Mutational events in mouse myeloma cells.

S L Morrison, M D Scharff

    Critical Reviews in Immunology
    |September 1, 1981
    PubMed
    Summary

    Mouse myeloma cells exhibit frequent variations in immunoglobulin expression and structure. This review examines variant phenotypes and discusses potential mechanisms driving immunoglobulin gene instability.

    Area of Science:

    • Immunology
    • Molecular Biology
    • Genetics

    Background:

    • Cultured mouse myeloma cells are a model system for studying immunoglobulin gene regulation.
    • These cells are known to undergo spontaneous genetic alterations affecting immunoglobulin production.

    Purpose of the Study:

    • To review identified variants in immunoglobulin expression and structure from cultured mouse myeloma cells.
    • To discuss the underlying mechanisms contributing to somatic instability of immunoglobulin genes.

    Main Methods:

    • Literature review of studies on mouse myeloma cell variants.
    • Analysis of reported phenotypes of immunoglobulin variants.
    • Discussion of proposed genetic and epigenetic mechanisms.

    Main Results:

    • Cataloging of diverse variant phenotypes affecting immunoglobulin expression levels and protein structure.
    • Identification of potential mechanisms including gene rearrangements, mutations, and regulatory element alterations.
    • Highlighting the dynamic nature of immunoglobulin gene expression in myeloma cells.

    Conclusions:

    • Mouse myeloma cell variants provide insights into immunoglobulin gene regulation and somatic hypermutation.
    • Understanding these mechanisms is crucial for research in B-cell development and myeloma pathogenesis.
    • Further research is needed to fully elucidate the complex pathways of immunoglobulin gene instability.
