Abstract

Cell adhesion has an essential role in regulating metastasis, and loss of cell adhesion is a classic feature of invasion. There is currently a great deal of interest in the role of adhesion proteins and the antimetastatic protein nm23H1 in the progression of cancer. However, reports on the expression of these proteins in complete hydatidiform moles (CHMs) are limited. In the present study, expression of the adhesion molecules E-cadherin, P-cadherin, CD44, and CD44v6, and the antimetastatic protein nm23H1 was assessed in relation to the invasive potential of CHMs. This is the first report on the expression of these proteins in CHMs. Immunohistochemical assessment was carried out in CHMs (105 cases including 15 cases of invasive moles) and compared with that of gestational age-matched normal placentae (95 cases). The expression of the adhesion proteins ranged from mild to moderate intensity with a general down-regulation in the molar trophoblasts, the down-regulation in CD44 and CD44V6 being highly significant. No relation was, however, noticed with the invasiveness or the persistence of the disease. nm23H1 protein, on the other hand, was significantly down-regulated in the molar trophoblasts with none of the invasive lesions sho...Continue Reading

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins.

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.
