CistromeMap: a knowledgebase and web server for ChIP-Seq and DNase-Seq studies in mouse and human.

Area of Science:

• Genomics
• Epigenetics
• Bioinformatics

Background:

• Gene expression is tightly regulated by transcription factors and chromatin modifiers.
• Histone modifications are crucial epigenetic marks influencing gene accessibility and activity.
• Publicly available ChIP-Seq and DNase-Seq datasets are valuable resources for studying these regulatory mechanisms.

Purpose of the Study:

• To create a centralized, comprehensive, and user-friendly web server for accessing and analyzing ChIP-Seq and DNase-Seq data.
• To consolidate publicly available mouse and human epigenomic data for easier research.
• To facilitate the study of transcription regulation and chromatin dynamics.

Main Methods:

• Compilation and curation of publicly available ChIP-Seq and DNase-Seq datasets for human and mouse.
• Development of a web server interface with a user-friendly display matrix.
• Manual curation of metadata to ensure data consistency and accurate annotation.
• Inclusion of summary statistics for analyzed datasets.

Main Results:

• Established CistromeMap, a comprehensive web server knowledgebase.
• Integrated a large volume of human and mouse ChIP-Seq and DNase-Seq data.
• Provided consistent metadata and a navigable display matrix for efficient data retrieval.
• Offered summary statistics for all integrated studies.

Conclusions:

• CistromeMap serves as a valuable resource for researchers studying gene expression regulation.
• The curated knowledgebase and user-friendly interface streamline the analysis of epigenomic data.
• This resource supports further investigation into the roles of transcription and chromatin regulators.
