摘要
Vascular proteins expressed at liver metastasis sites could serve as prognostic markers or as targets for pharmacodelivery applications. We employed a proteomic approach to define such proteins in three syngeneic mouse models of liver metastasis. Vascular structures were biotinylated in vivo by a terminal perfusion technique, followed by mass spectrometric analysis of accessible biotinylated proteins. In this manner, we identified 12 proteins for which expression was selectively associated with liver metastasis, confirming this association by tissue immunofluorescence or in vivo localization with radiolabeled antibodies. In summary, our findings identify vascular proteins that may have prognostic or drug-targeting use in addressing liver metastases, a common issue in many advanced cancers. Cancer Res; 70(1); 309-18.
