    Insights

    Cancer development involves oncogenes, which are normal cellular genes that become active during neoplastic transformation. These activated oncogenes may be the common pathway for various cancer-causing agents.

    Area of Science:

    • Molecular Biology
    • Cancer Genetics
    • Oncology

    Background:

    • Cancer causation involves multiple factors, but the mechanisms of neoplastic transformation are not fully understood.
    • Normal mammalian cells possess gene sequences homologous to viral oncogenes.
    • These cellular oncogenes are typically inactive or expressed at low levels in healthy cells.

    Purpose of the Study:

    • To explore the role of oncogenes in mediating neoplastic transformation.
    • To elucidate the connection between cellular oncogenes and cancer development.

    Main Methods:

    • Review of recent developments in molecular biology of tumor viruses.
    • Analysis of cancer genetics research.
    • Comparison of gene sequences in normal cells and oncogenic viruses.

    Main Results:

    • Identification of cellular oncogenes homologous to viral oncogenes.
    • Demonstration that oncogenes are activated in neoplastic cells.
    • Observation of increased production of specific gene products linked to transformation.

    Conclusions:

    • Activated oncogenes may represent a common pathway for cancer initiation by chemicals, radiation, and viruses.
    • Understanding oncogene activation is crucial for comprehending cancer development.

    Cancers Originate from Somatic Mutations in a Single Cell

    Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

    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.
    Such genes that act...
    Cancer Prevention02:59

    Cancer Prevention

    Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

    Mutagenicity and Carcinogenicity

    Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...
