Summary
Cell surface glycans and their binding partners are crucial for cancer metastasis. Understanding these interactions can reveal new therapeutic targets for preventing tumor spread.
Area of Science:
- Oncology
- Cell Biology
- Biochemistry
Background:
- Metastasis, the spread of cancer, involves sequential, ordered events.
- Cell surface glycans and their interactions with lectins are critical for these adhesive processes.
- Aberrant glycosylation is a hallmark of cancer, influencing tumor cell dissemination.
Purpose of the Study:
- To review the role of cell surface glycans and their binding partners in cancer metastasis.
- To highlight specific glycan-lectin interactions in different stages of metastasis.
Main Methods:
- Literature review focusing on cell surface glycans and lectins in cancer metastasis.
- Analysis of glycan involvement in tumor cell adhesion, invasion, migration, angiogenesis, and immune evasion.
Main Results:
- Glycans mediate crucial adhesive interactions, including E-cadherin and siglec-mediated disaggregation.
- Integrins, laminin, and CD44 are involved in tumor cell invasion and migration.
- Heparan sulfate and C-/S-type lectins play roles in tumor angiogenesis and vasculature interactions.
Conclusions:
- Cell surface glycans and endogenous lectins are key regulators of cancer metastasis.
- Targeting these glycan-lectin interactions may offer novel strategies for cancer treatment and prevention.

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...

01:14Glycocalyx and its Functions
The glycocalyx is a carbohydrate-rich, fuzzy-appearing layer on the outer surface of the cell membrane. It is highly hydrophilic, because of this it attracts large amounts of water to the cell's surface. This aids the cell's interaction with the watery environment and also helps it to obtain substances dissolved in the water. It is also important for cell identification, self/non-self determination, and embryonic development and is used in cell-to-cell attachments to form tissues.

01:20Cell 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).

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...
01:31Immunoglobulin-like Cell Adhesion Molecules
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...
