查询词典 mutations

The test reveals mutations in the KRAS oncogene and is carried out on samples of primary tumor removed during surgery, so it can be done before drug treatment is initiated.

该检验可以显示KRAS致癌基因的突变，且这项检验是以手术时取出的原发性肿瘤进行检验，因此这可以在治疗开始前进行。

Objective: To explore the relationship between various mitochondrial DNA tRNA Leu gene/ND-1 gene mutations and type 2 diabetes. Methods: Case-control study was designed.

In contrast to FLT3/ITD mutation, point mutations were not associated with leukocytosis or low complete remission rate.

FLT3/ITD有独特的临床特征：在M3、M5亚型中比例较高；多出现于染色体核型正常和t（15；17）的AML患者；外周血白细胞高；化疗完全缓解率低。

These mutations greatly changed the level of protein synthesis, lipogenesis and JAK2 phosphorylation stimulated by GH, although they did not affect the expression of the GHR and ligand binding.

研究结果表明豚鼠GHR中的一些氨基酸残基的取代并不影响生长激素通过它而诱导的细胞事件，而另外一些氨基酸残基的取代，例如168位的酪氨酸和332位的丝氨酸分别用在其它种属GHR中高度保守的精氨酸和酪氨酸的取代后，则明显地影响着豚鼠GHR介导的GH诱导的生理效应。
