[BioC] (no subject)

[McGee, Monnie]

Dear Anupam,

I am responding to you message about finding signaling pathways to which a list of over/under expressed genes belong.

There are several tools for this: Reactome, OntoExpress, PathExpress, CLASSIFI (requires clustering of the genes using some type of clustering tool before use).  
Most of these are available online, and some are actually websites to which you submit your list and then wait for a response.  You can find any of these by searching for them using any Internet search engine.

Bioconductor has a several packages that contain functions to do find pathway membership.  GOstats and goTools come to mind immediately.   There are probably others.

I hope that gets your started.  

Best Regards,
Monnie McGee
