    Insights

    Virus binding to cell receptors triggers gene responses. Different viruses like poliovirus and HSV-I induce distinct immediate-early gene responses, affecting protooncogene expression in human cells.

    Area of Science:

    • Virology
    • Molecular Biology
    • Cellular Biology

    Background:

    • Virus-receptor binding initiates cellular signaling pathways.
    • Cellular responses to viral infection involve the regulation of gene expression.
    • Immediate-early genes play crucial roles in the cellular response to stimuli.

    Purpose of the Study:

    • To investigate the differential gene responses induced by distinct viral ligands.
    • To analyze the impact of poliovirus and HSV-I binding on human diploid cells.
    • To determine if viral binding affects the expression of protooncogenes.

    Main Methods:

    • Utilizing human diploid cells as a model system.
    • Infecting cells with specific viruses (poliovirus and HSV-I).
    • Analyzing the resulting cellular primary gene responses, focusing on immediate-early genes and protooncogenes.

    Main Results:

    • Different viruses induced distinct patterns of immediate-early gene expression.
    • The binding of poliovirus and HSV-I resulted in unique gene response profiles.
    • Early expression of protooncogenes was observed to be either enhanced or suppressed.

    Conclusions:

    • Virus-specific binding to cellular receptors elicits differential gene expression programs.
    • The interaction of viruses like poliovirus and HSV-I with human cells modulates protooncogene expression.
    • Understanding these differential responses is key to comprehending viral pathogenesis and cellular defense mechanisms.

    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...

    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.

    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...
