title: Prostaglandin E2 production in 3T3 cells transformed by polyoma virus raises the intracellular adenosine 3':5'-monophosphate levels.
abstract: High cellular adenosine 3':5'-monophosphate (cyclic AMP) were found in a polyoma-virus-transformed 3T3 fibroblast line, which produces comparatively high prostaglandin E2 concentrations. Prostaglandin E2 and cyclic AMP increased with time during 6 days of growth. Both effects were prevented by three different cyclo-oxygenase inhibitors. Addition of prostaglandin E2, at a concentration which would been synthesized in the absence of inhibitor, reversed the effect of indomethacin, one of the cyclo-oxygenase inhibitors, on cyclic AMP. It is concluded that endogenous prostaglandin E2 production in these transformed cells influences their cellular cyclic AMP levels.
