Abstract

Nectin-4 is a member of the Nectin family of four Ca(+)-independent immunoglobulin-like cell adhesion molecules and implicated in cell adhesion, movement, proliferation, differentiation, polarization, and survival. The aberrant expression of Nectin-4 has been found in a variety of tumors; however, its expression in hepatocellular carcinoma (HCC) is still poorly understood. This study was to investigate the expression of Nectin-4 and its clinical significance in the patients with HCC. The expression of Nectin-4 was assessed at mRNA and protein levels by quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blotting assays in 20 HCC specimens and adjacent non-tumor live tissues. Furthermore, the clinical significance of Nectin-4 in 87 cases of HCC was confirmed by immunohistochemistry. The mRNA and protein levels of Nectin-4 were higher in HCC tumor tissues than in the matched non-tumor tissues. Nectin-4 was located in the cytoplasm of tumor cells and over-expressed in 67.82% (59/87) HCC tissues by immunohistochemical staining. Positive Nectin-4 expression was significantly correlated with tumor size (P=0.029), status of metastasis (P=0.023), vascular invasion (P=0.018) and tumor-node-metastasis stage...Continue Reading

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.
