生信界的网红Stephen Turner在github上有个 msigdf
的包,我在他写这个包的时候,就写了个 gist
,连接 clusterProfiler
,我写 gist
的时候是2016年的8月,很高兴网红还惦记着我的 gist
。
msigdf
这个包把著名的Broad Institute著名的Molecular Signatures Database (MSigDB)数据以data frame的形式打包成 R
包,这样子非常方便使用,当然他后来没有更新,而一个fork的版本, ToledoEM/msigdf
把数据更新为最新版本v6.2,发布于2018年7月。
这个包,天生就方便我们 clusterProfiler
用户,我在《+ Comparison of clusterProfiler and GSEA-P 》一文中,为了比较 clusterProfiler
和Broad Institute出品的GSEA-P软件,特意打包了一个gmt文件,这样方便在注释一样的情况下比较,有了这个示例,其实大家就应该知道,下载gmt文件,然后就可以用 clusterProfiler
分析了,也就是说 clusterProfiler
是支持MSigDb的,再一次敲重点,不要再以为 clusterProfiler
只做 GO 和KEGG了, clusterProfiler
啥都能干。
好了,那么有这个包之后,我们连下载gmt文件都省了,直接载入这个包的数据,然后就可以无缝衔接 clusterProfiler
进行分析,还是原来的配方,还是熟悉的味道,你拥有了《 enrichplot: 让你们对clusterProfiler系列包无法自拔 》的各种可视化功能。
msigdf
包
## devtools::install_github("ToledoEM/msigdf") library(msigdf)
msigdf
包含了人和鼠的数据,总共有以下8个类别:
category | description |
---|---|
H | hallmark gene sets |
C1 | positional gene sets |
C2 | curated gene sets |
C3 | motif gene sets |
C4 | computational gene sets |
C5 | GO gene sets |
C6 | oncogenic signatures |
C7 | immunologic signatures |
在这里我将过滤出 C2
拿来做分析:
library(dplyr) c2 <- msigdf.human %>% filter(category_code == "c2") %>% select(geneset, symbol) %>% as.data.frame
下面这就是我们拿到的 C2
的注释,一个 data.frame
:
> head(c2, 3) geneset symbol 1 NAKAMURA_CANCER_MICROENVIRONMENT_UP COL1A2 2 NAKAMURA_CANCER_MICROENVIRONMENT_UP GPIHBP1 3 NAKAMURA_CANCER_MICROENVIRONMENT_UP RET
接下来是 clusterProfiler
的表演时间,我们还是使用 DOSE
包里的 geneList
数据来做演示,如果不知道怎么搞自己的 geneList
,请移步《 听说你有RNAseq数据却不知道怎么跑GSEA 》。
library(clusterProfiler) data(geneList, package="DOSE")
这里涉及到一个问题, geneList
里的基因是 ENTREZID
,而这里 msigdf
包里是 SYMBOL
,这个简单,无非是个基因ID转换的过程而已,一般而言,对于你自己的注释数据,你不应当有这个问题;假如有,也是一个转换步骤而已,这里做为演示,我把 geneList
的ID给转了,你当然也可以转注释 c2
里的ID。
> id = bitr(names(geneList), "ENTREZID", "SYMBOL", "org.Hs.eg.db") 'select()' returned 1:1 mapping between keys and columns Warning message: In bitr(names(geneList), "ENTREZID", "SYMBOL", "org.Hs.eg.db") : 0.41% of input gene IDs are fail to map... > head(id, 3) ENTREZID SYMBOL 1 4312 MMP1 2 8318 CDC45 3 10874 NMU
我们看到 bitr
的输出,有部分ID是没法转的,这些应该过滤掉,然后用新的ID去给 geneList
重命名即可,要注意ID要一一对应,不能搞错,我这里用了 match
,确保操作没问题:
> geneList = geneList[names(geneList) %in% id[,1]] > names(geneList) = id[match(names(geneList), id[,1]), 2]
好了,现在轮到熟悉的 clusterProfiler
分析了,大家应该都不陌生,在下面的文章中都有介绍过:
用 enricher
做超几何分布检验:
de <- names(geneList)[1:100] x <- enricher(de, TERM2GENE = c2)
用 head
瞄一眼结果:

然后 GSEA
分析用 GSEA
函数:
y <- GSEA(geneList, TERM2GENE = c2)
同样我们也用 head
瞄一眼结果:

用 clusterProfiler
分析有多种好处,一个是你可以用 compareCluster
比较不同的条件,还有就是有非常好的可视化函数,《 enrichplot: 让你们对clusterProfiler系列包无法自拔 》这篇文章你不容错过。
比如:
> cnetplot(x, foldChange=geneList)
> gseaplot2(y, 1)
