Oncogenes and Oncogene Impact Factor: A Comprehensive Exploration


Cancer, a complex and multifaceted disease, has been the subject of extensive research for decades. One of the pivotal areas of study in the field of oncology is the understanding of oncogenes and their impact factors. Oncogenes, genes with the potential to cause cancer when altered or overexpressed, are at the core of cancer development and progression.

Oncogenes are genes that, under normal circumstances, play essential roles in regulating cell growth, division, and apoptosis. However, when these genes undergo specific mutations or experience abnormal expression levels, they can become oncogenes, promoting uncontrolled cell growth and tumor formation. The transformation of proto-oncogenes into oncogenes is a critical step in the development of cancer.

The impact factor of cancer-related genes refers to its influence on the initiation, growth, and spread of cancer. It encompasses various factors such as mutation, gene amplification, chromosomal rearrangements, and altered expression levels. The impact factor determines the ability to drive tumor development and its potential as a therapeutic target.

Research Status and Findings:

The study has seen remarkable progress, with numerous research articles published in esteemed journals like Nature, Science, and The Journal of Clinical Oncology. The National Cancer Institute (NCI) and the AACR have been instrumental in funding and promoting research in this field. Key findings have led to the identification of various oncogenes and their impact factors, paving the way for targeted therapies and improved patient outcomes.

The Discovery Process:

The discovery began with the identification of viral oncogenes, which were capable of transforming normal cells into cancerous ones. Subsequent research led to the identification of cellular oncogenes, such as the src gene, which marked a significant milestone in the understanding of cancer genetics. The advent of molecular biology techniques, including DNA sequencing and gene expression profiling, has accelerated the discovery process, enabling researchers to pinpoint numerous oncogenes across different cancer types.


1.Growth Factor Receptors:

  • EGFR (Epidermal Growth Factor Receptor): Overexpression or activating mutations in EGFR are common in various cancers, including lung and breast cancer.
  • HER2 (Human Epidermal Growth Factor Receptor 2) : Amplification or overexpression of HER2 is associated with aggressive breast and gastric cancers.

2.Signal Transducers:

  • KRAS: Mutations in the KRAS gene are prevalent in colorectal and lung cancers, leading to constitutive activation of signaling pathways that promote tumor growth.
  • BRAF: The BRAF gene is commonly mutated in melanoma and other cancers, resulting in the activation of the MAPK signaling pathway.

3.Cell Cycle Regulators:

  • CDK4: Overexpression or amplification of CDK4 can lead to uncontrolled cell cycle progression, contributing to the development of various cancers.
  • MYC: The MYC gene is often amplified or overexpressed in multiple cancer types and plays a role in cell proliferation, apoptosis, and metabolism.

Oncogene Impact Factor:

  1. Mutation: Point mutations, insertions, or deletions can alter the function of an oncogene, leading to its constitutive activation.
  2. Amplification: Increased copy numbers of an oncogene can result in higher protein levels, promoting tumor growth.
  3. Fusion: Gene fusions, such as the BCR-ABL fusion gene in chronic myeloid leukemia, can create novel oncogenic proteins with enhanced transforming abilities.

US Testing Companies and Pricing:

In the United States, several companies offer oncogene testing, utilizing next-generation sequencing and other advanced techniques. These companies include:

  1. Foundation Medicine: Offers comprehensive genomic profiling, including testing for various cancer-related genes. Pricing ranges from 580-3,200, depending on the test.
  2. Guardant Health: Provides liquid biopsies for the detection of cancer-related genes. Pricing starts around $2,500.
  3. Myriad Genetics: Specializes in hereditary cancer testing, including BRCA1/2 mutations. Pricing varies based on the specific test.

Cancer Prevention and Treatment:

The knowledge gained from studying oncogene impact factor has revolutionized cancer prevention and treatment strategies. Targeted therapies, designed to inhibit the activity of specific cancer-related genes, have shown promising results in the treatment of various cancers. For example:

  • EGFR inhibitors, such as gefitinib and erlotinib, are effective in treating non-small cell lung cancer with EGFR mutations.
  • HER2-targeted therapies, like trastuzumab, have improved outcomes for patients with HER2-positive breast cancer.


Oncogenes and their impact factors play a pivotal role in the development and progression of cancer. Advances in research have led to the identification of various oncogenes and their impact factors, providing valuable insights for targeted therapies and personalized medicine. The availability of oncogene testing in the US has facilitated the customization of cancer treatment plans, ultimately improving patient outcomes. Continued research in this field will further enhance our understanding of cancer biology and contribute to more effective prevention and treatment strategies.
