title: PDGF-induces the glutathione-dependent enzyme PGH2/PGE2 isomerase in NIH3T3 and pEJ transformed fibroblasts.
abstract: Exposure of NIH3T3 and pEJ serum-starved cells to platelet derived growth factor results in a 16 fold increase in the glutathione-dependent enzyme prostaglandin H2/prostaglandin E2 isomerase activity (EC 5.3.99.3). The response is rapid as a detectable increase in NIH3T3 cells occurs after only 7 minutes of exposure to the growth factor. Only a mild increase in another microsomal glutathione-dependent enzyme, microsomal glutathione transferase (EC 2.5.1.18), was detected after a 2 hour exposure to the growth factor.
