipient patients could be obtained. Portions of cortex, medulla, papilla, and ureter were obtained from each kidney.

Prostaglandin F _2α , ‘the' Luteolysin in the Mammal?

Gynecologic and Obstetric Investigation, 2010
Part. I: Prostaglandin F₂_Α (PGF_2Α) was shown to be ‘the’ luteolysin in the ewe on the following criteria: (1) Hysterectomy and/or separation of the uterine horn from the ovary bearing a corpus luteum led to prolongation of the oestrous cycle, (2) PGF_2Αshortened

Identification of prostaglandin F-producing cells in the liver

Histochemistry and Cell Biology, 1999
Prostaglandin (PG) F synthase forms PGF(2alpha) and 9alpha, 11beta-PGF2 from PGH2 and PGD2, respectively. PGH2 is synthesized from arachidonic acid by cyclooxygenase (COX) and then metabolized to various PGs and thromboxane by specific enzymes. PGD2 is synthesized from PGH2 by PGD synthase.

Relationship between Prostaglandin F and Steroids in Human Peripheral Venous Plasma and Concentration of Prostaglandin F in Corpus Luteum

Asia-Oceania Journal of Obstetrics and Gynaecology, 1984
AbstractConcentrations of prostaglandin F and steroids in plasma and in corpus luteum (CL) were studied by radioimmunoassay during the luteal phase of the menstrual cycle in thirteen normal women.The average concentration of PGF in corpus luteum was 4.19 ± 1.59 ng/g (mean ± SE) (ranging from 0.03 to 20.5 ng/g) and in plasma was 208.1 ± 34.7 pg/ml ...

CHANGES IN PROSTAGLANDIN F AND 13,14‐DIHYDRO‐15‐KETO‐PROSTAGLANDIN F CONCENTRATIONS IN AMNIOTIC FLUID AT THE ONSET OF AND DURING LABOUR

BJOG: An International Journal of Obstetrics & Gynaecology, 1977
SummaryConcentrations of prostaglandin F (PGF) and its major circulating metabolite 13,14‐dihydro‐15‐keto‐PGF (PGFM) have been measured in amniotic fluid during spontaneous labour at term. Levels of both PGF and PGFM were significantly higher during early spontaneous labour, at a cervical dilatation of less than 4 cm, than before the onset of labour ...
