This study shows that a comprehensive circulating microRNA (miRNA) profile from dog plasma, analyzed using next-generation sequencing (NGS) and automated machine learning (autoML), can effectively screen for diseases. The developed diagnostic model achieved high sensitivity and specificity, indicating potential as a blood biomarker.
Area of Science:
- Veterinary Medicine
- Genomics
- Biomarker Discovery
Background:
- Utility of circulating microRNA (miRNA) profiles for disease identification in veterinary medicine using next-generation sequencing (NGS) is not well-established.
- Need for advanced diagnostic tools in companion animal health.
Purpose of the Study:
- To integrate NGS technology with automated machine learning (autoML) for comprehensive circulating miRNA profiling in dogs.
- To assess the clinical utility of an autoML-derived disease-screening model based on these miRNA profiles.
Main Methods:
- Collected plasma samples from 254 diseased dogs (including tumors) and 91 healthy dogs.
- Performed comprehensive miRNA analysis using NGS (one million reads per sample).
- Applied autoML to develop and select the highest-performing diagnostic model.
Main Results:
- The miRNA-based diagnostic model achieved an Area Under the Curve (AUC) of 0.89.
- Demonstrated high sensitivity (85%) and specificity (88%) for disease detection.
- Indicated that comprehensive miRNA profiles in dog plasma can serve as sensitive blood biomarkers.
Conclusions:
- A comprehensive circulating miRNA profile, analyzed via NGS and autoML, shows significant potential for disease screening in dogs.
- The developed diagnostic model exhibits high sensitivity, suggesting its utility as an effective screening test.
- Circulating miRNA profiles represent a promising, highly sensitive blood biomarker for canine disease diagnosis.
