What does E-cadherin do in cancer?
Homophilic E-cadherin binding between cells is important in mediating contact inhibition of proliferation when cells reach confluence. Loss of E-cadherin expression results in loss of contact inhibition and is associated with increased cell motility and advanced stages of cancer.
What does E-cadherin positive mean?
Data from model systems suggest that E-cadherin is a potent invasion/tumor suppressor of breast cancer. Consistent with this role in breast cancer progression, partial or complete loss of E-cadherin expression has been found to correlate with poor prognosis in breast cancer patients.
Is E-cadherin a tumor suppressor?
E-cadherin is a tumor suppressor protein with a well-established role in cell–cell adhesion. Adhesion could contribute to tumor suppression either by physically joining cells or by facilitating other juxtacrine signaling events.
Where is e-cadherin expressed?
Introduction. The E-cadherin protein (encoded by the CDH1 gene) is normally expressed in breast epithelial tissue and functions as a critical part of epithelial cell adhesion and epithelial-to-mesenchymal transition (EMT)1,2,3.
What is E-cadherin a marker for?
Discussion. E-cadherin is a cell adhesion molecule that is expressed in normal breast tissue and is useful as a phenotypic marker in breast cancer, with absence of its expression frequently observed in lobular type tumors.
What is E-cadherin positive?
E-cadherin is a cell adhesion molecule that is expressed in normal breast tissue and is useful as a phenotypic marker in breast cancer, with absence of its expression frequently observed in lobular type tumors.
What is E-cadherin test?
E-cadherin is a test that the pathologist might use to help determine if the tumor is ductal or lobular. (The cells in invasive lobular carcinomas are often negative for E-cadherin.) If your report does not mention E-cadherin, it means that this test was not needed to tell what type of cancer you have.
What does E cadherin positive mean?
