To find the significance of oncogenes in the development of prostate cancer.

肿瘤的发生是多步骤的，涉及到多种癌基因和抑癌基因的改变［'］，我们采用免疫组化法对50例前列腺癌组织中bcl－2、P和c－erb－B。

The occurrence and growth of tumor correlate with the activation of oncogene and the mutation and/or absence of anti-oncogene.

肿瘤的发生发展与癌基因的激活和/或抑癌基因的突变、缺失密切相关。

The offsprings were identified by PCR, the perfusion of human blood serum and RT-PCR.

RT-PCR检测转基因的表达情况，发现在转基因小鼠的心脏组织中有CD59基因、MCP基因的表达。

In this research, we employed 260 wheat cultivars selected from the different wheat-growing areas in China to be as materials for identifying vernalization gene loci of Vrn-A1, Vrn-B1, Vrn-D1 and Vrn-B3 by using STS markers and by field growth examination together, in order to make clear the effects of growth habit in wheat on dominant-recessive regarding four vernalization gene locus.

本文选取来自中国各麦区的260份小麦品种，用STS标记对其Vrn-A1、Vrn-B1、Vrn-D1和Vrn-B3四个春化基因位点进行检测，并结合小麦田间生长情况记录，探讨春化基因的4个位点显隐性情况对品种冬春性的影响。

Methods: The genomic DNA were extracted from 40 patients with early-onset Parkinson's disease and 100 normal controls. Seven exons of Parkin gene were amplified, and deletions and point mutations were analyzed by single-strand conformation polymorphism.

以40例早发性帕金森病患者和100例正常人为研究对象，提取基因组DNA，扩增Parkin基因的7对外显子，并用单链构象多态性的方法分析Parkin基因的缺失突变和点突变情况。

Methods Mammalian expression vectors containing human MGMT gene were tranferred into PBMC in vitro via liposome. Realtime PCR and Western blot were used to detect the expression of MGMT at mRNA and protein levels.

利用脂质体法将含入MGMT基因的真核表达载体导入体外培养的外周血单个核细胞，实时PCR及Western blot检测目的基因mRNA及蛋白水平的表达。

Apparently, a mutation in this gene—or, more probably, in the control system that activates it—gave rise to Volvox.

显然这种基因的突变——或者可能是激活基因的调节系统的突变——出现在了团藻中。

Apparently, a mutation in this gene—or, more probably, in the control system that activates it—gave rise to Volvox.

显然这个基因的突变，或更可能是激活这个基因的控制机制的突变产生了团藻。

Depending on how it is counted, the DNA of chimpanzees is 95 percent to 98.7 percent the same as that of humans.

依据这样的数据，chimpanzees的基因和人类基因的相似度达到了95％到98.7%。

The identification of thrombopoietin, and the demonstration that administration to normal experimental animals and pre-and post-chemotherapy patients with advanced cancer with recombinant TPO results in a several-fold increases in platelet count, has opened the possibility of using TPO to rescue patients from lifethreatening thrombocytopenia with above mentioned situations, while the cloning of TPO cDNA also has made it possible to treat thrombocytopenia using TPO gene.

各种原因所致的血小板减少症，常因血小板严重减低而出现致命性出血合并症。而目前唯一有效的治疗措施是输注血小板。但由于目前血小板输注这一治疗手段尚存在许多弊端，人们迫切需要早日解决这一难题。血小板生成素(thrombopoietin， TPO)基因的克隆为采用基因治疗手段治疗血小板减少症带来了希望。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
