Area of Science:

  • Oncology
  • Genetics
  • Systems Biology

Background:

  • Ewing sarcoma (EwS) is a highly aggressive pediatric bone cancer.
  • It is characterized by the EWSR1-FLI1 gene fusion, producing a chimeric transcription factor.
  • Despite a well-identified driver, EwS is genetically stable, offering a unique model for systems biology.

Purpose of the Study:

  • To explore the complex mechanisms of EWSR1-FLI1 oncogene action in EwS.
  • To provide an overview of EwS molecular profiling resources and datasets.
  • To highlight systems biology studies and their role in understanding EwS.

Main Methods:

  • Reviewing existing molecular profiling resources for EwS tumors and cell lines.
  • Compiling a catalogue of publicly available omics and other datasets.
  • Highlighting systems biology studies, including mathematical modeling and data integration.

Main Results:

  • EWSR1-FLI1 has complex, systemic effects on cellular processes.
  • Multiple molecular mechanisms, including transcriptional and epigenetic regulation, are involved.
  • A comprehensive catalogue of EwS data resources is presented.

Conclusions:

  • Understanding EwS requires a systems-wide approach due to its complexity.
  • Further research is needed to connect the driver mutation to cellular phenotypes.
  • This chapter serves as a guide for systems biology research in EwS.
