MicroRNAs and Potential Targets in Osteosarcoma: Review.

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Osteosarcoma is the most common bone cancer in children and young adults.
• Current treatments like surgery and chemotherapy have limitations, necessitating novel therapeutic approaches.
• MicroRNAs (miRNAs) are crucial regulators of cellular processes and are implicated in osteosarcoma pathogenesis.

Purpose of the Study:

• To review the current understanding of miRNA roles in osteosarcoma.
• To evaluate the potential of miRNAs as diagnostic biomarkers and therapeutic agents for osteosarcoma.
• To summarize preclinical findings on miRNA-targeted therapies in osteosarcoma.

Main Methods:

• Literature review of studies on miRNAs in osteosarcoma.
• Analysis of miRNA involvement in cell-cycle control, proliferation, metabolism, and apoptosis.
• Summary of preclinical efficacy of inhibiting oncogenic miRNAs or expressing tumor suppressor miRNAs.

Main Results:

• miRNAs function as oncogenes or tumor suppressors in osteosarcoma.
• Targeting specific miRNAs shows potential for therapeutic intervention.
• miR-34a has advanced to clinical trials for other cancers, indicating miRNA therapeutic feasibility.

Conclusions:

• miRNAs represent promising biomarkers for osteosarcoma diagnosis.
• Targeting miRNAs offers a novel therapeutic avenue for osteosarcoma.
• A comprehensive understanding of osteosarcoma pathogenesis is crucial for identifying effective miRNA-based treatments.
