Research Summary
Dr. Raben is interested in the chemistry and biochemistry of lipids and lipid enzymes involved in signaling cascades. His laboratory’s major effort is studying the molecular aspects involved in regulating lipid metabolizing signaling enzymes and the physiological roles of this regulation. The control of these enzymes involves the modulation of two key parameters, their sub-cellular distribution and intrinsic enzymatic activity. The importance of this work is underscored by the fact that defects in lipid cascades often contribute to conditions such as diabetes, cardiovascular disease, neurological disorders, immune dysfunctions, and cancer.
