    Insights

    The discovery of oncogenes began in 1969, revealing viral src genes and their cellular counterparts (c-onc). These cellular oncogenes are crucial in cancer development and human cancer gene studies.

    Area of Science:

    • Oncology
    • Virology
    • Molecular Biology

    Context:

    • The identification of the first oncogene, src, in avian sarcoma virus B77 in 1969 marked a significant breakthrough.
    • Subsequent research identified numerous oncogenes in various sarcoma and acute leukosis viruses.

    Purpose:

    • To explore the origins and characteristics of viral oncogenes.
    • To investigate the role of cellular oncogenes (c-onc) in viral oncogene formation.
    • To discuss the significance of c-onc activation in carcinogenesis and human cancer research.

    Summary:

    • Viral oncogenes, originating from cellular counterparts (c-onc), were first identified in avian sarcoma virus B77.
    • Some c-oncs were proven to be oncogenic when integrated into retroviral genomes or coupled with viral LTRs.
    • The study emphasizes the critical role of c-onc activation in general carcinogenesis, linking to human cancer gene discoveries.

    Impact:

    • This research provides foundational knowledge on oncogenes and their cellular origins.
    • It highlights the link between viral and cellular oncogenes in cancer development.
    • The findings contribute to understanding the molecular basis of human carcinogenesis and cancer gene research.

    Cancer-Critical Genes I: Proto-oncogenes

    Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
    When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

    Mouse Models of Cancer Study

    Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
    The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
