fVII targeting enhances the therapeutic effect of VP PDT for human and mouse breast cancer cells. A and B. fVII targeting decreased the EC50 (crossing with dotted lines) concentration of VP in fVII-tPDT by three to four fold for human (MDA-MB-231) (A) and mouse (EMT6) (B) breast cancer lines, compared to ntPDT (689 nm laser for 60 J/cm2). C. fVII targeting also decreased the EC50 (crossing with dotted line) of the laser energy for VP PDT (2 μM VP). D. The effect of fVII-targeted VP PDT (2 μM VP, 689 nm laser for 60 J/cm2) could be inhibited by unconjugated mfVII. Results in A-C are representative of two experiments.
