Methylation-regulated miR-374a-5p and miR-374b-5p Suppress Glycolysis and Malignant Progression of Head and Neck Squamous Cell Carcinoma by Targeting DEPDC1
To investigate the role of miR-374a-5p and miR-374b-5p in regulating glycolysis and tumor progression in head and neck squamous cell carcinoma (HNSCC).
Key Findings:
miR-374a-5p and miR-374b-5p levels were significantly downregulated in HNSCC tissues compared to normal controls.
Overexpression of miR-374a-5p and miR-374b-5p inhibited proliferation, migration, invasion, and tumor growth in vivo.
miR-374a-5p and miR-374b-5p bind to the 3′UTR of DEPDC1, suppressing its expression.
DEPDC1 promotes proliferation, migration, invasion, and glycolysis in HNSCC cells.
Promoter methylation is a key mechanism suppressing miR-374a-5p and miR-374b-5p expression in HNSCC.
Interpretation:
The study highlights the regulatory role of miR-374a-5p and miR-374b-5p in glycolysis and tumor advancement in HNSCC, suggesting potential therapeutic targets.
Limitations:
The study primarily relies on in vitro and in vivo models, which may not fully replicate human disease.
Further clinical validation is needed to confirm the findings.
Conclusion:
The findings provide novel insights into the role of miR-374a-5p and miR-374b-5p in HNSCC, emphasizing their potential as molecular targets for treatment through modulation of glycolytic metabolism.
