  • Title: Triflavin, an Arg-Gly-Asp-Containing Peptide, Inhibits B16-F10 Mouse Melanoma Cell Adhesion to Matrix Proteins via Direct Binding to Tumor Cells.
    Author: Sheu JR, Huang TF.
    Journal: J Biomed Sci; 1996; 3(5):359-364. PubMed ID: 11725118.
    Abstract:
    Triflavin, an Arg-Gly-Asp (RGD)-containing snake venom peptide, inhibits B16-F10 mouse melanoma cell adhesion to extracellular matrices, e.g. fibronectin, vitronectin, fibrinogen, and collagen type I. In this study, GRGDS inhibits B16-F10 mouse melanoma cell adhesion to immobilized triflavin in a dose-dependent manner. In addition, flow-cytometric analysis and the fluorescence staining method in which FITC-triflavin is utilized as a binding ligand were used. GRGDS inhibits the binding of FITC-triflavin to B16-F10 cells. Additionally, the above results suggest that triflavin directly binds to its receptors expressed on B16-F10 cell surface primarily via its RGD sequence, thereby inhibiting B16-F10 cell adhesion to extracellular matrices.
