Targeting Common but Complex Proteoglycans on Breast Cancer Cells and Stem Cells Using Evolutionary Refined Malaria Proteins
Abstract
In this project we have successfully produced recombinant 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. We have furthermore made proof-of-concept that a VAR2CSA protein conjugated with a toxin(hemiasterlin) efficiently eradicates breast cancer bone metastasis in a syngeneic mouse model. As such, all aims in this project has been fulfilled.
