Insights

Tumour oncogenes reprogram epigenomes, initiating cancer through stem cell changes, not just proliferation. This reveals a new role for oncogenes in cancer origin and suggests novel therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Epigenetics

Background:

  • Tumour-associated oncogenes typically induce uncontrolled cell proliferation and genomic instability.
  • Current cancer therapies targeting oncogenes assume they are essential for all tumour cell proliferation.

Purpose of the Study:

  • To analyze recent evidence on oncogene function in cancer development.
  • To propose an updated model of oncogene function incorporating epigenetic reprogramming.
  • To explore new anti-cancer intervention strategies based on this updated model.

Main Methods:

  • Review and analysis of existing scientific literature on oncogenes, epigenetics, and cancer development.
  • Comparative analysis of current and proposed models of oncogene function.

Main Results:

  • Oncogenes are not essential for proliferation in all tumour cell types.
  • Oncogenes contribute to cancer by reprogramming the epigenome, initiating tumorigenesis via stem cell reprogramming.
  • This uncovers a novel role for oncogenes in the origin of cancer.

Conclusions:

  • An updated model of oncogene function explains diverse genotype-phenotype associations in human cancer.
  • Oncogene-induced stem cell reprogramming is a key mechanism in tumorigenesis.
  • This revised understanding opens new avenues for developing innovative anti-cancer therapies.

Infants are born with amazing cognitive resources at their disposal, but they don’t know how to use them effectively. In order to harness the power of their brains, humans must develop high-level cognitive processes that manage basic brain functions. These processes make up what psychologists refer to as executive function. Executive function is a key factor in many self-regulatory behaviors,...

Mapping the Structure-Function Relationships of Disordered Oncogenic Transcription Factors Using Transcriptomic Analysis

Intrinsically disordered domains are important for oncogenic fusion transcription factor function. To therapeutically target these proteins, a more detailed understanding of the regulatory mechanisms employed by these domains is required. Here, we use transcriptomics to map important structural features of the intrinsically disordered EWS domain in Ewing...

Studying Pancreatic Cancer Stem Cell Characteristics for Developing New Treatment Strategies

Pancreatic cancer stem cells (CSCs) can be expanded in vitro using the anchorage-independent sphere culture technique, which represents a powerful tool to study CSC biology and can serve as the first step to develop novel CSC-targeting therapies. Here the methodology for expanding, analyzing and targeting of pancreatic CSCs is...

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...

Fruit Development, Structure, and Function01:58

Fruit Development, Structure, and Function

Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.
