Summary
Fusion oncogenes are key cancer biomarkers, acting as mutations and therapeutic targets. New research reveals these fusion genes also occur in normal tissues, challenging our understanding of gene definition and function.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Chromosomal translocations and fusion oncogenes are specific biomarkers for malignancies.
- They encode both the cause of the cancer and a potential treatment target.
- Previously, fusion oncogenes were considered rare in solid tumors.
Purpose of the Study:
- To expand the understanding of fusion oncogenes in solid epithelial tumors.
- To investigate the presence and implications of chimeric transcripts in normal tissues.
- To redefine the role of gene fusion in cancer and normal physiology.
Main Methods:
- Utilizing advanced molecular methodologies beyond macroscopic cytogenetics.
- Analyzing large datasets of annotated clinical and normal tissue samples.
- Characterizing the chimeric transcriptome in both healthy and diseased states.
Main Results:
- Discovery of a growing number of recurrent fusion oncogenes in common and rare solid tumors.
- Identification of numerous tandem or chimeric transcripts in normal tissues.
- Observation of a known fusion oncogene template within normal tissue.
Conclusions:
- Fusion oncogenes are more prevalent in solid tumors than previously thought.
- Chimeric transcripts are common in normal tissues, suggesting a need to redefine gene structure.
- Understanding the chimeric transcriptome is crucial for cancer diagnosis, prognosis, and therapy.

02:21Cancers 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...

01:33Cancer-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.
