Metabolomics: an emerging post-genomic tool for nutrition

Area of Science:

• Biochemistry and Molecular Biology
• Systems Biology
• Analytical Chemistry

Background:

• The post-genomic era demands technologies to explore cellular and organismal function at the molecular level.
• Metabolomics measures global sets of low-molecular-weight metabolites, offering insights into physiological and pathological states.
• Metabolite profiles can reveal cellular control mechanisms and identify potential surrogate markers for diseases.

Purpose of the Study:

• To explore the utility of metabolomic approaches in understanding cellular control mechanisms and disease states.
• To investigate the potential of metabolomics in identifying novel surrogate markers for various pathologies.
• To highlight the application of metabolomics in studying toxicological mechanisms, disease processes, and the nutrition-metabolism relationship.

Main Methods:

• Utilizes analytical techniques such as Nuclear Magnetic Resonance (NMR) spectroscopy and Mass Spectrometry (MS) to quantify metabolites.
• Employs advanced statistical and bioinformatic tools for data analysis and interpretation of large-scale metabolomic datasets.
• Analyzes metabolite profiles in biological samples like body fluids and tissues.

Main Results:

• Metabolomic profiles serve as crucial indicators of physiological and pathological conditions.
• The approach has been successfully applied to investigate toxicological mechanisms and disease progression.
• Demonstrates potential in understanding dietary substrate metabolism, drug-induced metabolic disturbances (e.g., in type 2 diabetes mellitus), and therapeutic effects of supplements.

Conclusions:

• Metabolomics provides a comprehensive view of cellular functions and metabolic states.
• It holds significant promise for disease biomarker discovery and personalized medicine.
• Metabolomics is a valuable tool for unraveling complex interactions between nutrition, metabolism, and health outcomes.
