中心体

These data suggested that the centrin isoforms played different roles in different stages of spermatogenesis. The centrin-1 gene was revealed to be relevant to the centriolar translocation to the posterior pole of cell and the elaboration of flagellum during spermiogenesis, while the centrin-2 and centrin-3 might play roles in spermatogonial mitosis but were not involved in the spermatid differentiation process.

这些结果提示，Centrin同源基因在精子发生的不同阶段发挥不同功能，其中Centrin-1与精子细胞分化期的中心体后移、鞭毛的生成及精子中轴形成可能密切相关，Centrin-2和-3则可能在精原细胞有丝分裂中起作用，而与精子细胞变态分化无关。

We think that centrin play an important role in meiosis during Urechis unicinctus sperm metamorphosis difference and we also think that centrin may be related to trochophore cilia and sperm tail formation,and reconstraction of centrosome after fertilization.

我们推测Centrin在单环刺螠精子发生过程中减数分裂或精子细胞变态分化过程中发挥作用；在单环刺螠早期胚胎发育中，Centrin可能与受精后中心体的重建及担轮幼虫的纤毛形成有关。

The ring has a central annular body portion (21) with a raised bearing surface (22) thereon adapted to contact the inner surface of said calandria tube and prevent contact between said outer surface and said inner surface.

该环件具有一环形的中心体部分（21），该部分具有一适于和所述排管容器管的内表面接触的凸起的环形支承面（22），并且可以防止所述外表面与所述内表面接触。

Of or relating to a centrosome.

属于或与细胞的中心体有关。

Therefore, abnormal centrosome is common in tumor cells, and centrosome amplification is probably an early event in the origination and development of cancer.

因此，中心体异常也是肿瘤细胞的普遍特征，并且可能出现在肿瘤发生的早期阶段。

Among all the factors leading to genetic instability,centrosome and telomer...

在众多可能引起基因组不稳定的相关因素中，中心体和端粒酶所起的作用较为重要，且已引起越来越广泛的关注。

Usually, abnormal centrosome is found in early stage of tumorigenesis and play an important role in initiation, progression and evolution of cancer.

中心体异常在肿瘤的发生发展演化过程中可能具有重要作用。

Centrosome is the major microtubule-organizing center in animal cells.

在动物细胞中中心体是微管组织的主要细胞器。

Thus, centrosome abnormalities can lead to chromosome instability and cancer.

当中心体功能出现障碍时，往往伴随染色体分离异常，从而导致癌症的发生。

A large amount of evidence has implicated BRCA1 in multiple cellular functions including DNA damage response, transcriptional regulation, and control of centrosome duplication.

有大量的证据表明BRCA1具有有很多功能，包括DNA损伤反应，转录调控和控制中心体的复制。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
