Oncogenes: implications for the diagnosis and treatment of cancer

Insights

Cellular oncogenes are vital genes involved in normal cell growth. Aberrations in these genes, known as oncogenes, can lead to cancer development and offer targets for new detection and treatment strategies.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cancer Research

Background:

  • Cellular oncogenes are a conserved gene family in vertebrates.
  • These genes encode proteins with critical roles in cell proliferation and differentiation.
  • Dysregulation of cellular oncogenes can contribute to malignant transformation.

Purpose of the Study:

  • To review the fundamental biology of cellular oncogenes.
  • To explore the mechanisms by which oncogenes contribute to carcinogenesis.
  • To discuss the implications of oncogene research for cancer detection and treatment.

Main Methods:

  • Literature review of studies on cellular oncogenes.
  • Analysis of gene structure, viral integration, and chromosomal translocation.
  • Examination of altered oncogene product formation.

Main Results:

  • Cellular oncogenes possess diverse protein functions, including DNA binding and kinase activity.
  • Mechanisms of oncogene activation in cancer include viral incorporation, mutation, and translocation.
  • Altered oncogene products are frequently observed in malignant cells.

Conclusions:

  • Understanding oncogene biology is crucial for advancing cancer diagnostics.
  • Targeting oncogenes may provide novel therapeutic strategies for cancer treatment.

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

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.

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
