CRISPR-based methods for high-throughput annotation of regulatory DNA

Area of Science:

• Genomics
• Molecular Biology
• Epigenetics

Background:

• Conventional screening methods primarily target the protein-coding genome using technologies like RNA interference (RNAi).
• Functional analysis of the non-coding genome has been limited due to a lack of equivalent high-throughput perturbation technologies.
• Recent advancements have introduced CRISPR-based screening for comprehensive genomic analysis.

Purpose of the Study:

• To review recent progress in assigning function to the non-coding genome.
• To discuss the application of CRISPR-based genomic and epigenomic screens.
• To explore the potential of these technologies in advancing our understanding of genome structure and regulation.

Main Methods:

• CRISPR/Cas9-based screening of genomic DNA.
• CRISPR-based genomic screens for gene function.
• CRISPR-based epigenomic screens for regulatory element function.

Main Results:

• CRISPR-based screening enables high-throughput perturbation of both coding and non-coding genomic elements.
• These methods facilitate the functional characterization of non-coding gene regulatory elements.
• Significant progress has been made in assigning function to previously uncharacterized non-coding regions.

Conclusions:

• CRISPR-based technologies represent a paradigm shift in functional genome screening.
• These tools are crucial for dissecting the regulatory roles of the non-coding genome.
• Future applications promise to transform our understanding of genome structure and complex regulatory networks.
