The Role of Ewing’s Sarcoma Chromosomal Translocation
Chromosomal translocation plays a crucial role in the development and progression of Ewing’s sarcoma, a rare type of cancer primarily affecting children and young adults. This genetic abnormality occurs when there is an exchange of genetic material between two different chromosomes.
Ewing’s sarcoma is characterized by a specific translocation involving two genes: EWSR1 (Ewing Sarcoma breakpoint region 1) and an ETS transcription factor gene, most commonly FLI1 (Friend Leukemia Integration 1). This translocation results in the fusion of EWSR1 and FLI1, creating a chimeric gene known as EWSR1-FLI1.
Mechanism and Consequences of Chromosomal Translocation
The EWSR1-FLI1 fusion gene acts as an oncogene, meaning it has the potential to cause uncontrolled cell growth and tumor formation. This abnormal gene produces a hybrid protein that disrupts normal cellular processes, leading to the formation of Ewing’s sarcoma.
The EWSR1-FLI1 protein alters the expression of various genes involved in cell growth, differentiation, and apoptosis (programmed cell death). It interferes with the normal regulation of these genes, promoting the survival and proliferation of cancer cells.
Effects on Tumor Cells
The EWSR1-FLI1 fusion gene and its protein product have been found to play a crucial role in the initiation and maintenance of Ewing’s sarcoma. They contribute to the malignant transformation of normal cells into cancer cells and sustain the growth and survival of tumor cells.
Additionally, research has shown that the EWSR1-FLI1 protein interacts with various cellular pathways involved in cancer progression, such as DNA repair mechanisms, cell cycle control, and angiogenesis (the formation of new blood vessels to support tumor growth).
