gEAR: Gene Expression Analysis Resource portal for community-driven, multi-omic data exploration

Nature Methods volume 18, pages 843–844 (2021)Cite this article

Subjects

The gEAR portal provides a single platform for data deposition, display, analysis and interrogation, with a focus on allowing users to customize the site and their own data displays. The gEAR portal supports uploaded datasets for a range of organisms, including human, mouse, rat, zebrafish, chicken and marmoset. Multiple datasets can be displayed side-by-side within a display profile, showing not only a user’s own data in a visual form of choice, but also allowing the user to select from hundreds of previously uploaded public datasets to display alongside their own for cross-experimental validation and discovery. Integration of the Epiviz4 tool allows epigenetic modifications to be viewed in the context of gene expression. The portal is also designed to display a gene’s species-specific annotation and links out to information on other systems such as the UCSC Genome Browser5, CCDS6, Ensembl7, OMIM8, and a variety of domain-specific resources. Further features available via drop-down menus include links to the raw data in the Gene Expression Omnibus (GEO)2, the associated publication, a tool to compare gene expression across conditions, a tool to store and export gene lists for downstream analysis of differentially expressed genes, and a single-cell RNA-seq Analysis Workbench.
