Department of Physiology and Pharmacology

Program in Physiological Genomics

Physiological genomics laboratory (pgl)

PGL is part of the Department of Physiology and Pharmacology at the UT College of Medicine. It is also part of the Center for Hypertension and Personalized MedicinePGL utilizes an integrated approach of Genetics, Epigenetics, Genomics, Physiology of Model organisms and Bioinformatics to delineate the Genetic elements controlling blood pressure, dysfunctional actions of which may lead to the development of elevated blood pressure or hypertension.

Bina Joe, PhD

Research Interest:

The Physiological Genomics Laboratory (Joe Lab) 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 Crispr/Cas9 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.  The lab has also started focusing on the gut microbiome/microbiota and its link to salt-sensitive hypertension.
