Abstract:
Expression of aberrant oligosaccharide moieties of glycoproteins and glycolipids is a typical characteristic of essentially all animal and human tumors, irrespective of the carcinogenic mechanism. Evidence is presented to document that transformation-associated alternations in the oligosaccharide moieties of surface and adhesive glycoproteins are responsible, at least in part, for expression of the malignant phenotype. However, the contribution of carbohydrates to tumor progression and metastasis cannot be fully assessed until more information is available concerning the multiple mechanisms that regulate cell adhesion and carbohydrate biosynthesis. Nevertheless, our rudimentary understanding of the carbohydrate-dependent events involved in cell adhesion and metastasis has resulted in animal studies to develop novel and exciting approaches to cancer therapy.
Insights
Aberrant cell surface carbohydrates, like altered glycoproteins, are hallmarks of cancer. Understanding these changes in tumor cells is key to developing new cancer therapies targeting metastasis.
Area of Science:
- Biochemistry
- Oncology
- Glycobiology
Background:
- Aberrant oligosaccharide expression on glycoproteins and glycolipids is a common feature across all tumor types.
- These changes are linked to the malignant phenotype, influencing cell behavior.
Purpose of the Study:
- To investigate the role of altered cell surface carbohydrates in cancer progression.
- To explore the potential of targeting carbohydrate-dependent mechanisms for cancer therapy.
Main Methods:
- Review of evidence linking transformation-associated alterations in glycoprotein oligosaccharides to the malignant phenotype.
- Discussion of the need for further research into regulatory mechanisms of cell adhesion and carbohydrate biosynthesis.
Main Results:
- Evidence suggests that altered oligosaccharides on surface glycoproteins contribute to the malignant phenotype.
- The precise contribution of carbohydrates to tumor progression and metastasis requires further investigation.
Conclusions:
- Understanding carbohydrate-mediated cell adhesion and biosynthesis is crucial for assessing tumor progression.
- Rudimentary knowledge has already spurred the development of novel animal-based cancer therapies.

Integrins
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,...
Activation of Integrins
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.
