How to Illuminate the Druggable Genome Using Pharos

Area of Science:

• Bioinformatics
• Drug Discovery
• Genomics

Background:

• The Illuminating the Druggable Genome (IDG) Knowledge Management Center aggregates vast biological data.
• Identifying novel drug targets is crucial for advancing pharmaceutical research and development.
• Existing resources often lack comprehensive analysis of less-studied proteins.

Purpose of the Study:

• To introduce Pharos, an integrated web-based informatics platform.
• To facilitate the analysis of aggregated data from the IDG Knowledge Management Center.
• To aid researchers in identifying and validating novel drug targets, including understudied proteins.

Main Methods:

• Pharos integrates data from over 60 high-quality resources.
• Utilizes text indexing to uncover hidden connections between biological targets.
• Employs a knowledge-based classification system for ranking proteins.
• Provides protocols for target searching, filtering, and analyzing "dark" targets.

Main Results:

• The Pharos platform (as of October 2019) covers 20,244 human proteins, 19,880 disease associations, and 226,829 compounds.
• Identifies connections between targets and disease/phenotype data.
• Enables researchers to discover and prioritize understudied "dark" targets.
• Demonstrates varying levels of available knowledge for different protein targets.

Conclusions:

• Pharos serves as a valuable resource for drug discovery and target validation.
• The platform accelerates target identification by consolidating and analyzing diverse biological data.
• By highlighting "dark" targets, Pharos opens new avenues for therapeutic development.
• Enhanced knowledge of understudied proteins can lead to novel drug discovery opportunities.
