Research in Dr. Rice's laboratory focuses on the development of non-viral targeted gene delivery. The main emphasis is on designing low molecular weight glycopeptide and polyethylene glycol peptide carrier molecules that, when combined with plasmid DNA, spontaneously form colloidal particles. When dosed intravenously, these particles target mammalian lectins on the hepatocyte or Kupffer cell surface and, once internalized into these cells, mediate transient gene expression. The primary goal of research in the Rice laboratory is to design carrier molecules capable of controlling the level and duration of gene expression, with the aim of applying this knowledge toward a variety of therapeutic interventions. More recently, his group has applied these carriers to delivery of siRNA and shRNA expression cassettes in vivo and used biophotonic imaging to assess the levels of knockdown efficiency of the various delivery systems.
