1 HUVEC treated with aspirin lost their capacity to generate PGs but recovery occurred after 3- or 6-h induction of Cox-2 with phorbol ester or IL-1alpha. Aspirin prostaglandin-endoperoxide synthase 2 Homo sapiens
2 Enzyme activity of the newly synthesized Cox-2 in aspirin-treated cells, evaluated after immunoprecipitation, was similar to untreated cells but after 18 h of cell stimulation only 50-60% recovery of Cox-1 was observed. Aspirin prostaglandin-endoperoxide synthase 2 Homo sapiens
3 However, in acetylsalicylic acid-treated cells, after 6-h stimulation with IL-1alpha, newly synthesized Cox-2 produced less TXB2 than 6-keto-PGF1alpha compared to untreated cells. Aspirin prostaglandin-endoperoxide synthase 2 Homo sapiens
