title: Defective E-cadherin function in urological cancers: clinical implications and molecular mechanisms.
abstract: Decreased E-cadherin expression assessed by immunohistochemistry correlates with poor survival of bladder and prostate cancer patients. The clinical usefulness of this parameter should therefore be evaluated in a large-scale prospective study. E-cadherin is an epithelial cell-cell adhesion molecule and impaired function presumably leads to increased invasive capacity of the cells. It has been shown that defective function can result from several mechanisms: mutation of the gene, alteration of transcription, posttranslational modification or changes in the interaction of E-cadherin with cytoskeleton anchoring proteins--the catenins. A major mechanism leading to decreased E-cadherin expression in tumors lies in decreased transcription of the gene. Hence, a better understanding of the regulation of E-cadherin transcription might open avenues for therapy by restoring normal expression.
