E-cadherin as a tumor (invasion) suppressor gene
1Max-Delbrück-Center for Molecular Medicine, Berlin, Germany.
Summary
Diffuse-type gastric carcinomas exhibit reduced cell adhesion due to E-cadherin gene mutations. These mutations disrupt calcium-binding sites, significantly contributing to cancer development and poor patient survival.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Diffuse-type gastric carcinomas are characterized by decreased cellular adhesion.
- E-cadherin, a key cell adhesion molecule, is crucial for maintaining tissue integrity.
Purpose of the Study:
- To investigate the role of E-cadherin gene mutations in diffuse-type gastric carcinomas.
- To establish the link between E-cadherin alterations and cancer development and patient prognosis.
Main Methods:
- Analysis of E-cadherin gene mutations in diffuse-type gastric carcinoma samples.
- Evaluation of the impact of mutations on E-cadherin protein function, specifically calcium-binding sites.
Main Results:
- Approximately 50% of diffuse-type gastric carcinomas harbor mutations in the E-cadherin gene.
- These mutations lead to the destruction of critical calcium-binding sites within E-cadherin.
- Strong in vivo evidence supports the role of E-cadherin alterations in tumorigenesis.
Conclusions:
- Mutations in the E-cadherin gene are a significant factor in the pathogenesis of diffuse-type gastric carcinomas.
- E-cadherin alterations are strongly associated with the development of this cancer and reduced patient survival.

01:12Loss of Tumor Suppressor Gene Functions
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

01:25Structure of Cadherins
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This diversity of cadherins...
01:19Cadherins in Tissue Organization
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.
