Modulating CRISPR/Cas9 genome-editing activity by small molecules

Area of Science:

• Molecular Biology
• Biotechnology
• Genetics

Background:

• CRISPR/Cas9 gene editing is a key tool for DNA modification in research and medicine.
• Current limitations include low precise gene modification efficiency and prolonged, uncontrolled Cas9 activity.
• Overcoming these challenges is crucial for expanding CRISPR/Cas9's therapeutic applications.

Purpose of the Study:

• To review small molecules that can precisely modulate CRISPR/Cas9 genome editing activity.
• To discuss the mechanisms of action for these small molecules.
• To identify potential therapeutic strategies for enhancing CRISPR/Cas9 precision.

Main Methods:

• Literature review of small molecules targeting CRISPR/Cas9 activity.
• Analysis of mechanisms of action for small-molecule modulators.
• Evaluation of clinical potential for precise gene editing regulation.

Main Results:

• Small molecules offer potential for precise control over CRISPR/Cas9 activity.
• Direct-acting small molecules show promise for regulating Cas9 activity.
• These modulators can enhance gene modification efficiency and control Cas9 duration.

Conclusions:

• Small molecules are valuable tools for fine-tuning CRISPR/Cas9 genome editing.
• Direct-acting small molecules are particularly suitable for precise Cas9 regulation.
• Findings aid in discovering novel small-molecule enhancers and inhibitors for CRISPR/Cas9 systems.
