Summary
Cellular contractility and cytoskeletal regulation control tissue tension. Dysregulation of this tension pattern can lead to oncogenic cell extrusion, a process relevant to cancer.
Area of Science:
- Cell Biology
- Biophysics
- Cancer Biology
Background:
- Cellular contractility is crucial for tissue cohesion and morphogenesis.
- E-cadherin mediated adhesion links contractile cell cortices, transmitting tension across epithelia.
- Contractility is patterned along the apical-lateral axis within epithelial junctions.
Purpose of the Study:
- To detail the actomyosin cytoskeleton organization during oncogenic cell extrusion.
- To discuss the implications of cell extrusion in cancer.
Main Methods:
- Analysis of actomyosin cytoskeleton organization.
- Investigation of intra-junctional tension regulation by cytoskeletal elements.
Main Results:
- Cytoskeletal regulation controls intra-junctional tension levels.
- Apicolateral tension patterning is essential for normal epithelial function.
- Dysregulation of apicolateral tension drives oncogenic cell extrusion.
Conclusions:
- The actomyosin cytoskeleton plays a key role in regulating epithelial tension.
- Aberrant tension patterns, particularly along the apical-lateral axis, can promote cancer progression through cell extrusion.
- Understanding these mechanisms is vital for cancer research and therapeutic development.

01:19Cadherins in Tissue Organization
4.6K
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.

01:35Cancer Cell Migration through Invadopodia
3.5K
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,...

01:16Cell Motility through Blebbing
2.8K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

01:26Tension Response at Adherens Junctions
4.3K
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.

01:13Cell-matrix's Response to Mechanical Forces
3.8K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.

01:19Cell Migration
7.6K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.
