Disease relevance of PLA2G4A

 

High impact information on PLA2G4A

  • These findings are consistent with the hypothesis that homologous up-regulation of MADR2 in granulosa cells may be an important determinant in its follicular stage-specific responsiveness to TGFbeta and possibly in the suppression of cPLA2 gene transcription by the growth factor [2].
  • The influence of TGFbeta in vitro on their expression was assessed, particularly in the context of TGFbeta-induced down-regulation of cytosolic phospholipase A2 (cPLA2), a key enzyme in the biosynthesis of eicosanoids [2].
  • Treatment of these cells with TGF alpha caused a shift from an electrophoretically fast-migrating to slow-migrating protein, a phenomenon sensitive to inhibitors of serine/threonine kinase as well as mitogen-activated protein (MAP) kinase pathways and indicative of phosphorylation and activation of cPLA2 [3].
  • Cytosolic PLA2 (cPLA2), a newly identified member of the PLA2 family, is distinct from the well-characterized, secreted 14-kDa group I and II PLA2 in that cPLA2 selectively cleaves arachidonic acid-containing phospholipids at the sn-2 position [3].
  • In the vitamin E-deficient cerebellum the enzyme activity of cytosolic phospholipase A2 was increased [4].
