Area of Science:

• Genomics
• Molecular Biology
• Biotechnology

Background:

• Thousands of long non-coding RNAs (lncRNAs) have been identified, but their functions remain largely unknown.
• Challenges in studying lncRNAs include low expression, tissue specificity, and poor cross-species conservation.
• Limited methodologies previously hindered functional characterization of lncRNAs.

Purpose of the Study:

• To review CRISPR-based strategies for characterizing long non-coding RNAs (lncRNAs).
• To highlight the potential of CRISPR technology in exploring the non-coding genome.
• To discuss future applications of these methods in understanding lncRNA functions.

Main Methods:

• CRISPR/Cas9 technology enables targeted modification and high-throughput analysis of lncRNA loci.
• CRISPR-based approaches include sequence modification, transcriptional modulation, and epigenetic alterations.
• Programmable Cas proteins offer enhanced precision for targeting RNA molecules, facilitating knock-down and characterization.

Main Results:

• CRISPR strategies have been successfully applied to characterize lncRNAs with significant biological roles.
• These methods provide powerful tools for dissecting the genetic and functional aspects of lncRNAs.
• Advancements in CRISPR technology expand the scope for studying the non-coding genome.

Conclusions:

• CRISPR-based technologies are crucial for advancing our understanding of long non-coding RNA (lncRNA) functions.
• These innovative approaches are essential for comprehensive exploration of the non-coding genome.
