About
There is tremendous interest in finding interactions between biological factors and stress in the development of depression. Progress has been limited however, because it is difficult to predict the onset of stress beforehand and because the type of stress encountered varies widely between individuals. In our primary study, we seek to overcome these barriers by utilizing medical internship as a model of stress. Medical internship, the first year of professional physician training, presents a unique situation where the onset of a uniform, substantial stressor can be prospectively predicted. To identify genes involved in depression, we are performing genome-wide association and coding exome studies on a sample of over 10,000 interns. Beyond genes, we are utilizing the internship model to identify, psychological factors, epigenetic patterns and serum protein levels that moderate the relationship between stress and depression.
