Summary
Selectins (E-selectin, P-selectin, L-selectin) and their ligands mediate cancer cell adhesion to blood vessels, promoting metastasis. Targeting selectins offers a novel therapeutic strategy for controlling cancer spread.
Area of Science:
- Cellular and Molecular Biology
- Oncology
- Immunology
Background:
- Selectins (E-selectin, P-selectin, L-selectin) are adhesion molecules vital for leukocyte trafficking during inflammation.
- Emerging evidence implicates selectins in the adhesion of circulating cancer cells to the vasculature.
Purpose of the Study:
- To review the roles of E-selectin and P-selectin in cancer progression and metastasis.
- To highlight the significance of selectin-ligand interactions in cancer metastasis.
Main Methods:
- Literature review focusing on selectin function in cancer metastasis.
- Analysis of studies investigating selectin ligands, such as Sialyl Lewis X (sLe(x)) and Sialyl Lewis A (sLe(a)).
Main Results:
- Selectins mediate the adhesion of cancer cells to blood vessel walls, facilitating distant organ metastasis.
- High expression of selectin ligands (sLe(x), sLe(a)) on various carcinomas correlates with poor prognosis.
- Selectin-ligand interactions are involved in cancer cell signal transduction and cellular functions.
Conclusions:
- Selectins and their ligands play a critical role in cancer metastasis.
- Understanding these interactions supports the development of novel selectin-targeted therapies to inhibit cancer spread.

01:25Selectins
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...
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...

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.

01:15Activation 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.

02:38Mitogens and the Cell Cycle
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

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,...
