To study the role of B vitamins in health and age-related diseases at epidemiological, biochemical and molecular levels.
1. Determine the impact of mandatory food folic acid fortification in the United States.
2. Determine the interrelationships between B vitamin status, methionine intake, genetic polymorphism and plasma homocysteine.
3. Determine the hereditary association of plasma homocysteine and vitamin status.
4. Determine the biochemical, pathological and functional impact of nutritional and genetic disruptions of one-carbon metabolism, in animal models of age-related vascular and neurological dysfunction, with emphasis on the roles of B vitamins, homocysteine and methionine in tissue-specific susceptibility to disease.
5. To develop and validate a method for simultaneous measurement of micronutrients and biomarkers in blood samples.
