Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term proteomics...

Background:

  • Metabolomics enables quantitative measurement of small organic molecules in biological samples.
  • High-throughput metabolomics technologies are increasingly used in drug testing and epidemiological studies.
  • Interpreting large metabolomics datasets in relation to sample phenotypes presents significant challenges.

Purpose of the Study:

  • To develop a computational tool, metaP-server, for automated and standardized analysis of quantitative metabolomics data.
  • To facilitate the biological interpretation of complex metabolomics datasets.
  • To provide researchers with an accessible platform for exploring metabolomics data in the context of sample phenotypes.

Main Methods:

  • Automated data quality checks and assessment of reproducibility and batch effects.
  • Statistical analyses including hypothesis and correlation tests for categorical and metric phenotypes.
  • Principal Component Analysis (PCA) and metabolite mapping onto KEGG pathways.
  • Interactive visualization tools with cross-linking to databases (HMDB, LipidMaps, KEGG, PubChem, CAS).

Main Results:

  • metaP-server provides a comprehensive pipeline from data acquisition to biological interpretation.
  • The server enables interactive exploration of data through clickable graphical outputs and phenotype-based coloring.
  • Automated analysis addresses challenges in interpreting large-scale metabolomics data.

Conclusions:

  • metaP-server is a valuable, freely accessible resource for researchers working with quantitative metabolomics data.
  • The tool enhances the biological interpretation of metabolomics results, particularly in association studies.
  • Facilitates data-driven discovery by integrating statistical analysis, visualization, and pathway mapping.
