Cover: Overview of physiological genomics in the rat and the various translational technologies available to relate rat research to human systems. Left: the traditional positional cloning process wherein 2 rats, 1 possessing the phenotype of interest and the other an unaffected control strain, are crossed. The progeny are genotyped and phenotyped, leading to the definition of quantitative trait loci linking the phenotype to specific regions of the genome. The regions are then examined for potential candidate genes, and comparative genomics is used to integrate evidence from other organisms or to translate results to the human genome. Translation of information to the human system is also becoming possible using informatic tools such as ontologies. Various ontologies are shown connecting elements of the experimental paradigm to related human data.
