        Academic Background

        David A. Guertin received his B.S. in Biology from Saint Michael’s College in Vermont in 1997, and received his Ph.D. from the University of Massachusetts Medical School in 2002.  From 2002 to 2008 he conducted post-doctoral research at the Whitehead Institute for Biomedical Research in Cambridge MA with David Sabatini and support from the Damon Runyon Cancer Research Foundation and the Leukemia and Lymphoma Society.  In 2008 he became a Senior Research Associate with David Sabatini at the Whitehead Institute with support from the NIH/NCI Pathway to Independence Award.  He has been a member of the University of Massachusetts Medical School faculty since September 2009 in the Program in Molecular Medicine. In 2010, David Guertin was named a 2010 Pew Scholar in the Biomedical Sciences by the Pew Charitable Trusts.

        Mechanisms of Tissue Growth in Development and Disease

        We are interested in the mechanisms that regulatetissue growth and metabolism and their relevance to human diseases such ascancer, obesity, and diabetes.  There are basically 4 major building blocks(protein, carbohydrates, lipids, and nucleic acids) that must be both utilizedfor fuel and assembled into biomass in different compositions and amounts togenerate the vast array of cell and tissue types in the body.  We take a multidisciplinary approach, tryingto define the developmental paths that stem/progenitor cells follow to becoming a tissue and the signalsthat program metabolism and biomass production along the way.

        Figure1.  The mTOR pathway

        One specific area of interest is in elucidating the biochemical signals thatcontrol growth.  One particular growth regulator that interests us ismTOR, a protein kinase that assembles into at least two complexes.  mTORsenses intracellular nutritional state as well as systemic nutrients throughgrowth factor signaling pathways and uses this information to promote growth,proliferation, and survival.  We are interested in how mTOR does this andthe unique roles of each complex.

        A second area of interest is in defining developmental pathwaysthat give rise to important metabolic tissues, such as body fat.  Forexample, we recently discovered a mesodermal lineage that gives rise to some,but not all adipocytes.  The reason for this heterogeneity isunknown.  The developmental origins of adipocytes are still quitemysterious.  As obesity (a risk factor for diabetes, cardiovasculardisease, and cancer) has become a major medical challenge of this era,understanding adipocyte origins could help us fight this disease and itsassociated complications. 



        Rotation Projects

        We have several options for rotation projects in each of our interest areas.  Projects could include (1) studying mechanisms of how cells sense nutrients and growth factors and relay these signals to control tissue growth and metabolism; (2) studying stem/progenitor cells and the paths they take to becoming a tissue; or (3) how pathological changes to normal growth pathways cause human diseases such as cancer, obesity, and diabetes.
