Summary
This study identifies key genes involved in Ewing sarcoma (ES), a childhood bone cancer. Findings highlight CDCA8, MAD2L1, and FANCI as potential targets for improving ES diagnosis and treatment.
Area of Science:
- Oncology
- Molecular Biology
- Genomics
Background:
- Ewing sarcoma (ES) is a prevalent pediatric bone cancer with poorly understood molecular mechanisms.
- Ethnic variations influence ES incidence and treatment outcomes, necessitating further research into its causes.
Purpose of the Study:
- To identify differentially expressed genes (DEGs) in ES.
- To elucidate the molecular mechanisms underlying ES.
- To discover potential diagnostic and therapeutic targets for ES.
Main Methods:
- Downloaded and analyzed three Gene Expression Omnibus (GEO) microarray datasets (GSE68776, GSE45544, GSE17674).
- Screened for DEGs and performed enrichment analysis.
- Constructed a protein-protein interaction (PPI) network using STRING and Cytoscape.
- Conducted survival and immune infiltration analyses.
Main Results:
- Identified 629 DEGs (206 up-regulated, 423 down-regulated).
- Enrichment analysis revealed involvement in pathways like cell cycle, p53, and cancer pathways.
- Screened 10 hub genes, with CDCA8, MAD2L1, and FANCI showing potential prognostic significance.
Conclusions:
- CDCA8, MAD2L1, and FANCI are implicated in the occurrence and prognosis of ES.
- This research provides insights into ES molecular mechanisms.
- Identified DEGs and key genes offer potential targets for ES diagnosis and treatment.
