Theodor Boveri in 1914 recognized the significance of changes in the adhesion of tumor cells to the development of cancer. Cell adhesion is essential in all aspects of in verte-brate cells such as cell growth, cell migration and cell differentiation. The majority of adhesion molecules fall into one of four families: cadherins, integrins, immunoglobulin superfamily (IgSF) and selectins. The cadherins are a family of homophilic CAMs (cell adhesion moleculs), Ca2+ dependent. The most important members of cadherins are E-cadherins (epithelial), P-cadherins (placental) and N-cadherins (neural). Immunoglobu-lin superfamily CAMs (IgSF CAMs) are either homophilic or heterophilic and bind in-tegrins, growth factor receptors cadherins or different IgSF CAMs. The integrins are a family of heterophilic CAMs that bind IgSF CAMs or the extracellular matrix. The se-lectins are a family of heterophilic CAMs that bind fucosylated carbohydrates, e.g. mu-cins. They are calcium-dependent. The three family members are E-selectin (endothelial (, L-selectin (leukocyte) and P-selectin (platelet). Recent experimental results indicate that, as well as mediating intercellular and cell–matrix interactions, cell-adhesion mole-cules also directly modulate signal transduction. Changes in the expression or function of cell-adhesion molecules can therefore contribute to tumor progression via altering the adhesion status of the cell or affecting cell signaling. The ability to colonize a specific organ has been correlated with the preferential adhesion of the cancer cells to endotheli-al cells derived from the target organ. This review summarizes recent findings about role of adhesion molecules in the tumor progression.
