几年前,国际癌症基因组协会(ICGC)在著名的《Nature Communications》杂志,发表了一篇令人瞠目的文章,它为即将到来的癌症基因组学研究时代,奠定了基础。该项目,是由Centro Nacional de Analisis Genómico (CNAG-CRG)和German Cancer Research Center (DKFZ)带领完成的,是一项旨在为体细胞突变检测产生可靠标准的研究,这些体细胞突变是癌症基因组的一个标志。体细胞突变是一个细胞自发获得的遗传改变,可以在细胞分裂和肿瘤生长过程中传递给突变细胞的后代。体细胞突变不同于从父母传递给儿童的种系变异。

1、进入ICGC官网:https://icgc.org/
进入官网之后,往下拉,在左下方,我们就可以看到ICGC的数据类型,比如中国的膀胱癌数据:
2、在网站最上方导航栏进入数据界面:Data Portal
也可以直接点击进入网址:https://dcc.icgc.org/
进入Data Portal之后,我们选择DCC Data Releases进入数据版本
进入数据版本只有,我们可以看到很多数据版本,那么我们选择最新更新的数据
点击current进入数据选择界面
进入到数据界面,点击Projects
然后就到达选择下载界面,在这里我们可以看到也有TCGA、TARGET的数据,如果大家需要分析TCGA或者TARGET的数据库,那么直接进入TCGA和TARGET官网下载和分析就可以了,没有必要在这里选择。生信自学网也有专门的课程讲解TCGA和TARGET数据库挖掘。
3、选择我们感兴趣的研究,比如我们这里选择LIRI-JP
3、选择LIRI-JP进入数据下载页面,我们可以看到LIRI-JP所有的数据,我们可以把所有的这些数据下载下来,下载很简单,直接右键“另存为”
接下来,我们给大家解释一下这些数据:
donor.LIRI-JP.tsv.gz 病人的数据(临床数据)
exp_seq.LIRI-JP.tsv.gz 表达数据(测序数据)
sample.LIRI-JP.tsv.gz 样品信息
simple_somatic_mutation.open.LIRI-JP.tsv.gz 突变数据
specimen.LIRI-JP.tsv.gz 实验处理数据(可以区分正常和癌症)
structural_somatic_mutation.LIRI-JP.tsv.gz 结构变异数据
在这里需要提醒大家的是,ICGC每个项目的数据是不同的,大家需要根据自己研究找到合适的癌症,然后找到所有的这些数据。
当然也可以购买生信自学网给大家准备的《ICGC数据库挖掘视频课程》
