Figure 2From: Effects of valproic acid on the cell cycle and apoptosis through acetylation of histone and tubulin in a scirrhous gastric cancer cell lineImmunostaining of HDAC1 and HDAC2 in OCUM-2MD3 cells. Both HDAC1 and HDAC2 were expressed mainly in nuclei of tumor cells. Expression of HDAC2 was observed characteristically in tumor cells in the mitotic period (arrows). (a) HDAC1, (b) HDAC2.
