MicroRNA Mechanisms in Oral Squamous Cell Carcinoma

Summary

MicroRNAs (miRNAs) are small non-coding RNAs of approximately 18–25 nucleotides that regulate gene expression by binding to complementary sequences in messenger RNAs, leading to translational repression or degradation. In oral squamous cell carcinoma (OSCC), aberrant miRNA expression contributes to tumour initiation, progression, metastasis and resistance to therapy. Dysregulated miRNAs may act either as oncogenes by suppressing tumour suppressor genes or as tumour suppressors by targeting oncogenic transcripts. Key pathological processes modulated by miRNAs in OSCC include cell cycle control, apoptosis, epithelial-to-mesenchymal transition (EMT), invasion and metastatic colonisation. Interactions between miRNAs and other classes of non-coding RNAs—such as long non-coding RNAs and circular RNAs—further refine these regulatory networks through competing endogenous RNA mechanisms. Beyond mechanistic insights, evolving research highlights the utility of miRNA signatures in saliva, serum and exosomes as minimally invasive biomarkers for early diagnosis, risk stratification and monitoring of recurrence. Advances in understanding miRNA-mRNA networks are paving the way for novel diagnostic tools and targeted therapies that may improve patient outcomes in this globally significant malignancy.

MicroRNA Mechanisms in Oral Squamous Cell Carcinoma publication trend

The graph below shows the total number of articles in microrna mechanisms in oral squamous cell carcinoma across all publications each year (not limited to Nature Index journals).

Technical terms

MicroRNA (miRNA): A short non-coding RNA that regulates gene expression post-transcriptionally by binding to complementary mRNA sequences.

Exosome: A small extracellular vesicle (30–150 nm) that carries proteins, lipids and RNAs, including miRNAs, for intercellular communication.

Epithelial-to-mesenchymal transition (EMT): A cellular programme by which epithelial cells acquire mesenchymal traits, increasing motility and invasive capacity.

3′-Untranslated region (3′-UTR): The segment of mRNA downstream of the coding sequence that often contains binding sites for regulatory molecules such as miRNAs.

Biomarker: A measurable indicator of a biological state or condition, used for diagnosis, prognosis or therapeutic monitoring.
