Effects of celecoxib on the PGE2 level of MCF-7 cells by ELISA. A: control group; B: 10 μmol/L celecoxib; C: 20 μmol/L celecoxib; D: 40 μmol/L celecoxib. PGE2 levels of MCF-7 cells were determined by ELISA after treated with 0-40 μmol/L celecoxib for 48 h. This assay was done triplicate. Values represent means ± standard deviations and were determined using the Student’s t-test. *P<0.05, ** P<0.01 vs. control.
