Human uPAR, which focuses uPA to the tumor cell surface, thereby leading to extracellular matrix degradation and promoting metastasis of tumor cells, represents an attractive target for tumor therapy. Thus, the aim of the present study was to employ a mAb IIIF10-derived genetically engineered scFv to target the uPAR-uPA interaction. For this (i) plasmids should be constructed for the eukaryotic expression of mAb IIIF10-derived single chain antibody (scFv-IIIF10) in a soluble, secreted form or membrane-bound form, (ii) the binding properties of the scFv-IIIF10 should be analyzed in vitro, (iii) human ovarian cancer cells (OV-MZ-6#8) should be stably transfected with scFv-IIIF10-encoding expression plasmids and analysed for the effect on primary tumor growth and spread in a xenograft nude mouse model in comparison to the vector-transfected control.
