Research Interests

Project I: Cardiovascular Disease, Diet & Oxidative Stress

Diet, oxidative stress and cardiovascular disease: Cardiovascular disease (CVD) is one of the leading causes of death in the United States. Lifestyle changes such as diet and exercise can help protect against CVD. Oxidative stress (increased production of oxygen and nitrogen derived free radicals and a lower antioxidant defense) plays an important role in CVD especially atherosclerosis (blockage of arteries). Our laboratory is interested in studying the interplay between diet, oxidative stress and the risk to atherosclerosis using animal models susceptible to atherosclerosis (Apo E-/- mice, LDLr-/- mice) or mice that over express antioxidant defense enzymes such as catalase transgenic mice or Bob-Cat mice.

Project II – Obesity, Aging & Cardiovascular Disease

Adipose tissue-vascular crosstalk: Obesity is a worldwide public health concern that predisposes individuals to increased risk to cardiovascular disease (CVD) and Type 2 diabetes. West Virginia has the second largest number of people with obesity in the United States. Increase in visceral/abdominal adiposity is a hallmark for obesity. However, increase in ectopic fat (deposition of fat in non-adipose tissue) is correlated with obesity and is also a marker for future cardiovascular events. Aging, an independent risk factor for CVD, results in adipose dysfunction. Studies in our laboratory are investigating the effect of aging and obesity on the distribution and function of epicardial/perivascular fat (the fat that surrounds the heart and the coronaries) in animal models and humans with coronary artery disease. We are interested in studying the role of microRNA and epigenetic pathways in aging related adipose dysfunction.

Project III – Endometriosis, Pain and Oxidative Stress

Oxidative stress, Pain and Endometriosis: Endometriosis is a disease that afflicts women of child-bearing age. The two major clinical characteristics of this disease are infertility and pain. Though several theories have been put forward, the etiology of endometriosis is still unknown. Clinical studies from our laboratory showed the important etiological role for oxidative stress in endometriosis and the ability of antioxidant supplementation to women with endometriosis relieved the symptoms. In collaboration with the Department of Obstetrics and Gynecology, Marshall University Joan C. Edwards School of Medicine, we are continuing to explore the role of microRNA in the etiology of pain associated with endometriosis. We are also investigating the role of novel antioxidants in alleviating endometriosis associated pain. Our goal is to identify potential targets for therapeutics for women with endometriosis.
