Summary
Proteomics biomarker discovery for clinical use has seen limited success. This paper analyzes causes and suggests strategies focusing on cell/tissue analysis or highly selective protein selection from body fluids.
Area of Science:
- Proteomics
- Biomarker Discovery
- Clinical Applications
Background:
- Proteomics is crucial for clinical biomarker discovery, but successes remain limited.
- Significant efforts have yielded scarce results, necessitating a re-evaluation of current strategies.
Purpose of the Study:
- To analyze the primary reasons for limited success in proteomics-based biomarker discovery.
- To propose alternative strategies to overcome existing challenges in the field.
Main Methods:
- Analysis of two major strategies: shifting discovery from body fluids to cells/tissues.
- Evaluation of implementing highly selective protein selection for body fluid analysis.
Main Results:
- Identified key limitations in current proteomics biomarker discovery approaches.
- Proposed alternative methodologies to enhance success rates and clinical utility.
Conclusions:
- Current proteomics biomarker discovery strategies require significant revision.
- Focusing on cellular/tissue-based discovery or advanced body fluid analysis may improve clinical outcomes.
