Effect of VERU-111 on cell cycle arrest of PanCa (Panc-1 and AsPC-1) cells was analyzed by flow cytometric analysis. Briefly, approximately 70% confluent cells were synchronized by overnight incubation in FBS free media. Cells were treated with VERU-111 (0, 5, 10, and 20 nM) for 24 h, harvested, fixed overnight in ice-cold ethanol (70%) followed by incubation with RNAse and incubated with the DNA staining Propidium iodide (Sigma) for flow cytometry. Data regarding the number of cells in different phases of the cell cycle was analyzed by BD Accuri C6; Becton-Dickinson, Mountain View, CA.
