Alternative splicing as a therapeutic target for human diseases

Area of Science:

• Molecular Biology
• Genetics
• Biotechnology

Background:

• Alternative splicing generates diverse protein isoforms from a single eukaryotic gene.
• Defective pre-mRNA splicing can lead to non-functional or toxic proteins, impacting cell homeostasis.
• Targeted gene regulation is crucial for understanding gene function and developing therapeutics.

Purpose of the Study:

• To present two RNA-based molecular tools for gene expression regulation.
• To demonstrate applications in loss-of-function and splicing modulation.
• To highlight their potential in studying gene function and drug discovery.

Main Methods:

• RNA interference (RNAi) for gene silencing (loss-of-function).
• Theophylline-responsive riboswitches for modulating alternative splicing.
• In vitro and/or in vivo experimental validation of these RNA-based strategies.

Main Results:

• Successful demonstration of RNAi for effective gene silencing.
• Effective regulation of alternative splicing using theophylline-responsive riboswitches.
• Validation of these RNA tools for studying gene function and disease mechanisms.

Conclusions:

• RNAi and riboswitches are versatile tools for gene expression control.
• These strategies offer therapeutic potential for diseases linked to splicing defects.
• Continued development of these RNA-based approaches will advance gene function studies and drug discovery.
