Summary
Epithelial-to-mesenchymal transition (EMT) drives cancer cell invasion, but most metastases are epithelial. A recent study reveals that E-cadherin, an epithelial marker, surprisingly promotes invasive ductal breast carcinoma metastasis by boosting tumor cell survival.
Area of Science:
- Oncology
- Cell Biology
- Cancer Metastasis Research
Background:
- Carcinoma cells gain mobility and invasiveness through epithelial-to-mesenchymal transition (EMT).
- However, a significant proportion of metastatic lesions retain an epithelial phenotype.
- The role of epithelial markers in promoting metastasis of epithelial-like tumors remains incompletely understood.
Purpose of the Study:
- To investigate the role of the epithelial marker E-cadherin in the metastasis of invasive ductal breast carcinoma.
- To elucidate the mechanisms by which E-cadherin influences tumor cell survival during metastasis.
Main Methods:
- Utilized models of invasive ductal breast carcinoma.
- Analyzed the expression and function of E-cadherin in metastatic processes.
- Assessed the impact of E-cadherin on tumor cell survival in vivo and in vitro.
Main Results:
- Demonstrated that E-cadherin expression is crucial for the metastatic potential of invasive ductal breast carcinoma.
- Showed that E-cadherin enhances the survival of carcinoma cells during the metastatic cascade.
- Challenged the traditional view of EMT as the sole driver of cancer cell mobility and invasiveness.
Conclusions:
- E-cadherin, a canonical epithelial marker, actively promotes breast cancer metastasis.
- The pro-metastatic function of E-cadherin is mediated by enhancing tumor cell survival, not solely by promoting EMT.
- Targeting E-cadherin could represent a novel therapeutic strategy for invasive ductal breast carcinoma.

01:19Cadherins in Tissue Organization
3.8K
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.

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.6K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

01:25Structure of Cadherins
4.6K
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...

6.3K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

02:38Mitogens and the Cell Cycle
7.6K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

3.0K
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
