    Area of Science:

    • Oncology
    • Glycobiology
    • Immunology

    Background:

    • Surface carbohydrate structures on cells undergo alterations during neoplasia.
    • These changes are observed across various comparisons, including normal vs. tumor tissues and different metastatic cell variants.

    Purpose of the Study:

    • To review alterations in surface carbohydrate structures associated with neoplasia.
    • To explore the role of these altered glycoconjugates in tumor growth, immune recognition, and as tumor-associated antigens.

    Main Methods:

    • Comparative analysis of normal tissues, tumors, and cultured cells.
    • Review of studies on nucleotide sugar biosynthesis and glycosyltransferase changes.
    • Examination of monoclonal antibody recognition of tumor-associated antigens.

    Main Results:

    • Consistent alterations in surface glycolipids, glycoproteins, and glycosaminoglycans are found in neoplastic cells.
    • Altered glycoconjugates can be linked to cell growth control and may act as receptors for growth factors.
    • Monoclonal antibodies targeting tumor-associated antigens frequently detect altered carbohydrate structures.

    Conclusions:

    • Altered cell surface glycoconjugates are a hallmark of neoplasia.
    • These changes play a role in tumor growth regulation and immune system recognition.
    • Further investigation into glycosylation alterations, growth control, and tumor immunity is warranted.
