Complex cadherin expression in human prostate cancer cells.

Changes in cell-cell interactions are critical in the process of cancer progression. Likewise, it has been shown that loss of expression of the cell adhesion molecule E-cadherin is associated with grade, stage, and prognosis in many carcinomas, including prostate cancer. Impaired E-cadherin-mediated interactions result in an invasive phenotype; however, the mere loss of cell-cell contact and communication is not the sole explanation for the observed correlation between loss of E-cadherin-mediated adhesion and poor clinical outcome. Using a degenerate cloning strategy for sequences that are highly conserved between the various cadherins, we found several other cadherins (N- and P-cadherin and cadherin-4, -6, and -11) to be expressed in human prostate cancer cells. Our data suggest that besides loss of E-cadherin function, also (upregulation of) expression of other cadherins is involved in the acquisition of an invasive and/or metastatic phenotype. Especially, changes in the expression of N-cadherin and cadherin-11 may play an important role in prostate cancer progression.
