We have successfully produced recombinant malaria derived VAR2CSA that binds with high affinity and high specificity to breast cancer cells and breast cancer tissue biopsies. We have demonstrated that the protein binds to distinct secondary modified proteoglycans exclusively present on breast cancer cells and that targeting these with recombinant VAR2CSAinterferes with key functions of the cancer cell like growth, migration and invasion. In vivo models demonstrate that conjugation of a toxin to VAR2CSA followed by IV administration to metastatic breast cancer bearing mice completely cures the animals.
