Janice M. Burke, PhD has used cells cultured from the human retinal pigment epithelium (RPE) for many years to study basic features of the structure and function of these cells. Her current major interests are in determining how the RPE develops and maintains its characteristic cell shape, and in identifying how aging may reduce the effectiveness of the RPE as a supporting layer for retinal photoreceptors. These two areas are particularly timely. Transplantation of the RPE is being developed by others to treat degenerative diseases of the retina, such as age-related macular degeneration. However, one impediment to transplantation is producing donor RPE tissue in which the cells develop and retain their normal, highly-regular cell phenotype. Dr. Burke has determined that a major molecular determinant of cell shape, cellular adhesion, is altered by the very dissociation process used to produce tissue for transplantation, and most RPE cells fail to restore their shape even after months. The next step, which is a significant challenge, is to identify the molecular pathways which regulate the formation of adhesions in RPE cells so that cell shape recovery can be accelerated and induced to occur in a higher proportion of cells.
Dr. Burke is also the principal investigator on a Core Grant for Vision Research from the National Eye Institute that helps to support the research activities of several investigators at MCW who study the eye and visual system.
