Summary
Ewing sarcoma, a rare and aggressive cancer, arises from mesenchymal progenitor cells. Recent discoveries shed light on the EWS-FLI-1 fusion protein
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Sarcomas are rare malignancies originating from mesenchymal progenitor cells, often aggressive and resistant to conventional therapies.
- Ewing sarcoma family of tumors (ESFT) is a significant bone and soft tissue cancer in children and young adults.
- ESFT is characterized by the EWS-FLI-1 fusion gene, resulting from a specific chromosomal translocation.
Purpose of the Study:
- To review recent advancements in understanding Ewing sarcoma biology.
- To explore the origins of ESFT and the role of the EWS-FLI-1 fusion protein.
- To elucidate mechanisms of EWS-FLI-1-induced transformation and identify cell origins.
Main Methods:
- Review of current scientific literature on Ewing sarcoma.
- Analysis of genetic and molecular mechanisms underlying ESFT development.
- Identification of potential mesenchymal progenitor cell origins for ESFT.
Main Results:
- The EWS-FLI-1 fusion protein acts as an aberrant transcriptional activator.
- Altered gene expression by EWS-FLI-1 contributes to ESFT pathogenesis.
- Ongoing research aims to pinpoint the precise cellular origins of ESFT.
Conclusions:
- Further research is crucial to fully understand EWS-FLI-1-mediated transformation.
- Identifying the primary cells of origin is key to developing targeted therapies.
- Recent discoveries offer new insights into Ewing sarcoma biology and origins.

02:30Metastasis
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...

01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
02:17The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
