msigdf + clusterProfiler全方位支持MSigDb

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

## 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:

enricher 做超几何分布检验:

de <- names(geneList)[1:100]
x <- enricher(de, TERM2GENE = c2)

head 瞄一眼结果:

> head(x, 3)

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:

> head(y, 3)

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)

msigdf + clusterProfiler全方位支持MSigDb

> gseaplot2(y, 1)

msigdf + clusterProfiler全方位支持MSigDb
