Insights

A new hypothesis suggests that multiple oncogene pathways, not single genes, drive cancer. Activating all genes in a specific pathway, influenced by carcinogen and tissue type, leads to tumor formation.

Area of Science:

  • Oncology
  • Molecular Biology
  • Carcinogenesis

Background:

  • Cellular oncogene activation shows carcinogen and tissue specificity in animal tumor models.
  • No single oncogene activation is sufficient or necessary for tumorigenesis.
  • Existing models do not fully explain experimental observations in tumorigenesis.

Purpose of the Study:

  • To propose a novel hypothesis for experimental tumorigenesis.
  • To explain the role of multiple oncogene pathways in cancer development.
  • To provide a framework for understanding carcinogen and tissue-specific oncogene activation.

Main Methods:

  • Developed a hypothesis based on multiple, tissue-specific oncogene pathways.
  • Modeled spontaneous and carcinogen-specific oncogene activation probabilities.
  • Assumed activation of all oncogenes within a pathway leads to transformation.

Main Results:

  • The model predicts relative carcinogen potency.
  • Calculates the percentage of tumors with specific activated oncogenes.
  • Explains dose-response relationships in carcinogen-induced tumors.

Conclusions:

  • The proposed hypothesis is consistent with experimental observations of oncogene activation.
  • Multiple oncogene pathways offer a more comprehensive explanation for tumorigenesis.
  • This model aids in understanding the complex mechanisms of cancer induction.

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-oncogenes01:33

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...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Mutagenicity and Carcinogenicity01:25

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...
