Background:
MicroRNAs (miRNAs) play crucial roles in head and neck squamous cell carcinoma (HNSCC). This study investigates whether miR-31, miR-96, and miR-182 are involved in targeting Numb during HNSCC.
Methods:
The expression of miR-31/96/182 in tumor tissues was analyzed. Reporter assay, knockdown, expression, and oncogenic analysis were carried out in cell lines.
Results:
Upregulation of miR-31/96/182 was detected in tumor tissues. In addition, advanced tumors showed higher expression levels of these miRNAs. The expression of these miRNAs was upregulated after treatment with areca ingredients (P < .01 or P < .001). These miRNAs directly targeted the 3' untranslated region (UTR) sequence of the Numb gene. An increased migration and invasion of HNSCC cells was associated with the exogenous expression of miR-31/96/182 (P < .01 or P < .001), and this was reverted by expression of Numb.
Conclusion:
This study provides new evidence demonstrating that there is frequent and concordant upregulation of miR-31, miR-96, and miR-182 during HNSCC and these miRNAs co-target Numb.

MicroRNAs miR-31, miR-96, and miR-182 are upregulated in head and neck squamous cell carcinoma (HNSCC). These miRNAs co-target Numb, influencing cancer cell migration and invasion.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- MicroRNAs (miRNAs) are critical regulators in head and neck squamous cell carcinoma (HNSCC).
- The specific roles of miR-31, miR-96, and miR-182 in HNSCC pathogenesis require elucidation.
- Investigating the targeting of Numb by these miRNAs is essential for understanding HNSCC progression.
Purpose of the Study:
- To determine the expression levels of miR-31, miR-96, and miR-182 in HNSCC tissues.
- To investigate the direct targeting of the Numb gene by miR-31, miR-96, and miR-182.
- To analyze the functional impact of these miRNAs on HNSCC cell behavior.
Main Methods:
- Analysis of miR-31, miR-96, and miR-182 expression in HNSCC tumor tissues.
- Utilizing reporter assays and knockdown experiments in HNSCC cell lines.
- Performing oncogenic and expression analyses to assess miRNA function.
Main Results:
- Concordant upregulation of miR-31, miR-96, and miR-182 was observed in HNSCC tumor tissues, correlating with advanced tumor stages.
- These miRNAs were found to directly target the 3' untranslated region (UTR) of the Numb gene.
- Exogenous expression of miR-31/96/182 enhanced HNSCC cell migration and invasion, effects reversed by Numb expression.
Conclusions:
- miR-31, miR-96, and miR-182 are frequently and coordinately upregulated in HNSCC.
- These miRNAs act as oncogenes by co-targeting Numb, thereby promoting HNSCC progression.
- The findings highlight a novel miRNA-Numb axis in HNSCC development.
