Inhibition of experimental metastasis of murine fibrosarcoma cells by oligopeptide analogues to the fibronectin cell-binding site.

We have analyzed the effect of the synthetic oligopeptides Gly-Arg-Gly-Asp-Ser-Pro (GRGDSP) and Gly-Arg-Gly-Glu-Ser-Pro (GRGESP), analogues to the fibronectin cell-binding sequence, on the formation of experimental lung metastasis. SR-BALB were injected alone or in conjunction with GRGDSP or GRGESP in the tail vein of BALB/c mice. Co-injection with GRGESP reduced by approximately 70% the number of metastatic colonies per mouse. However, co-injection with the closely related peptide GRGDSP, containing the conservative substitution Glu/Asp, did not affect metastatic behavior. GRGESP peptide anti-metastatic activity was not due to a toxic effect on tumor cells or on mice. In vitro adhesion assays testing for a possible effect of the peptide on cell-matrix interactions indicated that the GRGESP peptide did not affect cell adhesion to the matrix proteins tested.[1]
