Research Interests

Research in the Stevens laboratory is aimed at determining the role and function of vitamins and dietary phytochemicals in human health and disease. Mass spectrometry-based metabolomics is a new direction in the laboratory for discovery of biological effects and mechanisms of actions.

Project 1: Xanthohumol and metabolic syndrome

Dr. Stevens and his associates have discovered that the hop natural product, xanthohumol, exerts anti-obesity and anti-hyperglycemic effects in animal models of metabolic syndrome. Current research on xanthohumol, now marketed as a dietary supplement and food additive, is focused on its fate in the human body and its effects on gene regulation relevant to lipid and glucose metabolism. Xanthohumol could earn a place in the early treatment of metabolic syndrome to prevent or retard the development of atherosclerosis and diabetes (Funding: NIH/NCCIH and Hopsteiner, Inc.).

Project 2: Vitamin C mitigates cardiovascular disease

Cardiovascular disease finds its origin in a chronic inflammatory state of the vasculature. Dr. Stevens and other investigators of the Linus Pauling Institute have shown that vitamin C supplementation reduces the formation of pro-inflammatory lipid peroxidation products in humans, which is significant because many large clinical trials have not been able to establish any effect of vitamin C on biomarkers of oxidative stress. The Stevens lab is also investigating the beneficial effects of vitamin C in the prevention of tolerance against nitrate therapy.

Other projects:

3) Brain stimulants from the medicinal herb, Centella asiatica, in the fight against Alzheimer’s disease (Funding: NIH/NCCIH).

4) Bioactives from the oilseed crop, meadowfoam (Limnanthes alba) (Funding: Natural Plant Products, Inc.).
