Prostatic carcinoma cell migration via alpha(v)beta3 integrin is modulated by a focal adhesion kinase pathway.


The highly invasive human prostate cancer PC3 cell line was found to express the alpha(v)beta3 integrin; in contrast, the noninvasive LNCaP prostate cancer cell line did not express alpha(v)beta3. PC3 cells adhered to and migrated on vitronectin (VN), an alpha(v)beta3 ligand expressed in mature bone where prostate cancer cells preferentially metastasize. In… (More)
