Introduction:
Soft tissue sarcomas are a group of rare, mesenchymal tumors characterized by dismal prognosis in advanced/metastatic stages. Knowledge of their molecular determinants is still rather limited. However, in recent years, epigenetic regulation - the modification of gene expression/function without DNA sequence variation - has emerged as a key player both in sarcomagenesis and sarcoma progression.
Areas Covered:
Herein, we describe and review the main epigenetic mechanisms involved in chromatin remodeling and their role as disease drivers in different soft tissue sarcoma histotypes, focusing on epithelioid sarcoma, synovial sarcoma, and malignant peripheral nerve sheath tumors. Focusing on chromatin-remodeling complexes, we provide an in-depth on the role of BAF complex alterations in these soft tissue sarcoma histotypes. In parallel, we highlight current state-of-the-art and future perspectives in the development of rational, innovative treatments leveraging on epigenetic dysregulation in soft tissue sarcomas.
Expert Opinion:
Therapeutic options for metastatic/advanced sarcomas are to date very limited and largely represented by cytotoxic agents, with only modest results. In the continuous attempt to find novel targets and innovative, effective drugs, epigenetic mechanisms represent an emerging and promising field of research, especially for malignant peripheral nerve sheath tumors, epithelioid and synovial sarcoma.
Insights
Epigenetic regulation is crucial in soft tissue sarcomas. Targeting epigenetic mechanisms, like BAF complex alterations, offers promising new therapeutic strategies for these rare cancers.
Area of Science:
- Oncology
- Molecular Biology
- Epigenetics
Background:
- Soft tissue sarcomas are rare mesenchymal tumors with poor prognosis in advanced stages.
- Molecular drivers of sarcomagenesis are not fully understood.
- Epigenetic regulation is increasingly recognized as a key factor in sarcoma development and progression.
Purpose of the Study:
- To review epigenetic mechanisms in soft tissue sarcomas.
- To focus on chromatin remodeling complexes, particularly the BAF complex, in specific sarcoma histotypes.
- To discuss current and future therapeutic strategies targeting epigenetic dysregulation.
Main Methods:
- Review of literature on epigenetic mechanisms in soft tissue sarcomas.
- Focus on epithelioid sarcoma, synovial sarcoma, and malignant peripheral nerve sheath tumors.
- Analysis of the role of BAF complex alterations in these histotypes.
Main Results:
- Epigenetic mechanisms, including chromatin remodeling, are significant drivers in soft tissue sarcomas.
- Alterations in the BAF complex are implicated in specific sarcoma histotypes.
- Epigenetic dysregulation presents a promising avenue for novel therapeutic development.
Conclusions:
- Epigenetic dysregulation is a critical aspect of soft tissue sarcoma biology.
- Targeting epigenetic mechanisms, especially BAF complex alterations, holds potential for innovative treatments.
- Further research into epigenetic therapies could improve outcomes for patients with advanced/metastatic sarcomas.
