Abstract:
The invention relates to methods for determining degree of integrin-mediated maintenance of cell invasive capacity of tumors, and to methods and compositions for inhibiting or preventing metastasis of cancers. In one aspect, the invention provides a method to determine degree of integrin-mediated maintenance of cell invasive capacity of epithelial derived tumors, particularly prostatic, breast, and lung cancers. In these regards, the invention relates to determining protein or mRNA of effectors of integrin-mediated maintenance of cell invasive capacity, particularly uteroglobin protein or mRNA, or to gauge degree of integrin-mediated maintenance of cell invasive capacity of prostatic, breast, or lung tumors. The invention also relates to methods and compositions, such as uteroglobin, which specifically bind to integrin and are effectors of integrin-mediated maintenance of tumor cell invasive capacity and thus inhibit metastasis.
