Research Interests

Research projects in Dr. Abraham’s laboratory funded by NIH, focus on vascular dysfunction which is a prelude to obesity and cardiovascular disease including hypertension, stroke, and diabetes. Heme oxygenase (HO)-1 is the enzyme in humans that degrades heme in the spleen to generate iron (iron utilization), carAbraham_Inflammation_fig1bon monoxide (CO) and bilirubin (antioxidant). The research focuses on how the HO-1 (the most potent anti-oxidant gene in the human body)-adiponectin-EET module play an essential role in vascular function. We believe that HO-1 acts as a molecular “switch” to genetically reprogram stem cells and, subsequently, vascular endothelium through activation of a unique signaling cascade that results in the amplification of protective circuits that provide resistance to vascular dysfunction. Increased HO-1 expression provides protection for stem cell function and bone formation and, also, decreases adiposity. HO-1 also serves as the mediator of cross-talk between adipose tissue and the vasculature. Abraham_Mesenchymal_fig2Our studies focus on the impact of adipocyte stem cell dysfunction on vascular endothelial integrity through the role of HO-1. HO-1 expression in epicardial tissue provides protection to heart function and attenuates myocardial infarction (MI) and heart failure. Both human and animal models of diabetes and obesity are utilized to examine the use of stem cell intervention and gene therapy to amplify HO-1 levels. Additionally, our research approach is a powerful tool in the identification of therapeutic strategies and novel biomarkers for cardiovascular and metabolic disease (e.g. circulating endothelial cells and prAbraham_Biomarkers_fig3ogenitor stem cells [EPCs] for better prognosis). We believe that the effect of anti-diabetic drugs alone, or in combination with antioxidant genes, has a differential impact on stem cell function and vascular disease as well as on stem cell differentiation into adipocytes and osteoblasts. The genomic approach and gene array analysis described in various publications from our laboratory represents a powerful tool to systematically investigate therapeutic approaches and, thus facilitate translational research in hypertension, Abraham_Endothelial_fig4diabetes and the metabolic syndrome using stem cells and / or gene therapy. Additionally, our laboratory is focusing on the identification of biomarkers as diagnostic tools for monitoring the progression of several genetic diseases in order to predict future pathophysiological conditions and the potential use of cell therapy for disease prevention. Dr. Abraham’s group is collaborating with Dr. Kathleen O’Hanlon (Family Medicine), Drs. Ellen Thompson and Robert Touchon (Cardiology) and Ryan Stone (OB/GYN) and Dr. Zeid Khitan (Chief, Nephrology) and Dr. Yoram Elitsur (Pediatrics) to identify blood biomarkers for disease progression.
