The role of Group IVA cytosolic phospholipase A2 alpha (cPLA2 alpha) in PGE2 production was investigated by comparing lung fibroblasts from wild-type and cPLA2 alpha-deficient mice. Arachidonic acid release from wild-type mouse lung fibroblasts (MLF+/+) was stimulated by serum, A23187 plus phorbol-myristate acetate (PMA), and lysophosphatidic acid (LPA) plus platelet-derived growth factor, but was > or = 80% lower from cPLA2 alpha-deficient MLF (MLF-/-). Transforming growth factor-beta increased cyclooxygenase-2 (COX2) expression to similar levels in MLF+/+ and MLF-/-, but MLF+/+ produced an order of magnitude more PGE2 than MLF-/-in response to A23187/PMA or platelet-derived growth factor/LPA. MLF+/+ synthesized less collagen than MLF-/-, supporting a role for PGE2 in suppressing collagen production. An SV40 immortalized line developed from MLF+/+ released arachidonic acid and expressed COX2 to levels similar to those of primary fibroblasts but produced 30-fold lower amounts of PGE2. Unlike primary fibroblasts, immortalized cells were deficient in microsomal PGE synthase (mPGES) but expressed slightly higher levels of cytosolic PGES. The results demonstrate a primary role for cPLA2 alpha in providing arachidonic acid for PGE2 production in mouse lung fibroblasts and support a role for this pathway in regulating collagen production."xsd:string |
