W7 was added when the cells entered anaphase, we found that although some cells had elongated, the distribution patternof CaM at central spindle was normal, and it seemed that a cleavage furrow would possibly form soon, however, these cells stopped cytokinesis at this stage, no furrow ingression followed.

本实验中我们还观察到在胞质分裂后期，CaM与Y一微管蛋白共分布于中体两端。W7处理同步化在胞质分裂后期的细胞，不但使中体解聚发生延迟，而且抑制了Y一微管蛋白与中体的解离。

SCAP(SREBP cleavage-activating protein) appears to be a central regulator of cholesterol synthesis and intake in animal cells.

SREBP裂解激活蛋白(SREBP cleavage－activating protein，SCAP)是哺乳动物脂质合成和摄入的中心调节因子。

When electric fusion method was used for nuclear transfer, the fusion rate (46. 0%), cleavage rate (53. 9%) and blastocyte development rate (10.9%) of adult ear fibroblasts were significantly lower than that of fetal fibroblasts (64. 5%, 70.1%, 21. 6% respectively), fetal skin cells (71. 5%, 70.8%, 22. 1% respectively) and ovary granulosa cells (88. 2%, 79. 1%, 25. 5% respectively). There was no significant difference among other donor cells in the cleavage and blastocyst development rate of resconstituted embryos.

当用电融合法进行核移植时，成体耳部成纤维细胞的融合率（46.0％），卵裂率（53.9％）和囊胚发育率（10.9％）均显著低于胎儿成纤维细胞（64.5％，70.1％和21.6％），胎儿皮肤细胞（71.5％，70.8％和22.1％），以及卵巢颗粒细胞（88.2％，79.1％和25.5％）；另外三种细胞间的卵裂率，囊胚发育率无显著差异，但卵巢颗粒细胞的融合率显著高于胎儿成纤维细胞和胎儿皮肤细胞（88.2％vs 64.4％，71.5％，P＜0.05）。

The result is consistent with previous studies. Whereas, tapetal cells of sterile anthers were disintegrated since tetrad cells were disjoined, indicating that disintegration of tapetal cells is earlier occurred in sterile anther than that in fertile anther. DNA ladder revealed that the cleavage of nuclear DNA into oligonucleosome-sized fragments to

结果表明，在花粉母细胞减数分裂后的四分体解离时期，不育花药的绒粘层细胞较可育花药提前开始裂解；在不育系S-Mo17rf3rf3花药和花粉S-(rf3)中均明显出现PCD过程的DNA片段化以及线粒体细胞色素C外渗的现象，证明了玉米CMS-S的花粉败育与花药绒粘层细胞的提前凋亡和小孢子细胞的细胞程序性死亡有关。

Embryo cells display a synchron cleavage rhythm during the cleavage stage, there is almost no gene transactivation, which is regulate and operated by the mRNAs and protein of oocyte.

卵裂阶段的胚胎细胞呈现同步化的分裂节律，鲜有基因转录活动，其发育由源自卵母细胞发生期间合成的蛋白质和mRNAs调控。

At present time people has found that various oxidants exist in injured cells, including peroxide and other free radical (eg: peroxide anion and hydroxide radical ion); these ROS also exist in abnormal cells arose from cell cleavage block and cell function loss.

目前已经发现，损伤的细胞中含有较多的各类氧化物，包括过氧化氢以及其它自由基(例如过氧化物阴离子和氢氧根离子)；在因细胞分裂阻断以及细胞功能丧失所引起的异常细胞中也含有这些活性氧类物质。

It also reported that cells treated with edelfosine came through the whole cell cycle without nuclei cleavage, and cells were blocked in G_0/G_1 and subsequent formation of quadplex or octploid nuclei. However, the mechanism still is unknown that edelfosine inhibits cytokinesis.

也有报告指出，依地福新处理过的细胞能经历完全的细胞周期，但不能进行分裂，使细胞聚集在G_0／G_1期，形成四倍体或八倍体细胞。

Fluorescence staining of cell framework and nuclei were conducted, the result of which revealed that the transfected cells displayed disorder in cell skeleton, shrinkage and cleavage in nuclei. It was illuminated that chromosome DNA occurred cleavage and fragment since the result of TUNEL detection was positive. The transfected cells also displayed more typical apoptotic character, including exposure of phosphatidylserine in the plasma membrane by Annexin V staining detection, shrinkage nuclei, chromatin condensation, plasma membrane blebbing and chromatin breakage fragments by electron microscopy analyses.

细胞骨架和细胞核染色结果表明，AIF基因转染细胞呈现细胞骨架的紊乱、细胞核固缩、分裂等变化；TUNEL检测呈阳性，说明有染色体DNA出现断裂；Annexin V染色检测到转染细胞出现胞膜磷脂酰丝氨酸的暴露；电镜观察的结果显示，转染目的基因组细胞呈现细胞膜出泡、细胞核固缩、染色体凝集和断裂等典型的凋亡细胞特征。

Results As shown in Western blot analysis, the presence of microsomes did not alter the molecular weight of TM-TNF , but it did result in the cleavage of the IL-2 signal peptide from S-TNFm,suggesting that the leader sequence of TNF might differ from the signal peptide of typical secretory protein in that it seemed not to have undergone cleavage during translation in the rough-faced endoplasmic reticulum. Further enzymatic analysis revealed that TM-TNF was converted into S-TNF through the effect of certain metalloproteinase. Conclusions These results suggest that the mechanisms of TNF-α production may be as follows: Activation of TNF-α producing cells by LPS leads to augmented transcription/translation of TNF-α gene, resulting firstly

实验结果提示17×103 S-TNF产生机制可能是：TNF产生细胞经LPS等激活后，导致TNF基因转录翻译增加，首先形成26×103 TNF，并借助其信号肽疏水氨基酸部分将之&锚定&在细胞膜，成为跨膜型TNF，介导细胞与细胞之间的生物学效应；在某些蛋白酶作用下，可将mTNF的&信号肽&切除，产生17×103分泌型TNF，释放至体液中，在局部或全身发挥作用。
