    Insights

    Oncogenic viruses cause persistent infections leading to uncontrolled cell growth. They use diverse mechanisms, including gene integration and oncogenic protein production, to transform cells and initiate cancer.

    Area of Science:

    • Virology
    • Molecular Biology
    • Oncology

    Context:

    • Oncogenic viruses are pathogens that can induce cancer.
    • Understanding viral oncogenesis is crucial for developing antiviral therapies and cancer treatments.

    Purpose:

    • To elucidate the diverse mechanisms by which oncogenic viruses induce cell transformation and contribute to oncogenesis.
    • To differentiate the strategies employed by oncogenic DNA viruses and RNA viruses in cellular transformation.

    Summary:

    • Oncogenic viruses establish persistent infections, driving uncontrolled cell proliferation through cell transformation.
    • DNA viruses often integrate viral genes into the host genome, inactivating tumor suppressor proteins like p53.
    • RNA viruses employ various strategies, including encoding oncogenic proteins, integrating viral enhancers near growth genes, or expressing regulatory proteins like tax, to promote rapid tumor formation.

    Impact:

    • Provides a comprehensive overview of viral oncogenesis mechanisms.
    • Highlights the distinct pathways utilized by DNA and RNA oncogenic viruses.
    • Establishes virus-induced cell transformation as a critical initial step in cancer development.

    Mechanisms of Retrovirus-induced Cancers

    Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

    Rous Sarcoma Virus (RSV) and Cancer

    Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
    RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

    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.
