Fig. 1. Esculetin inhibits proliferation of PC3, DU145, and LNCaP PCa cells. (A, B) The cell viability was measured by MTT test after esculetin treatments. PC3 cells were treated with various concentrations of esculetin (9.4–600 μM) for 24 to 72 hours. (C) PC3, DU145, and LNCaP cells were exposed to different concentrations of esculetin (25–600 μM) for 48 hours. Each column represents the mean ± SD. *P < 0.05 compared with untreated (Ut).
