Areas of Research & Specialization
My research interests revolve around minimizing toxicity and/or drug interactions of xenobiotics through better understanding of their effect on drug metabolizing enzymes (DME), especially Cytochrome P450 (CYP) enzymes. Although CYP enzymes normally generate metabolites with diminished biological activity, there are numerous examples where these enzymes mediate the formation of reactive intermediates from chemically inert agents. These reactive metabolites play a key step in initiating cellular damage and cancers. Modification of the activity or expression level of CYP enzymes through exposure to environmental toxins, drugs, or even herbal remedies could potentially affect the clinical outcome of concomitantly-administered drugs. My research interest focuses on identifying the role of CYP enzymes in toxicity induced by drugs, herbal remedies and environmental toxins. Along with the mission of Pacific University and the School of Pharmacy, the outcome of this research will be utilized to advance the level of pharmaceutical care within the community and improve health care literacy among patients. The following projects are being conducted in our research facility in HPC2 and/or in collaboration with scientists from Oregon Health and Science University and University of Saskatchewan (Canada).
Project 1: Studying the Effect of Herbal Remedies on Drug Metabolizing Enzymes
Several animal studies (e.g. those of my postdoctoral research) and human clinical trials have demonstrated that consumption of some natural products decreases morbidity associated with chronic disease. Therefore, public consumption of these products is expected to increase. As a pharmacist, I find the increased use of natural products and nutraceuticals without consultation from the physician or pharmacist is concerning. Therefore in order to provide evidence-based consultation, more understanding of how these products (and their metabolites) affect the activity of drug metabolizing enzymes (DME) is needed. This research focuses on filling this need by studying the bidirectional relationship between natural products and physiological systems. Induction or inhibition of DME by natural products can potentially affect bioavailability, and consequently, toxic effect of concomitantly administered medications.
Project 2: Studying the Effect of Herbal Remedies on Arachidonic Acid Metabolism as a Target for Hypertension Treatment
Substantial evidences indicate that metabolites of Arachidonic acid (AA) via kidney Cytochrome P450 (CYP) enzymes play a critical role in regulation of renal vascular tone, sodium transport, and may participate in the pathogenesis of hypertension. 20-hydroxyeicosatetraenoic acid (20-HETE) is one of the major AA products of CYP metabolism in the kidney. In the renal and peripheral vasculature, 20-HETE is a potent vasoconstrictor that acts by depolarizing the vascular smooth muscles (VSM) cells. Several studies have shown that the vasoconstriction response to vasoconstrictor agonists such as angiotensin II and norepinephrin is secondary to stimulating the endogenous production of 20-HETE in renal VSM cells. In the rat; CYP4A1, CYP4A2 and CYP4A3 were found to exhibit the highest catalytic activity for the formation of 20-HETE. Therefore, specific inhibition of these CYP enzymes could be a potential target for prevention and/or treatment of hypertension mediated by elevation of 20-HETE formation. Our lab is currently investigating the antihypertensive potential of Sulforaphane, the main active ingredient of broccoli sprouts and cruciferous vegetables. We will investigate the potential inhibitory effect of Sulforaphane (SF) on the activity and expression of CYP enzymes involved in 20-HETE formation.
