Dr. Beliveau [HHMI Fellow] is using newly developed “super-resolution” microscopy methods to look at DNA structure in cells. These new methods may provide a clearer picture of the difference between the structure of genes that are “on” and genes that are “off.” As many cancers are driven by the abnormal expression of genes such as oncogenes and tumor suppressors, information about how DNA structure can turn genes on and off may aid in the development of cancer therapies.
