结果 细胞经顺铂处理后浓缩、深染、致密的染色质沿核膜下凝集、有凋亡小体形成。

When chromatin is reproduced, a stretch of DNA already associated with nucleosomes is replicated, giving rise to two daughter duplexes.

体外合成核小体要从考虑自由DNA和组蛋白的组装过程开始，但体内的核小体仅在DNA复制时形成。

Results: Compared with control group, apoptosis cells increased from 0.5%to 10%(some even to 15%) after 24,48 and 72 h action of -300,-500 and -1 000 V electrets. After action of -500 V PTFE electrets for 48-72 h, fibroblast cells showed characteristic morphological features of apoptosis. These features included chromatin aggregation, nuclear and cytoplasmic condensation and partition of cytoplasm and nucleus into membrane bound-vesicles.

结果：-300、-500和-1 000 V驻极体作用成纤维细胞24、48和72 h以后，与对照组相比，成纤维细胞的凋亡量从0.5％增至10％（部分可达15％）；驻极体作用成纤维细胞48～72 h，出现细胞凋亡特有的形态学特征，即：细胞异染色质边集，细胞裂解，可见凋亡小体。

NSCs existed in the occipital of cortex of different fetal age included middling round cells, NSCs had enations from 0 to 1. Nucli were larger than plasm. Each NSC had nucleoli from 2-4 and rarefaction chromatin. Most of NSCs distributed in three growth modes including crowd, cluster and clone, occasionally with a single growth mode among other nerve ceils.

NSCs呈明显的区域性分布，大部分NSCs以群状、簇状或数个细胞形成的小集落样生长方式存在，少数NSCs以单个形式存在于其他神经细胞中，各胎龄组NSCs在分布、形态、种类、生长方式等方面无明显差异。

The Lab is interested in both genome storage, compaction and transcriptional regulation in eucaryotes, and more specifically in the structure, function, and molecular modification of chromatin.

该实验室主要研究真核细胞基因组的存储、压缩以及转录调？？，尤其是染色质的结构、功能核分子修饰等。

Chromodomain is a conserved gene element and has been found in Eukaryon from yeast to mammal. It is involved in chromatin remodling and gene expression regulation.

染色质域是从酵母到哺乳动物的真核生物中普遍存在的一个保守的基因元件，参与染色质重组和基因表达调节。

Results After culturing with As 2O 3,PIEC present paste wall cells decrease,float,vacuolation,fat granule increase,and apoptotic features:i.e.cell membrane integrity,chromatin condensation,apoptotic body formation,etc.

为此我们采用猪髂动脉内皮细胞为对象，研究不同浓度As2 O3 对PIEC生长的影响，探讨介入放射学方法导入As2 O3 治疗实体瘤的作用机制。

The function of plant genomes depends on chromatin marks such as the methylation of DNA and the post-translational modification of histones.

植物基因组的功能依赖于染色质标记，诸如DNA的甲基化和组蛋白的转录后修饰。

Covalent modification of histones on chromatin is a dynamic mechanism by which various nuclear processes are regulated.

染色质上组蛋白的共价修饰是一个动态的机制，多种细胞核过程通过该机制被调控。

Studies on many aspects show that there are four main reasons which cause the epigenetic effects;the methylation of DNA,the acetylation of histones,the change of chromatin structure and the alteration of protein configuration.

多方面的研究表明，导致后生效应的可能原因主要有四个方面：DNA的甲基化、组蛋白的乙酰化、染色质结构背景的改变和蛋白质构型的变化。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
