Summary
MicroRNAs (miRs) are key in head and neck squamous cell carcinoma (HNSCC) development. Salivary miRs offer a promising noninvasive method for HNSCC diagnosis and prognosis.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- MicroRNAs (miRs) are small noncoding RNAs regulating gene expression.
- Dysregulation of miRs is implicated in various cancers, including head and neck squamous cell carcinoma (HNSCC).
- Human papillomavirus (HPV) infection is associated with a subset of HNSCC, influencing miR profiles.
Purpose of the Study:
- To investigate the role of miRs in HNSCC pathogenesis.
- To explore the differences in miR expression between HPV-positive and HPV-negative HNSCC.
- To assess the potential of salivary miRs as noninvasive biomarkers for HNSCC detection and prognosis.
Main Methods:
- Analysis of miR expression profiles in HNSCC tissues and saliva.
- Comparison of miR profiles in HPV-positive versus HPV-negative HNSCC.
- Evaluation of salivary miRs for diagnostic and prognostic potential.
Main Results:
- Altered miR expression is observed during the transition from dysplasia to carcinoma in HNSCC.
- HPV-positive HNSCC exhibits distinct salivary miR profiles compared to HPV-negative HNSCC due to viral modulation.
- Salivary miRs show promise as noninvasive biomarkers for HNSCC.
Conclusions:
- MiRs play a significant role in HNSCC development and progression.
- Salivary miR analysis represents a viable noninvasive approach for HNSCC diagnosis and prognosis.
- MiRs may also aid in surgical margin assessment and represent therapeutic targets.

3.1K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

7.5K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

4.0K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
