BedSect: An Integrated Web Server Application to Perform Intersection, Visualization, and Functional Annotation of...

Area of Science:

• Genomics
• Bioinformatics
• Computational Biology

Background:

• Genomic region analysis, including transcription factor binding sites (TFBSs), is crucial for biological research.
• Existing command-line tools lack integrated visualization and functional annotation capabilities.
• There is a need for a user-friendly webserver for genomic region intersection analysis.

Purpose of the Study:

• To introduce BedSect, a comprehensive and user-friendly webserver application.
• To enable identification, visualization, and functional annotation of intersecting genomic regions.
• To facilitate the analysis of datasets from user uploads or the Gene Transcription Regulation Database (GTRD).

Main Methods:

• Developed BedSect, an integrated webserver application.
• Implemented intersection analysis with UpSet plots and correlation plots via a Shiny application.
• Integrated the GREAT tool for functional annotation, gene ontology, and pathway enrichment analysis.
• Provided UCSC Genome Browser integration for custom track visualization.

Main Results:

• BedSect successfully performs intersection analysis on genomic regions.
• The webserver generates publication-ready UpSet and correlation plots for visualization.
• Functional annotation, gene ontology, and pathway enrichment analyses are readily performed.
• Users can visualize results in the UCSC Genome Browser.

Conclusions:

• BedSect offers a comprehensive solution for analyzing and visualizing genomic region intersections.
• The webserver simplifies complex analyses, making them accessible to a wider range of researchers.
• BedSect enhances the study of transcription factor binding sites and other genomic elements.
