Angiotensin II (Ang II) activates cytosolic phospholipase A2α and releases arachidonic acid (AA) from tissue phospholipids. AA metabolites mediate or modulate one or more renocardiovascular effects of this peptide and have been implicated in hypertension. Since AA release is the rate limiting step in eicosanoid production, it is possible that cPLA2α might play a central role in the development of Ang II-induced hypertension. To test this hypothesis, we investigated the effect of Ang II infusion for 13 days by micro-osmotic pumps (700 ng/kg/min), on systolic blood pressure and associated pathophysiological changes in wild type (cPLA2α+/+) and cPLA2α-/- mice. Ang II …
