2019-06-21  本文已影响58人  郑宝童

Identification of cancer dysfunctional subpathway by integrating DNA-methylation, copy number variation, and gene-expression data
文章主要内容:通过整合DNA甲基化、拷贝数变异和基因表达数据识别癌症功能失调子路径
要点:

背景意义部分咱就先略过:你可以上网下载文章自行查看
我就直接上流程图将文章方法部分:

ICDS

关键信息:Usually, the statistic S followed a χ2 distribution with 2k degrees of freedom, and we then calculated the null hypothesis p-value of the statistic S. Finally, we converted the p-value to a z-score according to the inverse-normal cumulativedistribution function (CDF), and the z-score was taken as the RS of each gene in cancer


文章将ICDS找到的显著子通路与gsea、spia、SubpathwayMiner方法找的通路做对比。论证出文章方法的可靠性。
