The following five reviews published in this volume summarize recent discoveries in this area: DNA Replication and Transcription in Mammalian Mitochondria, Mitochondrial-Nuclear Communications, Translocation of Proteins into Mitochondria, The Machines that Divide and Fuse Mitochondria, and Why Do We Still Have a Maternally Inherited Mitochondrial DNA?

这一卷发表的以下五篇综述总结了这个领域的最新发现：哺乳动物线粒体中的DNA复制和转录，线粒体-细胞核通信，蛋白质到线粒体的迁移，分离和融合线粒体的机制及为什么我们仍然有一个母系遗传的线粒体DNA？

So, the nucleocytoplasmic ratio decreased. 10^(-5)MATRA significantly suppressed the proliferation of os732 with only 39.5% cells when compared with untreated cells. Cells in G1 phase increased significantly, and the number of S phase decreased. Expressions of cy-clinD1, cycimD2 and CDK4 mRNA declined, especially cyclinD2 and CDK However, expressions of cyclinD3 and P21WAF1 mRNA changed little.

结果 ATRA作用后，OS732细胞胞浆展开，细胞核变小，核浆比例变小；瘤细胞生长减慢，细胞计数为正常对照组的39.5%； G0/G1期细胞明显增多，S期细胞减少，细胞阻滞于G0/G1期；CyclinD1、CyclinD2、CDK4mRNA表达均下降，尤以CylinD2、CDK4下降最明显，CyclinD3、P21WAF1mRNA未见明显改变。

It had fine horticultural characters and stable sterility inheritance according to Mendel's law controlled by a pare of nuclear recessive genes.

该两用系综合农艺性状优良，其不育性由细胞核内一对隐性基因控制，败育彻底，能够按照1：1育性分离比例稳定遗传。

This paper reports the ultrastructure of mesophyll cells of wheat seedlings in NaCl.

在含NaCl的培养液中培养小麦幼苗，3天后取样观察叶肉细胞，其超微结构基本正常，细胞核和细胞壁没有明显变化。

Under normal temperature,both Ca2+ and oxalate treatments could induce theexpression of sHSP in mesophyll and root cells.

常温下，在对照辣椒叶肉细胞和根尖分生细胞中，小分子量热激蛋白的表达量非常低或很难观察到；热胁迫下在细胞核、线粒体以及细胞质中增加。

The thickness and groundsubstance of cartilage in OA was thinning and uneven, and metachromatism could be seen.

正常软骨细胞的细胞核与细胞浆中有IGFⅡmRNA的表达。

The expression of proliferating cell nuclear antigen in each group was detected by immuno-histochemistry method. The cell cycle distribution was measured by flow cyto- metic analysis.

MTT法及免疫组织化学染色增生细胞核抗原法检测细胞生长活性，流式细胞仪测定细胞周期时相变化。

Using this method, the nucleus was completely eliminated and another was injected using the microscope and micromanipulator. Moreover, the efficiency of nuclear transplantation and survival rate of reconstructed embryos were greatly improved. Furthermore, it is very easy to manipulate and popularize in practice.

实验证明，用此方法可以在只有倒置显微镜和显微操作仪的条件下一次性快速完成去核和注核，大大提高了细胞核移植的效率和重构胚成活率；更重要的是该方法操作简单，新手可以很快掌握该技术，易于在实际工作中推广应用。

It was more possible that β-catenin could promote the mitosis and differentiation of stem cells.

结果发现，转染后的毛囊细胞核内β-catenin表达增高。
