Tissue and cell targeting are crucial to maximize therapeutic efficacy and limit off-targeting effects. Simultaneously, improved control over subcellular processing/trafficking, especially in the context of the /in vivo/ environment, has been identified as an absolutely critical hurdle. The broad goal of our work is to develop simple strategies for targeted and efficient delivery within remodeling tissues. Tissue repair and extracellular matrix (ECM) turnover are profoundly important in a variety of pathological processes, including hypertension, restenosis, fibrosis, and cancer. Thus, because successful delivery materials must selectively partition into these tissues and enter diseased cells, our approach is to exploit natural ECM remodeling processes for delivery into diseased tissues. To that end, we have developed new methods for the presentation of cell-targeting peptides that rely on the natural upregulation of proteins involved in cellular migration and ECM turnover to facilitate utilization. Results demonstrating matrix metalloproteinase (MMP)-1/2-responsive nucleic acid targeting and delivery will be presented. Work on the coupling of cell targeting with programmed subcellular trafficking and processing will also be presented, including recent studies demonstrating the efficacy of histone-derived peptides to enhance nuclear delivery and processing of DNA. Persons with disabilities have the right to request and receive reasonable accommodation. Please call the Department of Chemical Engineering and Materials Science at 355-5135 at least one day prior to the seminar; requests received after this date will be met when possible. -- Lauren Brown Graduate Program Secretary Michigan State University Department of Chemical Engineering and Materials Science 2527 Engineering Building East Lansing MI 48864 (517)355-5135 ph.
