However, finding a driver gene does not mean that cancer is overcome. Shortly, cancer cells activate another driver gene. It need a deeper mechanistic investigation of the link between protein structure and cancer driver gene. Driver genes have high protein-protein connectivity. Protein map coding ...
图1:乘客突变(passenger mutation)和驱动突变(driver mutation)。肿瘤测序显示,转化细胞的基因结构以大量突变的积累为特征。然而,在这些基因变化中,有一小部分驱动突变具有积极的致癌特性,其余的乘客突变是惰性变化,在肿瘤发生过程中既不被选择也不被对抗。区分驱动突变和客体突变是一项关键的研究目标,因为前者是潜在的治...

目前识别driver mutation 的方法大致可以分为两类:1.基于突变频率 2. 基于功能影响评分 基于突变频率的方法最适合于寻找频繁发生的driver事件,而应用于罕见的driver事件时性能较差。 相比之下,基于功能影响的方法无法找到人们对基因组元素了解不足或注释不明确的驱动因素。

We used a combination of multi-region and single-cell targeted next generation sequencing to assess the diversity of somatic driver gene mutations in IPMNs. The resulting data, combined with evolutionary modeling, whole exome sequencing, and in situ mutation detection, show that the earliest stages...
we integrated SNV and CNV data to obtain a mutation matrix, and calculated the gene mutation score (Eq.2) and the Euclidean distance (Eq.3) between two genes according to the matrix. Next, the mutation effect function between genes was calculated according to Eq.4. In the second step, we...
