Area of Science:

  • Cardiovascular Pharmacology
  • Systems Biology
  • Bioinformatics

Background:

  • Vasodilation is crucial for managing cardiovascular diseases like hypertension.
  • Developing effective vasodilators is a key therapeutic goal.
  • Systematic exploration of vasodilators remains limited.

Purpose of the Study:

  • To establish a transcriptome-based functional gene module reference approach for identifying novel vasodilators.
  • To systematically screen for compounds with vasorelaxant effects.
  • To accelerate the development of new therapeutic agents for cardiovascular conditions.

Main Methods:

  • Curated two functional gene modules regulating vascular diameter.
  • Collected and analyzed gene expression profiles from herbal component treatments.
  • Employed gene set enrichment analysis to evaluate module correlations.
  • Predicted and ranked candidate compounds based on a defined index.
  • Experimentally validated top candidates using aortic ring assays.

Main Results:

  • Successfully developed a novel transcriptome-based approach for vasodilator discovery.
  • Identified and ranked potential vasorelaxant compounds.
  • Experimental validation confirmed the vasorelaxant effects of top-ranked candidates.
  • Demonstrated the efficacy of the integrated strategy in identifying novel vasodilators.

Conclusions:

  • The developed gene module reference approach offers a systematic method for discovering vasodilators.
  • This strategy integrates multi-omics data and experimental validation for drug development.
  • The findings pave the way for novel therapeutic opportunities in cardiovascular disease treatment.
