[Identification and mapping of cis-regulatory elements within long genomic sequences]

Area of Science:

• Genomics
• Molecular Biology
• Bioinformatics

Context:

• Genome sequencing provides a foundation for analyzing regulatory elements.
• Experimental data on the location of genomic regulatory elements (enhancers, silencers, etc.) is limited at the whole-genome level.
• In silico prediction of gene-, tissue-, or cell-specific regulatory elements is often ambiguous.

Purpose:

• To discuss novel high-throughput experimental approaches for identifying mammalian cis-regulatory elements.
• To address the need for experimental validation of predicted regulatory elements.
• To facilitate comprehensive genome annotation.

Summary:

• The review covers innovative experimental techniques for the high-throughput identification and mapping of cis-regulatory elements in mammalian genomes.
• It highlights the limitations of current experimental data and in silico prediction methods.
• The focus is on developing scalable methods for discovering functional genomic regions.

Impact:

• Enables more accurate and complete genome annotation.
• Advances the understanding of gene regulation across different cell types and tissues.
• Provides a foundation for future functional genomics studies and therapeutic target identification.
