title: Interview: from Down's syndrome to basic epigenetics and back again.
abstract: Dr Jeanne Lawrence talks to Caroline Telfer, Commissioning Editor. Dr Jeanne Lawrence is an internationally recognized leader in the study of chromosome regulation by noncoding RNA and nuclear and genome organization. Her research bridges fundamental questions about genome regulation with clinical implications of recent advances in epigenetics. Her interest in chromosome structure and regulation has been a theme throughout her career and she has been honored for her work developing sensitive FISH technology for the detection of single copy genes, as well as RNAs. Her laboratory's publications include the initial demonstration of cell type-specific gene organization with nuclear subdomains; the novel biology of a noncoding RNA, XIST, which coats a whole X-chromosome to induce its silencing; and a new architectural role for a large noncoding RNA to scaffold a nuclear body. Her laboratory's work on epigenetic chromosome regulation in stem cells led to recent studies regarding unanticipated roles of repeat sequences in normal chromosome regulation and deregulation in cancer. Most recently, her laboratory has demonstrated a new approach to translate the basic mechanism of X-chromosome inactivation to correct a chromosomal dosage imbalance in patient-derived cells with trisomy 21 (Down's syndrome). Dr Lawrence has received awards from numerous agencies, including a Research Career Development Award from the National Center for Human Genome Research, career awards from the American Society of Cell Biology, the German Society for Biochemistry, the Muscular Dystrophy Association and a John Merck Fund Translational Research Award. She has served on the NIH National Advisory Council for Human Genome Research, numerous study sections and is currently a monitoring editor for the Journal of Cell Biology. Dr Lawrence has a BA in Biology and Music from Stephens College (MO, USA), a MS in Human Genetics and Genetic Counseling from Rutgers University (NJ, USA) and a PhD in Developmental Biology from Brown University (RI, USA). She is currently a Professor and Interim Chair of the Department of Cell and Developmental Biology at the University of Massachusetts Medical School (MA, USA).
