Metabolite Identification
Common NameProstaglandin A2
DescriptionProduced by the seminal vessicals: Prostaglandins are a group of lipid compounds that are derived enzymatically from fattyacids. Technically a hormone, the prostanoid class of fatty acid derivatives is a subclass of eicosanoids. Prostaglandin A is a cyclopentenone and is an endogenous metabolite derived from arachidonic acid. Exhibits potent cellular anti-proliferative activity in vivo and in vitro. Excess PGA2 causes an accumulation in both S and G2/M, and a marked decrease in G1. As well there is an increase in DNA content preceeding the G0/G1 peak (indicative of apoptic body formation) mediated by changes in expression levels of Bax and Bcl-2. Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs) and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes) and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signaling pathways.
