The Division of Molecular Diabetes Research, directed by Rama Natarajan, Ph.D., is at the forefront of research on the complications of diabetes and was the first to study epigenetic changes in diabetic complications.
Rama Natarajan, Ph.D., directs the Division
of Molecular Diabetes Research.
Basic science research in molecular biology, biochemistry and immunology provides the foundation that drives the development of new therapies for diabetes and related complications. City of Hope scientists in this division are performing cutting-edge research in these areas.
Diabetes is the leading cause of kidney failure and a significant risk factor for the development of vascular complications like atherosclerosis. Our researchers are working to determine molecular mechanisms and factors mediating these complications and to develop strategies to prevent and reverse these complications. The researchers' study of atherosclerosis and kidney disease includes both diabetic animal models and humans.
Scientists in this division are examining the molecular links between diabetes, obesity, metabolism, cancer and aging, including the role of various nuclear receptors.
Translational approaches using small molecules are also being investigated. Researchers are using potential gene therapy and RNA interference translational approaches to inhibit key genes associated with diabetic complications. They are also developing synthetic small molecules to target genes that promote obesity and related metabolic changes.
Our researchers have identified a molecular link between physical activity and insulin sensitivity. They are using animal models to characterize key mechanisms in exercise's effects on skeletal muscle's energy metabolism and growth.
In addition, our researchers are performing important studies to develop novel methods to induce immune tolerance for the treatment of type 1 diabetes and also identify new cellular targets that can lead to cell-based therapies for diabetes. The results of these studies with immune cells can lead to more effective approaches in the treatment diabetes and to improved success of islet-cell transplantation.
Overall, this division within the Department of Diabetes and Metabolic Research uses several state-of-the-art computational and systems biology data-analysis methods; genomic and epigenomic profiling approaches; novel transgenic mouse models; and translational approaches with small molecules, antibody and cell-based therapies in animal models and humans in its quest to advance the field of diabetes research.
