The HER2/neu receptor is over-expressed on the surface of many types of cancer cells, and is widely used for targeted delivery of anticancer drugs. We have created genetically engineered construct expressing the PE40 fragment of Pseudomonas toxin bound with the DARPin molecule which recognizes the HER2/neu receptor with high specificity. The construct destroyed transfected tumor cells in vitro. Intra-Tumor injections of the construct complexed with polyethyleneimine led to growth retardation of D2F2/E2 tumors in mice. These results suggest a possibility of using this approach to develop new anticancer drugs.
