Metabolomic Applications in Radiation Biodosimetry

Area of Science:

• Biochemistry
• Analytical Chemistry
• Toxicology

Background:

• Metabolomics enables the assessment and quantification of small molecules in biological samples.
• This approach is valuable for evaluating exposure to genotoxic stressors, including ionizing radiation.
• Radiation biodosimetry requires reliable methods for assessing radiation exposure levels.

Purpose of the Study:

• To present standardized protocols for sample preparation in metabolomics.
• To facilitate the analysis of biological samples using high-throughput liquid chromatography-mass spectrometry (HT-LC-MS).
• To support the application of metabolomics in radiation biodosimetry.

Main Methods:

• Protocols for routine sample preparation from rodents to patients are detailed.
• Methods are optimized for high-throughput liquid chromatography-mass spectrometry (HT-LC-MS) analysis.
• Focus is on general metabolite profiling rather than specific metabolite classes.

Main Results:

• Established laboratory protocols for sample preparation are presented.
• The protocols are suitable for general metabolomic profiling.
• The methods are validated for use in radiation biodosimetry.

Conclusions:

• The presented protocols provide a foundation for metabolomic analysis in radiation biodosimetry.
• These methods allow for the evaluation of ionizing radiation and genotoxic stressor exposure.
• The study facilitates the routine application of metabolomics in clinical and research settings for exposure assessment.
