Small Non-Coding RNAs in Soft-Tissue Sarcomas: State of the Art and Future Directions

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Soft-tissue sarcomas (STS) are rare, diverse tumors originating from connective tissues, with liposarcoma (LPS) being a common subtype.
• STS subtypes exhibit distinct biological characteristics influencing treatment response and patient outcomes.
• Small non-coding RNAs (sncRNAs) are key regulators of gene expression, with microRNAs (miRNAs) and tRNA-derived ncRNAs playing significant roles in tumor biology.

Approach:

• This review synthesizes current knowledge on sncRNAs in STS, focusing on LPS.
• It examines the involvement of sncRNAs in STS tumorigenesis and differentiation processes.
• The review highlights the potential of sncRNAs as diagnostic biomarkers and therapeutic targets for STS.

Key Points:

• sncRNAs, including miRNAs and tRNA-derived ncRNAs, are implicated in the development and progression of STS.
• Understanding sncRNA roles is crucial for developing targeted therapies and biomarkers.
• Despite progress, clinical translation of sncRNA-based strategies for STS remains challenging.

Conclusions:

• sncRNAs represent a promising area for novel therapeutic and diagnostic strategies in STS, especially LPS.
• Further investigation into tRNA-derived ncRNAs in STS is warranted.
• Bridging the gap between research findings and clinical application is essential for advancing STS treatment.
