Focal Adhesion Proteins α- and β-Parvin are Overexpressed in Human Colorectal Cancer and Correlate with Tumor Progression.

This study aims to address the role of focal adhesion proteins α- and β-parvin in human colorectal carcinoma (CRC). Expression of α- and β-parvin was examined by immunohistochemistry and real-time RT-PCR in a series of human CRC. Parvins were overexpressed in CRC and their expression correlated significantly with tumor invasion, lymph node metastasis, and disease stage. A significant positive correlation of parvins protein expression with overexpression of integrin-linked kinase, p-AKT, and nuclear β-catenin, as well as with downregulation of E-cadherin was also observed. In conclusion, overexpression of α- and β-parvin seems to be implicated in human colorectal cancer progression.
