The Program in Physiological Genomics of the Department of Physiology and Pharmacology is focused on understanding the genetic components of pathophysiological conditions of the cardiovascular, renal and autoimmune systems. The most prominent of all complex traits investigated in the Joe laboratory is blood pressure regulation. Rat models serve as valuable alternatives to human studies for the identification and characterization of genetic factors/genes. The main strategy is to identify the disease causative genetic factor/gene based on its location on the rat genome by linkage analysis and substitution mapping and/or gene expression and protein expression profiling using whole genome systems biology approaches. We have identified at least 16 different genomic regions that harbor quantitative trait loci (QTLs) for hypertension in rats and successfully mapped several of these regions to unparalleled resolutions of a few kilobases. Positional cloning projects have progressed to the identification of multiple novel genes as prominent BP QTLs in rats. Methodical mechanistic studies spanning from molecular to whole-organism physiology/pathophysiology are underway to determine the functional significance of the novel BP QTLs identified. Genetic-engineering technologies such as the application of zinc-finger nuclease-based targeted gene disruption for creation of 'knock-out' and 'knock-in' rat models are also strategies integrated into our research for validation of the positionally cloned causal genetic biomarkers of blood pressure regulation. Finally, the translational significance of our work is exemplified by the validation of the positionally cloned rat genes as being associated or linked with human hypertension.
