Summary
Ewing's tumour, a bone cancer, often involves a specific gene fusion (EWS-ETS) that drives cancer development. Research suggests these tumours originate from mesenchymal stem cells.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Ewing's tumour is the second most common primary bone cancer.
- It is characterized by a recurrent t(11;22) translocation in 85% of cases, creating the EWS-FLI-1 fusion gene.
Discussion:
- The EWS-ETS fusion gene is causative in Ewing's tumour development.
- Its mechanism involves aberrant regulation of genes controlling cell cycle, signal transduction, and migration.
- The cellular origin of Ewing's tumour has been debated, with recent evidence pointing to mesenchymal stem cells.
Key Insights:
- The EWS-FLI-1 fusion gene plays a critical role in Ewing's tumour pathogenesis.
- Abnormal transcription regulation by EWS-ETS impacts key cellular processes.
- Mesenchymal stem cells are implicated as the cell of origin.
Outlook:
- Further research into EWS-ETS targets may reveal new therapeutic strategies.
- Understanding the mesenchymal stem cell origin could inform targeted therapies.
- Investigating the precise mechanisms of oncogenesis can lead to improved Ewing's tumour treatment.

Cancer-Critical Genes II: Tumor Suppressor Genes
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.

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...

Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
