Cadherins as novel targets for anti-cancer therapy.

The cell adhesion molecules N-, VE- and OB-cadherin have been implicated as regulators of tumor growth and metastasis. We discuss evidence that N- and VE-cadherin play a key role in promoting blood vessel formation and stability, processes which are essential for tumor growth. Secondly, we describe the potential involvement of N- and OB-cadherin in the metastatic process. Finally, studies concerning the effects of the N-cadherin antagonist designated ADH-1 on tumor growth are presented. Collectively, these observations suggest that antagonists of N-, VE- and OB-cadherin would be useful as anti-cancer agents.
