PtPT treatment induced G2/M cell cycle arrest in ovarian cancer cells. a A2780 and SKOV3 cells were treated with 4–8 μM PtPT for 24 h and subsequent to PI staining and flow cytometry analysis. Representative images were shown. b Graphs of the analysis were shown. c Proteins extracts from A2780 and SKOV3 cells exposed to indicating concentrations of PtPT were subjected to Western blot analysis by using antibodies against Cdc2 and Cyclin B1. GAPDH was used as a loading control
