Figure 10From: Effects of valproic acid on the cell cycle and apoptosis through acetylation of histone and tubulin in a scirrhous gastric cancer cell lineEffects of VPA on apoptosis in the xenograft model. Shrunken tumor cells showed positive reactivity in TUNEL assay. Apoptotic index of the VPA-treated group was significantly higher than that of the control group.
