MicroRNA Dynamics in Head and Neck Squamous Cell Carcinoma

Head and neck squamous cell carcinoma (HNSCC) represents a heterogeneous group of malignancies arising from the mucosal linings of the oral cavity, oropharynx, larynx and related sites. MicroRNAs (miRNAs) are short, non-coding RNAs that regulate gene expression by binding target messenger RNAs and promoting their degradation or translational repression. In HNSCC, aberrant miRNA expression contributes to tumour initiation and progression by modulating key pathways involved in cell proliferation, apoptosis, migration, invasion, angiogenesis and resistance to therapy. Distinct miRNA profiles have been identified in tissue biopsies, circulating fluids and even exfoliated cells, offering insights into disease subtypes, prognostic groups and therapeutic vulnerabilities. Network analyses reveal that oncogenic miRNAs (oncomiRs) and tumour-suppressor miRNAs often converge on shared molecular circuits governing epithelial–mesenchymal transition, DNA-damage response and immune surveillance. Together, these findings underscore the global significance of miRNA dynamics as both biomarkers for early detection and as molecular levers for the development of bespoke treatments, including synthetic miRNA mimics, antagonists and nanotechnology-based delivery systems.

Research from Nature Portfolio

Recent studies have elucidated the tumour-suppressive role of miR-6510-3p in HNSCC. Tumour specimens exhibit marked downregulation of miR-6510-3p compared with adjacent normal tissues, a pattern associated with poorer survival. Restoring miR-6510-3p levels in cancer cell lines induces G2/M cell-cycle arrest, reduces proliferation and migration, promotes apoptosis and diminishes colony-forming capacity. Moreover, miR-6510-3p reconstitution enhances sensitivity to ionising radiation and impairs cancer stem-cell phenotypes linked to metastatic potential and relapse. These findings highlight miR-6510-3p as both a prognostic marker and a candidate for miRNA-based therapeutic interventions.

Technical terms

MicroRNA (miRNA): A small (≈22 nucleotides), non-coding RNA molecule that post-transcriptionally regulates gene expression by binding complementary sequences in target mRNAs.

OncomiR: A microRNA whose overexpression contributes to oncogenesis by downregulating tumour-suppressor genes.

Tumour-suppressor microRNA: A microRNA that inhibits tumour development by targeting oncogenic mRNAs.

Liquid biopsy: A minimally invasive method that analyses circulating tumour-derived nucleic acids or cells in body fluids for diagnostic or prognostic purposes.

Circular carrier (nanocarrier): A nano-scale vehicle designed to deliver therapeutic agents, such as miRNA mimics or inhibitors, directly to tumour cells.

Epithelial–mesenchymal transition (EMT): A biological process by which epithelial cells acquire mesenchymal traits, enhancing migratory capacity and invasiveness.
