查询词典 mutant

In this study we build a Mycobacterium marinum random mutant libratory with MycoMarT7 transposon phage, found two cell wall virulence genes with colony morphology and cording structure strategy and build up virulence detection system in cell and animal model. We concluded that PDIM is critical for the virulence of Mycobacterium marinum.

此目前研究利用一新的人中脑的细胞株MESC2.10来研究a-synuclein53T突变物对多巴胺内环境平衡的影响。

Fibroblast growth factor signaling guides mesodermal cell migration; however, we found some directed dorsal migration in an FGF receptor mutant, which suggests that additional signals are involved.

显微元细胞增长因子信号知道着中胚层的细胞迁移；但是，研究人员发现在突变FGF受体中存在着定向的背离迁移作用，这说明有更多的信号参与到了细胞的运动当中。

Objective To explore the effect of the mutant and expression level of N-ras on chronic myelogenous leukemia.

目的 探讨N-ras基因突变及表达水平与慢性粒细胞白血病发病的关系。

Our study not only proved that calcineurin is the target of nephrotoxic effects of CsA, but also proved that mutant calcineurin is resistant to CsA.
