Biomarker Bulletin: April 19, 2011

Biomarker Bulletin is an occasionally recurring update of news focused on biomarkers aggregated at BiomarkerCommons.org. Biomarkers are physical, functional or biochemical indicators of normal physiological or disease processes. The individualization of disease management — personalized medicine — is dependent on developing biomarkers that promote specific clinical domains, including early detection, risk, diagnosis, prognosis and predicted response to therapy.

New Strategic Plan for NIH Obesity Research Seeks to Curb Epidemic

To combat the obesity epidemic, the National Institutes of Health is encouraging diverse scientific investigations through a new Strategic Plan for NIH Obesity Research.

More than one-third of adults in the United States and nearly 17 percent of the nation’s children are now obese, which increases a person’s chance of developing many health problems, including type 2 diabetes, heart disease, high blood pressure, fatty liver disease, and some cancers. Although American obesity rates leveled off in 2007, in 2008, obesity-related medical costs were an estimated $147 billion. Government, nonprofit and community groups, businesses, health care professionals, schools, families, and individuals are taking action to address this public health problem — and research can provide the foundation for these efforts.

Vitamin D Regulates Genes Associated with Susceptibility to Autoimmune Diseases

Vitamin D is, at this point, probably one of the trendiest vitamins around. Everyone suddenly seems to be getting their vitamin D level tested (specifically vitamin D3 or 25(OH)D, also called calcidiol) and, when levels are found to be deficient, taking supplements. In November 2010, the Institute of Medicine tripled its daily recommendations for vitamin D from 200 International Units to 600 [1]. Severe vitamin D deficiency causes rickets, which leads to a softening and weakening of the bones, so milk has been fortified with vitamin D to prevent rickets. Less dramatic vitamin D deficiency has been implicated in ailments ranging from cancer to heart disease to schizophrenia to autoimmune diseases to colds and the flu. But how does vitamin D act in the body — how can it contribute to so many different physiological processes?
