Summary
Epidermal growth factor receptor (EGFR) destabilizes E-cadherin adhesion, promoting cancer. E-cadherin loss also fuels cancer by activating EGFR, impacting cell movement and growth.
Area of Science:
- Cell Biology
- Molecular Biology
- Cancer Research
Background:
- Epidermal growth factor receptor (EGFR) and E-cadherin are key regulators of epithelial cell behavior.
- Dysfunctional EGFR and E-cadherin are implicated in various cancers.
- These proteins have reciprocal interactions influencing cell proliferation, differentiation, and adhesion.
Purpose of the Study:
- To review the molecular and cellular mechanisms governing the cross-talk between EGFR and E-cadherin.
- To highlight the role of endocytosis in the EGFR-E-cadherin feedback loop.
- To discuss the relevance of this interaction in tissue morphogenesis, homeostasis, and cancer progression.
Main Methods:
- Literature review of molecular and cellular mechanisms.
- Analysis of cross-talk between EGFR and E-cadherin.
- Focus on the role of endocytosis in their feedback loop.
Main Results:
- EGFR destabilizes E-cadherin by promoting its endocytosis, altering cytoskeletal interactions, and reducing expression, thereby promoting tumorigenesis.
- Loss or mutations in E-cadherin lead to uncontrolled EGFR activation, enhancing cancer cell invasion, motility, and altered endocytosis.
- Endocytosis plays a critical role in mediating the feedback between EGFR and E-cadherin.
Conclusions:
- The intricate cross-talk between EGFR and E-cadherin, particularly involving endocytosis, is crucial for tissue homeostasis.
- Disruptions in this EGFR-E-cadherin axis significantly contribute to cancer development and progression.
- Understanding these mechanisms offers insights into potential therapeutic strategies for epithelial malignancies.

01:19Cadherins in Tissue Organization
3.2K
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
2.3K
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
3.6K
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...

02:38Mitogens and the Cell Cycle
7.0K
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...

01:24Adherens Junctions
5.2K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

4.1K
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...
