Main Interests: Our laboratory is studying the epigenetic basis of disease, including cancer, autism, and psychiatric illness. Epigenetics involves changes in DNA and chromatin structure that are remembered by the cell when it divides, such as DNA methylation, genomic imprinting, and histone modification. Epigenetics is important because many of the differences between a germ cell and a somatic cell, or two different tissue types, or a cancer and a normal cell, involve epigenetic changes rather than mutation in the DNA sequence. Early work from our group involved the discovery of specific alterations in DNA methylation in cancer, as well as common epigenetic (methylation and imprinting) variants in the population that may be responsible for a significant population-attributable risk of cancer. This has led to a major cancer epigenetics translational study to introduce epigenetic testing for cancer risk into the general medical setting. We are also investigating the molecular basis of Beckwith Wiedemann syndrome (BWS), the paradigm of cancer-predisposing disorders caused by an epigenetic mechanism, uncovering the first antisense RNA associated with human disease. In addition, we found that BWS is linked to in vitro fertilization technology. Recently we have developed a mouse model of loss of imprinting in cancer, in which we have found that epigenetic alterations in stem cells increase the risk of malignancy, and suggest an epigenetic progenitor origin of human cancer. We are also pioneering genome-wide technolgy for epigenetics research. We have been awarded a Center of Excellence in Genome Sciences (CEGS) from the NIH, to develop novel tools for genome-wide epigenetic analysis, applicable to disease generally. Work in the CEGS is an interdisciplinary collaboration involving investigators in the Schools of Medicine and Public Health, as well as the Icelandic Heart Association. We are applying these tools to common diseases, including bipolar disorder and autism. We are developing tools to investigate methylation, allele-specific gene expression, and chromatin modification genome-wide, and we are developing new quantitative tools for epigenome analysis. | ||
