How does fish liver gene expression change under confinement stress?
Microarrays track the time course of gilthead sea bream liver transcriptional responses after confinement stress linked to cortisol biology.

How does fish liver gene expression change under confinement stress?
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
What species was studied?
gilthead sea bream ( Sparus aurata ) from parents selected for low- or high-cortisol response also show divergent responses []
What stressor is central?
after handling and exposure to a confinement stressor [,].
What they did
Used microarray profiling of liver after confinement exposure in Sparus aurata, relating responses to stress/cortisol physiology.
What they found
Time-dependent liver stress-response transcripts; connects to known cortisol and GHR stress sensitivity in this aquaculture species.
The limits
What it doesn't show
Does not itself complete a full breeding program for low-stress fish.
