Time-course of the tumor growth in mice transplanted with Kasumi-1 cells. The mice were intraperitoneally administered 0.2 ml VPA (500 mg/kg body weight) or 0.2 ml saline daily for two weeks. The tumor volumes (TV) were measured every three days. The data are shown as the mean ± standard deviation (n=6 for the control and VPA groups). VPA, valproic acid.
