YAP forces fibroblasts to feel the tension
Nature Cell Biology
|June 4, 2013
Summary
Cancer-associated fibroblasts (CAFs) activate through tissue tension, promoting cancer progression. YAP is identified as a key tension-stimulated CAF activator, creating a mechanically reinforced loop that enhances malignancy.
Area of Science:
- Oncology
- Biophysics
- Cell Biology
Background:
- Cancer-associated fibroblasts (CAFs) contribute to tumor progression through extracellular matrix (ECM) deposition and remodeling, influencing tissue tension.
- The precise mechanisms of CAF activation and their specific roles in tumor mechanics remain incompletely understood.
- Investigating the interplay between mechanical forces and cellular behavior within the tumor microenvironment is crucial.
Discussion:
- YAP signaling is identified as a critical mediator of CAF activation in response to mechanical tension.
- This activation establishes a mechanically reinforced feed-forward loop, where increased ECM deposition further enhances tissue tension and CAF activity.
- The YAP-driven CAF activation pathway represents a novel mechanism linking mechanical cues to cancer progression.
Key Insights:
- YAP acts as a tension-stimulated activator of cancer-associated fibroblasts (CAFs).
- Mechanical forces, through YAP, drive CAF-mediated ECM remodeling, promoting a pro-malignancy microenvironment.
- A positive feedback loop between tissue tension and CAF activation, mediated by YAP, accelerates cancer progression.
Outlook:
- Targeting the YAP-mediated CAF activation pathway could offer novel therapeutic strategies for cancers.
- Further research into the biophysical regulation of the tumor microenvironment is warranted.
- Understanding these mechanical feedback loops is essential for developing effective anti-cancer therapies.

01:13Cell-matrix's Response to Mechanical Forces
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.

01:09Introduction to Fibroblasts
Rudolph Virchow discovered spindle-shaped cells called fibroblasts in 1858. Inactive fibroblasts, called fibrocytes, become activated by various stimuli, such as growth factors and inflammatory cytokines. Activated fibroblasts play a crucial role in wound healing, inflammation, formation of new blood vessels, and cancer progression. Uncontrolled activation of fibroblasts results in fibrosis, the excess deposition of fibrous tissue, which can lead to scarring and affect normal organs. This...
01:25Fibronectins Connect Cells with ECM
Fibronectin is an adhesive glycoprotein present in the extracellular matrix of embryogenic and adult tissue. These molecules primarily aid in regulating cell motility and attachment. A fibronectin molecule is composed of two identical polypeptide chains attached to each other by a pair of disulfide bonds at the C-terminal.
Both proteoglycans and collagen are attached to fibronectin proteins, which, in turn, are attached to integrin proteins. These integrin proteins interact with transmembrane...

01:17Intracellular Signaling Affects Focal Adhesions
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

01:26Tension Response at Adherens Junctions
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.

01:21Layers of Connective Tissue Proper
Fascia, a thin layer of fibrous connective tissue, is distributed throughout the body. It demarcates and forms a supportive covering over skeletal muscles, bones, blood vessels, and organs. There are three main types of facia— superficial fascia, deep fascia, and subserous fascia. These are all present at different depths in the body. Fascia reduces the friction and permits muscles, joints, and organs to easily slide against each other, facilitating movement of the body and preventing tearing...
