Moreover, the blockade of integrins using the fibronectin-related peptide GRGDSP (Gly-Arg-Gly-Asp-Ser-Pro) completely inhibited the growth and cell morphological alterations of prostate cancer PC-3 cells, confirming that integrins interact with the FNIII10 structural domain and play a key role in these processes (48, 49). The gene discussed is FN1; the disease is prostate carcinoma.
