Modulation of the epidermal growth factor mitogenic response by metabolites of linoleic and arachidonic acid in Syrian hamster embryo fibroblasts. Differential effects in tumor suppressor gene (+) and (-) phenotypes.

Abstract excerpt

Specific metabolites of arachidonic and linoleic acid have been proposed as serving a regulatory function in growth factor signal transduction in fibroblasts. In studies with Syrian hamster embryo (SHE) fibroblasts, we found lipoxygenase inhibitors to be potent blockers of epidermal growth factor (EGF)-dependent mitogenesis. Analytical chemical characterization of arachidonic and linoleic acid metabolism in SHE...
