dc.description.abstract | E-cadherin, beta-catenin, and beta 1 integrin are important cell adhesion molecules to maintain epithelial structure and function. We investigated the expression of these cell adhesion molecules in cholesteatomas to understand the role of cell-cell and cell-extracellular matrix interaction in cholesteatomas. An immunohistochemical investigation was carried out on 35 cholesteatoma tissue samples (14 congenital, 21 acquired cholesteatomas) and 10 normal retroauricular skin (RAS) tissues which are obtained during middle ear surgery. The expression rate was measured to find out differences between retroauricular skin and cholesteatoma, as well as between congenital and acquired cholesteatoma. E-cadherin expression rate was significantly lower in the cholesteatoma (spinous layer 88.7 +/- A 17.9 %, granular layer 54.6 +/- A 22.6 %) than in the RAS (100 %, 74.4 +/- A 7.4 %) and in the acquired (83.3 +/- A 19.4 %, 48.1 +/- A 22.9 %) than in the congenital (96.7 +/- A 12.0 %, 64.4 +/- A 18.8 %). beta-catenin expression rate was significantly lower in the cholesteatoma (spinous layer 84.1 +/- A 17.2 %, granular layer 28.7 +/- A 30.8 %) than in the RAS (100 %, 75.9 +/- A 6.1 %) and in the acquired (78.1 +/- A 17.0 %, 17.1 +/- A 22.3 %) than in the congenital (93.2 +/- A 13.5 %, 46.1 +/- A 34.2 %). The expression pattern of beta-catenin is similar to that of E-cadherin. In beta 1 integrin, there was no significant difference of the expression rate between RAS and cholesteatoma, as well as between congenital and acquired cholesteatoma. In conclusion, the expression of E-cadherin and beta-catenin is reduced in cholesteatoma, and the reduction is more pronounced in acquired cholesteatoma than in congenital cholesteatoma. Acquired cholesteatomas showed more aggressive characteristics than congenital cholesteatomas in terms of cell-cell adhesion. | en_US |
