    The role of cadherin/catenin complex in malignant melanoma

    No full text
    In the present review article the role of cadherin/catenin complex in cases of malignant melanoma is discussed in some detail. Cadherins represent the most important superfamily of adhesion molecules with epithelial E-cadherin being the most studied. Its role in normal state as well as in cancer invasion and metastasis and some other pathologies is crucial. E-cadherin expression is altered in malignant melanomas and its downregulation or absence is associated with melanoma invasion and metastasis potential. A shift from E-cadherin expression to neural N-cadherin expression in melanocytes is also detected in malignant melanomas formation. In addition, a discussion regarding the role of placental P-cadherin and vascular endothelial VE-cadherin as well as the recently identified molecule of dysadherin, is attempted in brief.Π’ ΠΎΠ±Π·ΠΎΡ€Π΅ обсуТдаСтся Ρ€ΠΎΠ»ΡŒ ΠΊΠ°Π΄Π³Π΅Ρ€ΠΈΠ½/ΠΊΠ°Ρ‚Π΅Π½ΠΈΠ½ΠΎΠ²ΠΎΠ³ΠΎ комплСкса ΠΏΡ€ΠΈ злокачСствСнной ΠΌΠ΅Π»Π°Π½ΠΎΠΌΠ΅.
