Summary
Tetraspanins, proteins involved in cell adhesion, form complexes with integrins to regulate cancer cell migration. Understanding these interactions is key to targeting distant metastasis, a major cause of cancer mortality.
Area of Science:
- Molecular biology
- Cell biology
- Oncology
Context:
- Distant metastasis is the primary cause of cancer-related deaths.
- Tetraspanins (transmembrane 4 superfamily, TM4SF) are crucial cell surface proteins.
- Integrins are key mediators of cell adhesion and migration.
Purpose:
- To review the structure and function of tetraspanins.
- To elucidate the role of tetraspanins in regulating cancer metastasis.
- To highlight the formation of tetraspanin-integrin complexes in metastasis.
Summary:
- Tetraspanins form multimolecular complexes with integrins on the cell surface.
- These complexes regulate critical cellular processes including adhesion and migration.
- The review details how tetraspanin-integrin interactions influence tumor metastasis.
Impact:
- Provides insights into the molecular mechanisms of cancer metastasis.
- Identifies tetraspanin-integrin complexes as potential therapeutic targets.
- Contributes to understanding how to inhibit cancer spread and improve patient outcomes.

02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

02:17The 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...
01:15Activation of Integrins
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.

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.

01:10Integrins
Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...

01:35Cancer Cell Migration through Invadopodia
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, invadopodia can...
