Summary
E-cadherin, a cell adhesion molecule, unexpectedly forms invadopodia, crucial for cancer invasion. This finding reveals new mechanisms in hybrid epithelial-mesenchymal transition and tumor spread.
Area of Science:
- Cell Biology
- Cancer Research
- Molecular Mechanisms
Background:
- Hybrid epithelial-mesenchymal (E/M) cells promote cancer invasion.
- The precise role of E-cadherin in cancer invasion remains incompletely understood.
- Invadopodia formation is an early and critical step in the cancer invasion process.
Purpose of the Study:
- To investigate the role of E-cadherin in invadopodia formation.
- To elucidate the molecular mechanisms underlying E-cadherin's involvement in invasion.
- To explore the significance of E-cadherin localization in hybrid E/M cells.
Main Methods:
- Utilized hybrid E/M cell lines, tissue sections, and patient-derived xenografts.
- Assessed E-cadherin's role in invadopodia using gelatin-FITC degradation assays.
- Employed proteomic analysis, siRNA, and proximity ligation assays for mechanistic studies.
Main Results:
- Demonstrated that E-cadherin is a critical component of invadopodia.
- Revealed synergistic trafficking of E-cadherin and MT1-MMP via a Rab vesicle-dependent pathway.
- Showed E-cadherin is essential for invadopodia structuration, interacting with key components like Arp2/3 and Cortactin.
Conclusions:
- E-cadherin's unexpected localization and function in invadopodia are vital for cancer cell invasion.
- This discovery offers new insights into the pro-invasive characteristics of hybrid E/M cells.
- E-cadherin's trans-adhesive properties are crucial for structuring invadopodia during tumor invasion.

Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

01:19Cadherins in Tissue Organization
2.9K
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.

01:25Structure of Cadherins
3.3K
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...

01:24Adherens Junctions
4.6K
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.

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.

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.2K
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.
