Involvement of phosphatidate phosphohydrolase in arachidonic acid mobilization in human amnionic WISH cells.
Prostaglandins are known to play a central role in the initiation of labor in humans, and amnionic cells constitute a major source of these compounds. Prostaglandin synthesis and release by amnion cells in response to hormones and ligands takes place after a characteristic 4-5 h lag. However, we report herein that free arachidonic acid (AA), the metabolic precursor of prostaglandins, can be ind...
متن کاملPossible Involvement of Hepatic Phosphatidate Phosphohydrolase in the Mechanisms of Actions of Certain Antilipemic Drugs in Rats
The effects of therapeutic doses of dillsun, garsin, antum and statins on rat liver cytosolic phosphatidate phosphohydrolase (PAP) activity, a key enzyme in triacylglycerol synthesis, and on serum and liver lipids were examined. Lovastatin and simvastatin both stimulated the enzyme activity by 29% and 43%, respectively. The stimulatory effects were dose-dependent and accompanied by the decline ...
متن کاملThe measurement of phosphatidate phosphohydrolase in human amniotic fluid.
Phosphatidate phosphohydrolase (EC 3.1.3.4) activity can be found in late gestational human amniotic fluid and is thought to originate in type II alveolar cells of the fetal lungs where it plays an important role in lung surfactant synthesis. In the present study, phosphatidate phosphohydrolase activity was detected and characterized in a 105 000 X g pellet of amniotic fluid using either [32P]p...

متن کاملEvaluating the effect of arachidonic acid and eicosapentaenoic acid on induction of adipogenesis in human adipose-derived stem cells
Objective(s): Adipose tissue is one of the most important endocrine organs that liberates many metabolic mediators such as hormones, cytokines, and chemokines. Different types of fatty acids have key roles in adipogenesis. The aim of this study was to evaluate the effects of two essential fatty acids, including Arachidonic acid (AA) and Eicosapentaenoic acid (EPA), on ...
