细胞核

A lot of organelles such as mitochondria, rough endoplasmic reticula and Golgi bodies were observed in fiber cell. Then, double karyotheca disappeared, and the organelles disintegrated. Multivesicular bodies appeared in fiber cytoplasm. With the further development of fiber, fiber wall underwent continual thickening with aging, and polylaminate structure gradually appeared. While the agglutinated nucleus, transfer vesicles, plasma membrane and plasmodesmata still presented.

研究发现，次生壁形成早期，细胞核具有双层核膜，染色质凝聚，可见大量的线粒体、粗面内质网和高尔基体等细胞器存在于纤维细胞中；随后，双层核膜消失，细胞器将逐渐解体，多泡体开始出现在纤维细胞的细胞质；随着年龄的增加，纤维细胞壁逐渐增厚，并出现多层结构现象，而运输小泡、细胞膜、胞间连丝和凝聚的染色质将持续存在。

The dense retrogradely labelled cell bodies were found in medial magnocellular nucleus of the anterior ne...

在端脑新纹状体前部的大细胞核内侧部、中部的界面核、尾中部的端脑听区、丘脑uvaeformis核及脑桥蓝斑见到大量逆行标记细胞。

However, the recent discoveries are overturning the traditional opinions. Nuclear-born tRNA can be exported out of nucleus, while cytoplasmic-residing tRNA can also be retrogradely transport into nucleus.

然而，最近的研究成果在颠覆传统观念，tRNA不但能被转运出核，还能被逆向转运入核。2008年，新概念&tRNA核质动态分布&(tRNA nuclear-cytoplasmic dynamics)被提出，取代tRNA核质运输，描述tRNA在细胞核、质间的流动。

Purpose : To explore the etiologic role of HPV infection in sophageal carcinoma , the association of HPV-16 E6 with the nuclear mat rix of carcinoma cells was investigated.

目的： 观察HPV-16 E6 和食管癌细胞核基质的关系，以探讨HPV 感染在食管癌变中的作用。

Our data are showed that apoptosis parameters including DNA fragmentation, nuclear morphological change and sub-G1 fraction, appeared after 24 h by 5 μM rottlerin treatment. Furthermore, rottlerin caused a decrease in 72% of ODC protein expression and an increase in threonine, rather than serine and tyrosine dephosphorylation on ODC enzyme compared with the control after incubation for 10 h. To determine whether ODC could down-regulate rottlerin-induced apoptosis, HL60 cells were stably transfected with ODC cDNA. HL60-ODC cells exhibited a 2.5-fold increase in ODC protein compared with vector only (HL60-pcDNA3) or HL60 cells.

在我们筛选天然化合物实验中，发现rottlerin抑制鸟胺酸去羧化活性最具成效，之前的研究人员已知蛋白激Cd调节鸟胺酸去羧化的活性，因此在人类白血病HL60细胞处理rottlerin的实验中发现加入rottlerin二十四小时后，细胞进行计划性死亡，并可侦测到DNA片段、细胞核浓缩及sub-G1提增；而细胞处理药物十小时后与控制组细胞比较，观察到鸟胺酸去羧化的蛋白表现与活性下降50﹪以上；除此以外，测定鸟胺酸去羧化去磷酸化的情况，发现於酥胺酸位置有显著差异，而丝胺酸和酪胺酸位置并无差异。

1Micron We are inside the ruffly lymphocyte, only to face another surface, a protective membrane within the cell that encloses its nucleus.

1微米 现在我们进入了这个皱皮的淋巴细胞中，但仅仅是在另一个表层上，这是细胞里一层保护性的膜，包囊了细胞核。

Spermatogenesis education isthe seminal vesicle for the same spermatocyst, the size of the nucleus is very similar tochromosomal changes, and the developmental level coincide.

拟黑多刺蚁精子发生是以育精囊为单位进行的，同一育精囊的生精细胞形态、大小以及细胞核内染色体变化极其相似，发育水平比较一致。

They are required for splicing of most introns.

是由RNA和蛋白质在细胞核中组成的大分子，在大多数内含子的剪接中都需要。

AIM: To investigate the expression of proliferating cell nuclear antigen and bcl-2 and to study their relationship with cervical squamocellular carcinoma.

目的： 探讨增殖细胞核抗原和凋亡抑制基因bcl-2产物在宫颈鳞状细胞癌组织中的表达规律以及与宫颈鳞状细胞癌的关系。
