Research Abstract |
Protein nanocages are self-organized complexes of oligomers whose three-dimensional architecture can been determined in detail. These structures possess nanoscale inner cavities into which a variety of molecules, including therapeutic or diagnostic agents, can be encapsulated. These properties yield these particles suitable for a new class of drug delivery carrier, or as a bioimaging reagent that might respond to biochemical signals in many different cellular processes. We report here the design, synthesis, and biological characterization of a Pancreatic cancer nanocage carrying small heat-shock protein. These nanoscale protein cages, with a targeting peptide on their surfaces, were prepared by genetic engineering techniques. iRGD-carrying nanocages showed lower cytotoxicity and significantly higher specificity for human pancreatic cancer cell lines than other cell lines in vitro.
