    We investigate the mechanisms by which nuclear receptors (such as PPARs) and coactivator proteins control programs of metabolism and inflammation in tissues. Our work is highly pertinent to various disease states, such as type 2 diabetes mellitus, coronary artery disease, autoimmunity and aging.

    Our lab is interested in understanding molecular processes that underlie aging and age-associated pathologies in mammals. We focus on a family of genes, the SIRTs, which regulate stress resistance and lifespan in lower organisms such as yeast, worms, and flies. In mammals, we recently uncovered a number of ways in which SIRT factors may contribute to cellular and organismal aging by regulating resistance to various forms of stress. We have now begun to characterize the molecular mechanisms b..

    Investigation of the epidemiology of diabetic ketoacidosis (DKA) at a public hospital. All cases of DKA at SCVMC occurring over the past 5 years have been identified. Of the 480 cases of DKA, about 1/3 are in Type II diabetics, and 2/3 in Type I diabetics. We are exploring the causes of DKA in the two groups.

    Our medical education research group is developing and validating the best educational practices to train competent, compassionate, and ethical physicians and physician-scientists. We are studying the use of standardized patients and other modalities to improve clinical skill training and reasoning. We are interested in applying the rigor of clinical investigation to education research. My areas of clinical interest in endocrinology include disorders of the pituitary, thyroid, and gonad.

    We are interested in studying the pathophysiological processes that contribute to glucose intolerance and type 2 diabetes mellitus. My current research focuses on characterizing pancreatic beta-cell function in populations with significant insulin resistance and vulnerability to developing diabetes: individuals with schizophrenia, morbid obesity, and history of gestational diabetes.

    Our research interests are in the general area of cellular lipid and lipoprotein metabolism. The work is aimed primarily at understanding the mechanisms regulating cholesterol and triglyceride accumulation in cells. We utilize a variety of techniques from cell biology, biochemistry, and molecular biology.

    Dr. McLaughlin conducts a number of clinical research studies related to obesity, insulin resistance, diabetes, and cardiovascular disease. Current studies include: 1) the impact of macronutrient composition on weight loss and cardiocascular risk (diabetic and nondiabetic patients); 2) comparison of weight loss and cardiovascular risk reduction in diabetic patients treated with different classes of antihyperglycemic drugs; 3) the role of the adipocyte in modulating insulin resistance
