Summary
Clinical proteomics advances offer new diagnostic tools but face challenges in standardization. Focusing on cellular proteomics (cytoproteomics) and quality control is crucial for reliable clinical implementation and improved patient care.
Area of Science:
- Biochemistry
- Molecular Biology
- Clinical Diagnostics
Background:
- Proteomics technology is rapidly advancing, enabling new clinical applications like biomarker identification and disease monitoring.
- Challenges remain due to the complexity and dynamic range of human body fluid proteomes, alongside issues in quantitation and standardization.
- Cytomics, linked with proteomics, offers functional cell analysis and bioinformatic approaches for novel cellular proteomic biomarkers.
Purpose of the Study:
- To discuss recent advances in clinical proteomics, focusing on cellular proteomics (cytoproteomics).
- To highlight the importance of preanalytical and analytical standardization and quality control for routine laboratory testing.
- To emphasize the need for clinical studies to validate these techniques for diagnostic strategies and clinical decision-making.
Main Methods:
- Review of recent developments in proteomics technologies, including advanced spectrometry and protein array formats.
- Discussion of challenges in the preanalytical phase, such as sample collection, preparation, and storage, and their impact on results.
- Exploration of bioinformatic approaches for identifying cellular proteomic biomarkers and their release products.
Main Results:
- Proteomics technologies are nearing a standard suitable for clinical diagnostics.
- Preanalytical variables significantly influence proteomics study results, similar to clinical chemistry.
- Standardization of preanalytical and analytical phases, along with quality control, is essential for clinical implementation.
Conclusions:
- Clinical proteomics, particularly cytoproteomics, holds significant potential for patient stratification, therapeutic monitoring, and prognosis prediction.
- Addressing preanalytical and analytical standardization is critical before widespread clinical adoption.
- Further clinical studies are necessary to validate novel diagnostic strategies and their impact on clinical decision-making.
