Hello,

I would like to ask if you know any R package which will help me in doing a mass search for genes relations and which pathways are they corresponding to?
E.g I had about 34 thousand genes (i.e  ENSG00000146648 - coded in ensembl DB) derived from GBM cancer patients. I want to list their functions and check in which pathways each of them is involved. Do you have any ideas? 

I was looking for a similar question, but I could not find one (expect biopython, which I am not using - unless I will be forced to. ;))
You can get GO annotations for genes in Ensembl. Use either the [Ensembl perl API][1] or the Bioconductor [biomaRt R package][2].
