Metabolomics, the study of metabolites, helps identify functions of unknown genes and discover diagnostic biomarkers. This high-throughput, cost-effective approach complements other

Area of Science:

  • Life Sciences
  • Systems Biology
  • Genomics

Background:

  • Limited knowledge of gene function (30-40% of open reading frames are orphans).
  • Need for identifying functions of orphan genes for potential therapeutic targets.
  • Growing demand for diagnostic biomarkers (mRNA, proteins, metabolites) for disease monitoring and treatment response.

Purpose of the Study:

  • Provide an overview of metabolomics.
  • Discuss its complementary role with transcriptomics and proteomics in systems biology.
  • Highlight methods for metabolome analysis and data interpretation.

Main Methods:

  • Overview of metabolomics techniques.
  • Discussion of data analysis for complex metabolomic datasets.
  • Inclusion of non-invasive footprinting analysis for in vitro cell systems.

Main Results:

  • Metabolomics offers a high-throughput and cost-effective approach.
  • It complements transcriptomics and proteomics within systems biology.
  • Enables identification of metabolic pathways affected by biotic or abiotic stresses.

Conclusions:

  • Metabolomics is crucial for understanding orphan gene function and discovering biomarkers.
  • It integrates with transcriptomics and proteomics for a holistic systems biology approach.
  • Its cost-effectiveness and throughput make it suitable for large-scale stress studies in various organisms.
