Gary Patti, the Michael and Tana Powell Associate Professor of Chemistry in Arts & Sciences at Washington University in St. Louis, has been awarded $4.8 million in two separate National Institutes of Health (NIH) grants focused on improving the accessibility of metabolomics — the study of the biochemical reactions that underlie metabolism.
A simple experiment, originally undertaken to test a new methodology, unexpectedly disproved the prevailing notion of cancer metabolism.
For more than 80 years, scientists have thought that cancer cells fuel their explosive growth by soaking up glucose from the blood, using its energy and atoms to crank out duplicate sets of cellular components. But is this really true? Work in a metabolomics laboratory at Washington University in St. Louis suggests not.
An enzyme secreted by the body’s fat tissue controls energy levels in the brain, according to new research led by Shin-ichiro Imai, MD, PhD, of the School of Medicine. The findings, in mice, underscore a role for the body’s fat tissue in controlling the brain’s response to food scarcity, and suggest there is an optimal amount of body fat for maximizing health and longevity.
Enzymes linked to diabetes and obesity appear to play key roles in arthritis and leukemia, potentially opening up new avenues for treating these diverse diseases, according to researchers Clay Semenkovich, MD, (left) and Irfan Lodhi, PhD, at the School of Medicine.
New research demonstrates that obesity does not always go hand in hand with metabolic changes in the body that can lead to diabetes, heart disease and stroke. Washington University School of Medicine researchers found that a subset of obese people do not have common metabolic abnormalities associated with obesity, and they don’t develop them when they gain more weight.
William H. Daughaday, MD, a leading diabetes researcher, world authority on growth hormone, and the former director of the metabolism division at Washington University School of Medicine in St. Louis, died after a long illness Friday, May 3, 2013, in Milwaukee. He was 95.
Resveratrol, an ingredient in red wine thought to improve insulin sensitivity, reduce risk of heart disease and increase longevity, does not appear to have those benefits in healthy women, according to new research from Washington University School of Medicine in St. Louis.
Researchers at Washington University School of Medicine in St. Louis, led by Philip Stahl, PhD, professor of cell biology and physiology have identified a potent regulator of sensitivity to insulin, the hormone that controls blood sugar levels. The new findings may help scientists find better treatments for type 2 diabetes, obesity and other health problems caused by the body’s inability to properly regulate blood sugar.
Nutrition and longevity researchers, including Luigi Fontana, MD, PhD, have found more evidence that eating less may help people live longer. They report that individuals who significantly reduce their calorie intake have lower core body temperatures. Mice and rats consuming fewer calories also have lower core body temperatures, and they live significantly longer than littermates eating a standard diet.
