Increased expression of Cyr61 (CCN1) identified in peritoneal metastases from human pancreatic cancer

Abstract

The ECM protein Cyr61 shows increased expression in metastatic lesions in a clinically relevant model of pancreatic adenocarcinoma. Protein analysis confirms the microarray results and collocalization of Cyr61, and alpha(v) suggests that interaction between Cyr61 and alpha(v)beta(3) promotes formation of peritoneal metastases.
