Dr. Pellman received his MD in 1986 from the University of Chicago, Pritzker School of Medicine, and did postgraduate training in pediatrics and pediatric hematology-oncology at DFCI and Children's Hospital, Boston. He was a postdoctoral fellow at the Whitehead Institute for Biomedical Research at Massachusetts Institute of Technology. In 1995, he joined DFCI, and is currently the Margaret M. Dyson Professor of Pediatric Oncology, Professor of Cell Biology, Harvard Medical School

ResearchCell Division and Genome Stability
Our laboratory works on cell biology topics in two interrelated areas: cytoskeletal regulation and the control of genome stability. We take a range of approaches including genetics, functional genomics, biochemistry and live cell imaging. There are ongoing projects using yeast, tissue culture cells, and genetically engineered mice.
Our work on cytoskeletal dynamics is focused on the mechanism of chromosome segregation in normal cells and cancer cells. We are particularly interested in how the microtubule and actin cytoskeletons interact and how cell cycle signals remodel these cytoskeletal systems. For example, we have recently uncovered a mechanism by which actin organization and the adhesive microenvironment of cells influence chromosome segregation. We have defined cytoskeletal mechanisms that control polarized cell growth, asymmetric cell division, and cytokinesis. We use biochemical and imaging approaches to understand these processes at a mechanistic level.
We are also interested in how aneuploidy (abnormal chomosome number) and polyoidy (increased sets of chromosomes) impact on tumor biology. We recently found that failure of cytokinesis, which doubles the number of chromosomes and centrosomes, promotes tumorigenesis in a mouse breast cancer model. We are defining the consequences of having extra centrosomes in cancer cells. We are using yeast to ask whether aneuploidy or polyploidy can affect the rate of adaptation (evolution). We have developed methods to generate human cells with specific cancer-associated trisomies.
