Abstract

To explore the correlation between the expression of integrin subunits alpha5 and beta1 in prostate cancer (PCa) and its clinicopathological data including tumor grade and clinical stage. Expressions of integrin subunits alpha5 and beta1 were examined in 30 cases of PCa and 30 cases of normal prostatic tissues by immunohistochemical assay. Expressions of integrin subunits alpha5 and beta1 in PCa were lower than those in normal prostatic tissues (P <0.05) respectively. Compared with normal prostatic tissues, expressions of integrin subunits alpha5 and beta1 in PCa were rather weaker or even faded. Expressions of integrin subunits alpha5 and beta1 revealed an positive correlation with tumor's Gleason grade and negative with clinical TNM stage. The results indicate that integrin subunits alpha5 and beta1 have potential values in the diagnosis and are predictable indices in the proliferation of PCa.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
