The role of E-cadherin - 160C/A polymorphism in breast cancer

Breast cancer is the most prevalent cancer in women worldwide. Numerous studies have suggested that the E-cadherin adhesion system is dysregulated in cancer cells. These impaired functions of E-cadherin contribute to releasing cancer cells from the primary lesion to cell dedifferentiation. Some studies have shown that polymorphism may affect E-cadherin expression, and then play a role in susceptibility to breast cancer. However, the results remained controversial. In this short review, we summarize the functions of E-cadherin and the signaling pathways it regulates, and assess the association between CDH1 polymorphisms and breast cancer susceptibility. This study suggests that genetic variation in CDH1 and -160C/A polymorphism may have an association with breast cancer risk. The assessment of CDH1 polymorphisms may be used for the identification of patients suitable for anti- CDH1 therapy.
