Insights

Transforming growth factor-β (TGF-β) signaling interacts with cell adhesion molecules to influence cell behavior. Aberrant TGF-β activation promotes cancer invasion and metastasis through epithelial-mesenchymal transition (EMT).

Area of Science:

  • Oncology
  • Cell Biology
  • Molecular Biology

Background:

  • Transforming growth factor-β (TGF-β) is crucial for cell differentiation and migration, interacting with the cell adhesion signaling pathway.
  • TGF-β is secreted in an inactive complex and requires release of mature TGF-β for signaling pathway activation.
  • Cell adhesion molecules (CAMs), particularly integrins, play a key role in recognizing and activating latent TGF-β.

Purpose of the Study:

  • To summarize the crosstalk between TGF-β and cell adhesion signaling in cancer.
  • To elucidate the underlying molecular mechanisms of this interaction.

Main Methods:

  • Literature review and synthesis of existing research on TGF-β signaling and cell adhesion in cancer.
  • Analysis of molecular mechanisms involving integrins, CAMs expression, and regulatory molecules like Smad proteins, transcription factors, and non-coding RNAs.

Main Results:

  • TGF-β regulates cell adhesion by modulating CAMs expression.
  • Integrins are essential for the release and activation of mature TGF-β.
  • Aberrant TGF-β pathway activation, driven by dysregulated molecules, promotes tumor invasion and metastasis via epithelial-mesenchymal transition (EMT).

Conclusions:

  • The interplay between TGF-β and cell adhesion signaling is a critical determinant of cancer progression.
  • Understanding these molecular mechanisms provides insights into potential therapeutic targets for inhibiting tumor invasion and metastasis.

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

Intracellular Signaling Affects Focal Adhesions01:17

Intracellular 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.

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cell Adhesion Molecules - Types and Functions

Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

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.
