Biomarker Research volume 9 , Article number: 44 Cite this article. Metrics details. To systematically determine E-Cadherin protein expression in normal and cancerous tissues, 14, tumor samples from different tumor types and subtypes as well as samples of 76 different normal tissue types were analyzed by immunohistochemistry in a tissue microarray format. E-Cadherin was strongly expressed in normal epithelial cells of most organs. From 77 tumor entities derived from cell types normally positive for E-Cadherin, 35 Tumors with the highest rates of E-Cadherin loss included Merkel cell carcinoma, anaplastic thyroid carcinoma, lobular carcinoma of the breast, and sarcomatoid and small cell neuroendocrine carcinomas of the urinary bladder.

E-cadherin

Cadherins named for "calcium-dependent adhesion" are cell adhesion molecules important in forming adherens junctions that let cells adhere to each other. Cell-cell adhesion is mediated by extracellular cadherin domains, whereas the intracellular cytoplasmic tail associates with numerous adaptors and signaling proteins, collectively referred to as the cadherin adhesome. The cadherin family is essential in maintaining cell-cell contact and regulating cytoskeletal complexes. The cadherin superfamily includes cadherins, protocadherins , desmogleins , desmocollins , and more. There are multiple classes of cadherin molecules, each designated with a prefix for tissues with which it associates. Classical cadherins maintain the tone of tissues by forming a homodimer in cis while desmosomal cadherins are heterodimeric. Although classical cadherins take a role in cell layer formation and structure formation, desmosomal cadherins focus on resisting cell damage. Desmosomal cadherins maintain the function of desmosomes that is to overturn the mechanical stress of the tissues. Similar to classical cadherins, desmosomal cadherins have a single transmembrane domain, five EC repeats, and an intracellular domain. There are two types of desmosomal cadherins: desmogleins and desmocollins. These contain an intracellular anchor and cadherin like sequence ICS. The major function of desmoplakins is to bind to intermediate filament by interacting with plakoglobin, which attach to the ICS of desmogleins, desmocollins and plakophilins.

In contrast, most mutations found in e-cadherin lobular breast cancers were out-of-frame mutations, which yield secreted truncated E-cadherin products.

The calcium-dependent interactions among E-cadherin molecules are critical for the formation and maintenance of adherent junctions in areas of epithelial cell-cell contact. Loss of E-cadherin-mediated-adhesion characterises the transition from benign lesions to invasive, metastatic cancer. Nevertheless, there is evidence that E-cadherins may also play a role in the wnt signal transduction pathway, together with other key molecules involved in it, such as beta-catenins and adenomatous poliposis coli gene products. The structure and function of E-cadherin, gene and protein, in normal as well as in tumor cells are reviewed in this paper.

In epithelial cells, E-cadherin-containing cell-to-cell junctions are often adjacent to actin-containing filaments of the cytoskeleton. Human Mutation. Conversely, decreasing cell density decreasing cell-cell adhesion or applying mechanical stretch to place E-cadherins under increased tension promotes cell cycle entry and YAP nuclear localization.

Pathological differential diagnosis of solid-pseudopapillary neoplasm and endocrine tumors of the pancreas. The Journal of Cell Biology. This in turn may allow cancer cells to cross the basement membrane and invade surrounding tissues. Goldstein NS. Since the ret gene lacks matching of the splice sites to the CDH1 gene, this might be the explanation. Loss of E-cadherin alone cannot be a predictor of metastatic potential and negative outcome as E-cadherin is lost even in the pre-invasive stages of LCIS and atypical lobular hyperplasia. E-Cadherin immunostaining and patient prognosis. Loss of E-cadherin has been demonstrated in invasive lobular carcinoma of the breast, but the relationship between E-cadherin expression and breast cancer histopathology and prognosis is less clear. Epithelial-mesenchymal conversion is also observed in malignant tumors of epithelial origin.

CDH1 has also been designated as CD cluster of differentiation It is a tumor suppressor gene. The discovery of cadherin cell-cell adhesion proteins is attributed to Masatoshi Takeichi, whose experience with adhering epithelial cells began in

Tumor suppressor genes and Oncogenes. Physiologically, branching is an important feature that allows tissues, such as salivary glands and pancreatic buds, to maximize functional surface areas. E-cadherin immunostaining can be used in finding patients with favorable outcomes among node-positive patients. E-cadherin null mutant embryos fail to form a trophectoderm epithelium. The Breast. Loss of E-cadherin is a sensitive and relatively specific biomarker to confirm a diagnosis of ILC and its variants. Simultaneous loss of E-cadherin and catenins in invasive lobular breast cancer and lobular carcinoma in situ. A negative E-cadherin stain was a sensitive and specific biomarker to confirm the diagnosis of invasive lobular carcinoma specificity This network is better equipped to maintain tissue integrity if under intercellular stress, but should not be considered a static system.
