ART decreases COX-2 expression and prostaglandin E2 (PGE2) production in bladder cancer cells. T24 and RT4 cells were treated with different concentrations of ART, followed by real-time PCR (A) and Western blot analysis (B); The concentrations of PGE2 were detected in the supernatants of T24 and RT4 cells treated with different concentration of ART (C). * p < 0.05, compared to vehicle.
