Salivary extracellular noncoding RNA: emerging biomarkers for molecular diagnostics

Area of Science:

• Biomolecular analysis
• Translational medicine
• Molecular diagnostics

Background:

• Saliva contains circulatory molecules and unique constituents for disease detection.
• Noncoding RNAs (ncRNAs) are crucial regulators in oncogenesis and tumor progression.
• ncRNAs are stable in body fluids like saliva, resisting degradation.

Purpose of the Study:

• To review the current status and clinical implications of ncRNAs in human saliva.
• To explore the translational applications of salivary ncRNAs for disease screening.
• To highlight ncRNAs as emerging biomarkers for noninvasive disease detection.

Main Methods:

• Literature review of studies on salivary ncRNAs.
• Analysis of ncRNA stability and roles in disease.
• Evaluation of translational potential for clinical diagnostics.

Main Results:

• Salivary ncRNAs show potential for discriminating oral and systemic diseases.
• ncRNA profiles can serve as noninvasive biomarkers.
• Short ncRNAs are stable and detectable in saliva.

Conclusions:

• Noninvasive salivary tests based on ncRNA profiles have significant translational value.
• ncRNAs in saliva can aid in early disease detection, reducing healthcare costs.
• Salivary ncRNAs represent promising biomarkers for future clinical applications.
