Dose-dependent inhibition of 1,1′-dioctadecyl-3,3,3′,3′-tetramethylindocarbocyanine (DiI)-labeled (A) and acridine orange-labeled (B–G) DU-145 human prostate carcinoma cell adhesion to the endothelium by synthetic TF antigen-specific P30 peptide but not by control peptide (H). In B–H, numbers at the bottom indicate the concentration of the peptide tested. I and J, maximal inhibitory effect on adhesion of MDA-MB-435 human breast carcinoma (I) and DU-145 human prostate carcinoma (J) cells to the endothelium achievable with anti-TF antigen monoclonal antibody and P-30 peptide; bars, SD.
