ExoCarta is a comprehensive database detailing the molecular contents of small extracellular vesicles (sEVs), including proteins, RNA, and lipids. This resource aids researchers in understanding sEV roles in health and disease.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Bioinformatics

Background:

  • Small extracellular vesicles (sEVs) are vital for intercellular communication, carrying molecular cargo reflecting cellular states.
  • Understanding sEV molecular composition is key to deciphering their roles in health and disease.

Purpose of the Study:

  • To present ExoCarta, a web-based compendium of molecular data from small extracellular vesicles (sEVs).
  • To provide a comprehensive resource for researchers studying sEVs.

Main Methods:

  • Compilation of data from 1249 published and unpublished sEV studies.
  • Inclusion of DNA, RNA, protein, and lipid content, with quantitative data.
  • Development of a quantitative plugin (QUANT) for comparative analysis.

Main Results:

  • ExoCarta version 1.0 contains 119,489 protein, 15,868 RNA, and 3,946 lipid entries.
  • Quantitative data available for 24,073 entries, enabling cross-study comparisons.
  • Integrated Gene Ontology annotations, reactome pathways, and protein-protein interaction networks.

Conclusions:

  • ExoCarta serves as an invaluable, freely accessible resource for the small extracellular vesicle research community.
  • The database facilitates the exploration of sEV molecular cargo and its implications in various biological contexts.
  • Regular updates and integrated tools enhance its utility for global researchers.
