[BioC] How to get gene symbol after deseq?

[Fabrice Tourre]

Dear experts,

After I have run deseq, I got a list of genes. They are something like
as follow.

> resSig[,1]
[1] "ENSMUSG00000022150+ENSMUSG00000079102:009"
[2] "ENSMUSG00000026727:016"
[3] "ENSMUSG00000026727:004"
[4] "ENSMUSG00000022150+ENSMUSG00000079102:015"
[5] "ENSMUSG00000025730:010"
[6] "ENSMUSG00000005836:007"
[7] "ENSMUSG00000073139:001"

How can I get back the gene symbol for each ID?

Thank you very much in advance.
