(Santa Barbara, Calif.) While legions of medical researchers have been looking to understand the genetic basis of disease and how mutations may affect human health, a group of biomedical researchers at UC Santa Barbara is studying the metabolism of cells and their surrounding tissue, to ferret out ways in which certain diseases begin. This approach, which includes computer modeling, can be applied to Type 2 diabetes, autoimmune diseases, and neurodegenerative diseases, among others.
Scientists at UCSB have published groundbreaking results of a study of Type 2 diabetes that point to changes in cellular metabolism as the triggering factor for the disease, rather than genetic predisposition. Type 2 diabetes is a chronic condition in which blood sugar or glucose levels are high. It affects a large and growing segment of the human population, especially among the obese. The team of scientists expects the discovery to become a basis for efforts to prevent and cure this disease.
The current work is based on a previous major finding by UCSB's Jamey Marth, who determined the identity of the molecular building blocks needed in constructing the four types of macromolecules of all cells when he was based at the Howard Hughes Medical Institute in La Jolla in 2008. These include the innate, genetic macromolecules, such as nucleic acids (DNA and RNA) and their encoded proteins, and the acquired metabolic macromolecules known as glycans and lipids. Marth is a professor in the Department of Molecular, Cellular, and Developmental Biology and the Biomolecular Science and Engineering Program; and holds the John Carbon Chair in Biochemistry and Molecular Biology and the Duncan and Suzanne Mellichamp Chair in Systems Biology. He is also a professor with the Sanford-Burnham Medical Research Institute in La Jolla.
