Personal History:

Essential hypertension is a complex, multifactorial disease arising from the interaction of genetics and environmental influences. Although a great deal has been learned, we have yet to elucidate the molecular mechanisms of this disease. Our goal is to determine the molecular pathways involved in the modulation of blood pressure and to develop model systems that facilitate the study of those pathways.

Traditional transgenic model systems of human disease may be compromised by compensatory changes in gene expression that arise during development. Moreover, inappropriate temporal or spatial expression of the gene under investigation is likely to limit the value of the model.

Dr. Jones has extensive experience in the regulation of gene expression and has incorporated this expertise in the design and development of molecular tools that allow us to overcome many of the limitations of traditional transgenic systems. Dr. Jones has developed several model systems for the study of important genes in human hypertension. These systems incorporate single-copy, targeted genomic integration of the gene of interest and allow us to exert spatial and temporal control over its expression.

Dr. Jones also has considerable interest in elaborating the molecular mechanism of blood pressure regulation. He has identified several novel protein interacting partners of the D1 and D3 dopamine receptors—proteins that are known to play significant roles in blood pressure regulation by modulating water and salt homeostasis. The identification of sorting nexin 5 (Snx5) as an Interacting partner of the D1 dopamine receptor, has provided considerable insight into a previously unknown, yet vitally important, mechanism of cellular trafficking of the dopamine receptor in response to an agonist.
