Super-enhancers are a large cluster of transcriptionally active enhancers enriched in enhancer-associated chromatin characteristics. Compared to typical enhancers, super-enhancers are larger, exhibit higher transcription factor density, and are frequently associated with key lineage-specific genes that control cell state and differentiation in somatic cells.
Here, we developed a comprehensive human super-enhancer database (SEdb, http://www.licpathway.net/sedb) that aimed to provide a large number of available resources on human super-enhancers. The database was annotated with potential functions of super-enhancers in the gene regulation. The current version of SEdb documented a total of 331,601 super-enhancers from 542 samples. Furthermore, SEdb provides detailed genetic and epigenetic annotation information on super-enhancers. Information includes common SNPs, motif changes, expression quantitative trait locus (eQTL), risk SNPs, transcription factor binding sites (TFBSs), CRISPR/Cas9 target sites and DNase I hypersensitivity sites (DHSs) for in-depth analyses of super-enhancers. SEdb will help elucidate super-enhancer-related functions and find potential biological effects.
Browse sample information:The ‘Data-Browse’ page is an interactive and alphanumerically sortable table that allows users to quickly search for samples and customize filters using ‘Data sources’, ‘Biosample type’, ‘Tissue type’ and ‘Biosample name’. To view super-enhancers for a given sample, users click on ‘Sample ID’.
Query super-enhancer:Based on the tissue query, users can query the super-enhancer for all samples of a particular type of tissue. In the gene-based query, users can query a gene of interest and SEdb will return all super-enhancers that match the super-enhancer-gene relationship for all samples. In the sample-based advanced query, users determine the scope of the super-enhancer query by determining the sample and genome location for the results of interest.
Super-enhancer details:In addition to general information about the super-enhancer, SEdb lists more detailed annotation information including common SNPs, eQTLs, risk SNPs, TFBSs, CRISPR/Cas9 target sites, DHSs and enhancers.
