肌动蛋白

Actin has been identified in nuclear skeleton, nucleolar matrix and chromosome scaffold of these plants.

结果显示，三种植物细胞核骨架、核仁骨架和染色体骨架上存在肌动蛋白。

The immunocytochemistry was used to identify the RASMC.RESULTS: The RASMC were successfully cultured by the adherent method of tissue explants and grown in the "peak- valley" mode. The cultured RASMC were fusiform shape with a big oviform or round nuclei rich in cytoplasm. Immunohistochemical method ( S-P method) showed strong expression of a- smooth muscle actin.

结果：组织块贴壁法成功培养出SD大鼠胸主动脉平滑肌细胞，培养的细胞呈典型&峰-谷&样生长，HE染色细胞呈梭形，胞浆丰富，核大而圆或椭圆，免疫组化S-P法检测a-平滑肌肌动蛋白单克隆抗体呈强阳性表达。

The binding between TACO and cell membrane is non-actin related. The result can provide evidence for exploring the function of TACO at the early stage of cell phagocytose.

TACO与细胞膜具有非依赖肌动蛋白方式的结合，这一结果为阐释TACO在细胞吞噬初始阶段的功能提供了有力的实验依据。

Examination the cell shape and pseudopodia with confocal laser scanning microscopy, scanning electron microscopy, and atomic force microscopy, we found that cell spreading well on nanogrooved substrates and their body was more flat and slim; meanwhile, on plain substrates, cells were mostly round.

纳米沟槽能很好地促进细胞贴壁黏附、铺展、生长和增殖，并影响细胞的周期；纳米沟槽诱导细胞骨架发生重组，肌动蛋白骨架沿着纳米沟槽的方向取向排列；纳米沟槽影响细胞伪足形成的方式和形成与细胞中的位置。

Signalling through CXCR4 mediates actin polymerization and pseudopodia formation in cells, and induces chemotactic and migration to target organs. In addition, CXCR4-SDF-1 axis can promote tumor angiogenesis and growth.

CXCR4在肿瘤组织中的表达明显高于正常组织，而肿瘤常见转移部位均为CXCR4的配体基质细胞衍生因子-1(stromal cell derived factor-1，SDF-1)表达丰富的器官，SDF-1与CXCR4结合后可使细胞肌动蛋白丝聚合，形成伪足，从而定向诱导肿瘤细胞迁移到特定的靶器官；此外，CXCR4与其配体SDF-1相互作用可以促进局部新生血管作用，利于肿瘤生长。

A reduction in actin expression was observed by immunoblotting in both nucleus pulpous and anulus fibrous cells, especially in nucleus pulpous cells.

Western免疫印迹结果显示，肌动蛋白在纤维环细胞和髓核细胞中的表达均明显减少，以髓核细胞为著。

In our laboratory a chemically regulatable male sterile expression system had been constructed based on the antisense actin strategy and putatively transgenic tobacco plants with Kan-resistance had been obtained.

本实验室在自行研究成功的反义肌动蛋白雄性不育策略的基础上，构建成由铜调控的在绒毡层细胞特异表达anti-actin基因的植物表达系统，转化烟草获得由kan抗性筛选的烟草植株。

Through analyzing the consecutive deconvolved 3-D images of secretory vesicles, we calculated the 3-D diffusion coefficients of vesicles in both resting and stimulated cells, further obtained the relative numbers of released vesicles in readily releasable pool and the rate of recruitment for this pool during certain period after stimulation applied,and analyzed the process of that the filamentous actin regulated the mobility of secretory vesicles.

我们通过对反卷积处理后分泌囊泡的三维动态图像的分析，计算出囊泡在细胞静息和被刺激状态下的三维扩散系数，得到刺激后立即释放库囊泡释放的相对数量和该库的补充速率，并分析了纤维状肌动蛋白对囊泡运动的调控过程。

Immunohistolochemical stain by monoclonal antibodies for growth factors and actin was used to detect whether there are abnormal expressions in saccular aneurysms.

利用血小板源性生长因子、转化生长因子（TGF-β1）、血管内皮细胞生长因子和肌动蛋白的单克隆抗体进行免疫组织化学染色。

SP-R mRNA in nasal mucosa, obtained from two groups, were used to do reverse transcriptive polymerase chain reaction and Southern blot.

以β-肌动蛋白作内标准，利用逆转录-多聚酶链反应(reverse transcriptive polymerase chain reaction， RT-PCR)，对变应性鼻炎模型组和对照组大鼠鼻粘膜SP-R mRNA进行了定量研究。

And if officials on the take are not parroting the opinions of these companies, what can we suppose the money they receive is for?

如果受贿的官员不鹦鹉学舌般地复述这些公司的看法，那他们所接受的钱又能用于什么目的呢？

Love them, and love you too, Pitcher.

爱他们，也爱你，投手。
