The National Center for Biotechnology Information (NCBI) Epigenomics resource offers a vast collection of whole-genome epigenetic data. This public repository is continuously updated with new features and data for easier analysis and integration with other biological databases.
Area of Science:
- Genomics
- Epigenetics
- Bioinformatics
Background:
- The National Center for Biotechnology Information (NCBI) Epigenomics resource serves as a public repository for whole-genome epigenetic data.
- It is curated from the Gene Expression Omnibus (GEO) database, with specialized review and annotation.
Purpose of the Study:
- To present an updated overview of the NCBI Epigenomics resource, highlighting recent improvements and expanded data holdings.
- To detail enhancements in usability, functionality, data accessibility, and integration with other NCBI databases.
Main Methods:
- Selection and curation of epigenetics-specific data from the Gene Expression Omnibus (GEO).
- Implementation of user feedback for continuous improvement of the resource's interface and tools.
- Enhancement of data track visualization, download options, and preliminary analysis capabilities.
- Integration with other NCBI resources like the Gene database and PubMed.
Main Results:
- The resource now contains over 3700 data tracks from 955 biological sources across five species.
- Significant usability improvements have been made to the user interface and data identification.
- New tools for preliminary data analysis have been developed.
- Enhanced integration with other NCBI databases facilitates a more cohesive research experience.
Conclusions:
- The NCBI Epigenomics resource has substantially grown and improved, offering a valuable, user-friendly platform for accessing and analyzing whole-genome epigenetic data.
- Continued development based on user testing ensures the resource remains a vital component of the epigenomics research community.
