| Description: | The murine monocyte/macrophage cell line J774 is grown in Dulbecco's modified Eagle's medium (DMEM), enriched with glutamine (2 mM), HEPES (25 mM), penicillin (100 ug/mL), streptomycin (100 ug/mL), 10% of fetal bovine serum (FBS) and 1.2% of sodium pyruvate. The cells are distributed in 24-well plates at a density of 2.5x105 cells/mL or in culture dishes with a diameter of 10 cm (1x107 cells/10 mL/dish) and kept for 2 hours at 37° C. in a CO2 (5%)/O2 (95%) atmosphere. Just before the experiments, the culture medium is replaced with fresh medium without FBS to avoid interference during the radio-immunological phase and the cells are stimulated as described below.Evaluation of COX-1 Activity.The cells are pretreated with the test compounds for 15 minutes and then incubated for 30 minutes with arachidonic acid (15x10-6 m). At the end of incubation the supernatants are collected for evaluating, by means of radio-immunological assays, the amount of PGE2 produced. |
