Light microscope and transmission electron microscopy showed that SMMC-7721 cells induced by SAHA had undergone the restorational alteration in morphology and ultrastructure, which were different from those of nontreated cells but were similar to those of normal cells, and the changes were as follows: the cells turned to be flat and spread; the nucleo-cytoplasmic ratio lessened and nuclear shape became rather regular; the number of nucleolus reduced and its volume lessened; euchromatin increased while heterochromatin decreased in nucleus; in the cytoplasm, mitochondria grew in number with relatively consistent structure and well-developed mitochondria cristae; Golgi complex turned to be well-developed and typical; rough endoplasmic reticulum increased. Immunocytochemistry assay showed that the expression of AFP and PCNA were declined significantly. FCM analysis showed SAHA could arrest SMMC-7721 cells in G0/G1 phase, with an accumulation of the cells in G0/G1 phase while a decrease of cells in S phase. Semi-quantitative RT-PCR detection revealed that the expression of p21WAFl mRNA was upregulated remarkably in the cells treated with SAHA.
结果:倒置显微镜和透射电镜观察显示,经SAHA处理的细胞增殖速度显著减慢,细胞体积增大,细胞核较小,形状较为规则,核仁数量减少、体积变小,核内常染色质增多而异染色质减少,核质比例减小,细胞质内线粒体数量增多、线粒体嵴发达,高尔基体较为典型,粗糙型内质网增多,呈现出与正常上皮细胞相似的形态变化;MTT比色法测定结果显示不同浓度(2.5、5.0、7.5、10.0uM)SAHA对SMMC-7721细胞的增殖均有抑制作用,并有明显的剂量依赖和时间依赖关系;免疫细胞化学检测显示SAHA能显著降低PCNA和AFP在SMMC-7721细胞中的表达;流式细胞仪检测结果显示,SMMC-7721细胞经SAHA处理后,G0/G1期细胞明显增加,S期细胞则明显减少,细胞被阻滞于G0/G1期;RT-PCR检测结果表明,SAHA作用12h后SMMC-7721细胞中p21WAF1 mRNA的表达即有增加,24h后更为明显。

Our results indicate that 1 NSC606985, at nanomolar level, can effectively induce apoptosis in AML cells NB4 and U937 and significantly inhibit the proliferation without cell death in breakpoint cluster region–Abelson murine leukemia kinase-carrying leukemic K562 cells; 2 At such low concentrations, this agent also significantly inhibits the clonogenic activity of hematopoietic progenitors from patients with AML; 3 For apoptosis induction, NSC606985 rapidly induces the proteolytic activation of protein kinase Cδ with loss of mitochondrial transmembrane potential and caspase-3 activation; 4 Co-treatment with rottlerin, a PKCδ-specific inhibitor, completely blocks NSC606985-induced mitochondrial m loss and caspase-3 activation, while the
