Prostaglandin E2 synthesis and eicosanoid biosynthetic enzyme activities (arachidonyl CoA synthetase, cyclooxygenase and phospholipase A2) were measured in dermal fibroblasts from patients with metabolic disorders of peroxisomal origin and compared to those from normal subjects and patients with other metabolic disorders of lipid metabolism. Basal- as well as interleukin 1-stimulated prostaglandin E2 syntheses were higher in fibroblasts from patients with X-linked adrenoleukodystrophy, the Zellweger cerebrohepatorenal syndrome and rhizomelic chondrodysplasia punctata than in normals. Basal cyclooxygenase and phospholipase A2 activities were elevated in most of the peroxisomal disease cells. Cells from patients with adrenomyeloneuropathy, however, had significantly lower cytokine-stimulated cyclooxygenase and phospholipase A2 activities than normals, as well as lower prostaglandin E2 synthesis in response to interleukin 1. The peroxisomal disease lines exhibited dose-response curves to interleukin 1 similar to controls. Receptor-binding analysis indicated that cells from patients with rhizomelic chondrodysplasia punctata expressed 5-times fewer interleukin 1 receptors than normals and the other disease lines. Exaggerated arachidonic acid metabolism in response to interleukin 1 suggests that cells from patients with peroxisomal enzyme defects may be useful in elucidating pathways for arachidonate release and eicosanoid synthesis.
