Protocol for parallel proteomic and metabolomic analysis of mouse intervertebral disc tissues

Area of Science:

• Biochemistry
• Molecular Biology
• Biomedical Engineering

Background:

• Omics technologies offer comprehensive molecular insights into complex diseases.
• Standardized protocols are crucial for reproducible and comparable multi-group research findings.
• Musculoskeletal pathologies, like intervertebral disc (IVD) degeneration, require advanced molecular understanding.

Purpose of the Study:

• To describe a novel, standardized protocol for parallel proteomic and metabolomic analysis of murine intervertebral disc (IVD) tissues.
• To optimize "omics" applications using mouse models, addressing challenges of small sample size and tissue composition.
• To facilitate biomarker discovery and therapeutic target development for chronic diseases.

Main Methods:

• Detailed protocol for dissection of murine IVD tissues.
• Sample isolation techniques optimized for small tissue quantities.
• Integrated data analysis strategies for parallel proteomics and metabolomics.

Main Results:

• Successfully optimized a protocol for parallel omics analysis on limited murine IVD samples.
• Addressed challenges associated with small sample size and extracellular matrix-rich tissues.
• Established a reproducible method for comprehensive molecular profiling of IVD tissues.

Conclusions:

• The developed protocol enables robust parallel proteomic and metabolomic analysis of mouse IVD tissues.
• Standardization advances the application of omics technologies in musculoskeletal disease research.
• This method supports biomarker identification and therapeutic target development for chronic diseases.
