Expression of genes in zebra finches that differ in their response to stress. 


Taking advantage of the fact that we had artificially selected lines of zebra finches for their response to a standardized stressor, we are using microarray techniques to analyse gene expression in these birds. We are in the process of analysing these data at the moment in conjunction with the Liverpool Microarray Facility, and David Clayton’s lab when he was at Illinois. David has now moved to Queen Mary (http://claytonlab.sbcs.qmul.ac.uk). 

Some papers on the finch selected lines are:
