查询词典 ras

A malignant transformant line 3T3 (T24) was obtained by transfection of mouse fibroblast NIH3T3 cells with pMAMneo-T24-ras plasmid. 3T3 (T24) cells were cultured continuously in the presence of benzamide , an NAD site inhibitor of poly polymerase .

将12位密码子突变的活化ras癌基因全cDNA序列克隆到真核表达载体pSV2neo和pMAMneo上，获得了相应的重组质粒pSV2neo-T24-ras和pMAMneo-T24-ras，将pMAMneo-T24-ras质粒利用基因转移方法导入小鼠成纤维细胞NIH3T3中，活化的ras癌基因可使受体细胞发生恶性转化。

Purpose To detect the DNA lesion in k-ras gene caused by benzidine at the level of nucleic acid.

目的在核酸序列水平定位检测联苯胺对Ivras基因的DNA损伤。

Objectives Chymase, the rate-limiting enzyme of the RAS system, has been considered to be closely associated with the cardiac-vascular disease as well as hypertension, cardiac hypertrophy, congestive heart failure and atherosclerosis, and diabetic complication.

临床研究证实严格控制血糖对2型糖尿病患者可以延缓和减轻并发症的出现和发展，在两个大型实验中得以证实，但是不能彻底阻止其进一步的发展与发生。

First, some researchers still put emphasis on grammatical descriptions of the evidential systems in some highly-inflectional languages. Second, the researches seem to be confined to the lexis and clausal level, and the study of evidentiality at discourse and genre level is much less than enough. In addition, the review of the research on English RAs has shown that few systematic researches on evidentiality in academic discourse have been conducted. Third, there are few researches on what evidentiality can do for language users and especially on the interpersonal functions of evidentiality.

目前的言据性研究主要集中于以下几个方面：1有些研究者仍然把重点放在一些屈折性语言的据素的语法描写上，而这种语法描写只是问题的一个方面，而且对于英语这样非屈折性语言，对据素的语法描写似乎并没有实际意义。2对言据性的研究大多都还停留在词汇和句子层面，在语篇和语类的层面的研究并不充分，尤其对学术语篇中言据性系统性的研究寥寥。3对言据性在语篇中的人际功能的研究很少。

Objective Applying randomized terminal linker-dependent PCR to detect the DNA damage of ras gene induced by dichloroacetic acid.

目的研究二氯乙酸(dichloroacetic acid，DCA)对ras基因的DNA损伤作用，探讨其致癌作用分子机制。

Dichloroacetic acid ; ras gene ; DNA damage ; Randomized terminal linker-dependent PCR

二氯乙酸； ras基因； DNA损伤；依赖随机化末端连接物聚合酶链式反应

Analysis of five other epigenetically repressed genes indicates that Ras directs the silencing of multiple unrelated genes through a largely common pathway.

分析另外5个表观抑制基因显示Ras通过一个主要的共有通路指导多相关基因的沉寂。
