Transcription profiling of brain tissue from trout with different dominace status

ABSTRACT: Dominance hierarchies of rainbow trout Trout form linear dominance hierarchies where there is a dominant, subdominant and subordinate. The dominant is the most aggressive, followed by the subdominant and the subordinate is the least dominant. Fish were scored on their aggressive performance to calculate position within the hierarchy, and once formed the hierarchies are very stable. Hypothesis: Gene expression is different in the brains of individuals with different dominance status. Six hierarchies containing a dominant, subdominant and subordinate were assessed behaviourally then killed and the brain removed. These were run in a reference based design. Hypothesis: On removal of the dominant the subdominant fish will become dominant and its transcript profile will become similar to the established dominant. The second experiment involved removing the dominant from an established hierarchy and then examining gene expression at 2hr, 48hr and 1 week in the new dominant.
