Background:

  • Alternative splicing is a key mechanism for generating protein diversity.
  • Understanding splicing regulation is crucial for deciphering complex biological processes and disease mechanisms.

Purpose of the Study:

  • To elucidate the complex network of alternative splicing events in Drosophila.
  • To identify small molecules that specifically modulate splicing regulator activity in human cells.

Main Methods:

  • RNA interference (RNAi) was employed to silence specific splicing regulators.
  • Splicing-specific microarrays were utilized to analyze alternative splicing patterns.
  • A high-throughput screening of over 6,000 compounds was performed on human cells.

Main Results:

  • A complex network of distinct alternative splicing events was revealed in Drosophila.
  • Specific drugs were identified that directly interfere with a class of splicing regulators in human cells.

Conclusions:

  • These findings provide insights into the intricate regulation of alternative splicing.
  • The identified compounds represent potential therapeutic agents for diseases linked to splicing dysregulation.
