CRISPR-based Transcriptional Regulation: Technologies, Applications, and Future Directions

Area of Science:

• Biotechnology
• Molecular Biology
• Gene Therapy

Background:

• CRISPR activation (CRISPRa) and CRISPR interference (CRISPRi) are advanced tools for precise gene expression control.
• These technologies utilize modified CRISPR-Cas systems for targeted gene upregulation (CRISPRa) or silencing (CRISPRi).

Purpose of the Study:

• To review the advancements and therapeutic potential of CRISPRa and CRISPRi technologies.
• To highlight their application in various disease models and ongoing clinical trials.

Main Methods:

• Utilizing nuclease-inactive Cas proteins fused with transcriptional activators (CRISPRa) or repressor domains (CRISPRi).
• Employing guide RNAs for specific targeting of genes for activation or interference.
• Evaluating preclinical data and clinical trial outcomes for CRISPRa/i therapies.

Main Results:

• CRISPRa/i have shown efficacy in preclinical models of metabolic, neurological, muscular, and oncological diseases.
• CRISPRi therapies are in clinical trials for hepatitis B and muscular dystrophy, demonstrating positive safety and efficacy.
• Ongoing innovations are improving the precision and safety of CRISPR-based gene regulation.

Conclusions:

• CRISPRa and CRISPRi represent significant progress in gene and epigenetic therapy.
• These technologies are expected to revolutionize the treatment of genetic and epigenetic disorders.
