This study introduces an evolution-strengthened knowledge graph (ESKG) to identify disease-causing genes for drug discovery. The GraphEvo model leverages evolutionary insights for predicting gene targetability and druggability, accelerating the identification of promising drug targets.
Area of Science:
- Biomedical Informatics
- Computational Biology
- Drug Discovery
Background:
- Identifying disease-causing genes is crucial for drug discovery.
- Disease pathogenesis is linked to organismal evolutionary events.
- Knowledge graphs (KGs) integrate vast biomedical data.
Purpose of the Study:
- To construct an evolution-strengthened knowledge graph (ESKG).
- To develop a machine learning model (GraphEvo) for predicting gene targetability and druggability.
- To validate the application of ESKG in identifying causative genes and promising drug targets.
Main Methods:
- Construction of an evolution-strengthened knowledge graph (ESKG).
- Development of the GraphEvo machine learning model based on ESKG.
- Analysis of evolutionary hallmarks for explainability in druggability prediction.
Main Results:
- Successfully constructed an ESKG integrating evolutionary knowledge.
- GraphEvo demonstrated effective prediction of gene targetability and druggability.
- ESKG provides explainability for druggability predictions based on evolutionary factors.
Conclusions:
- Evolutionary knowledge significantly enhances causative gene identification for drug discovery.
- The ESKG and GraphEvo model offer a powerful approach for identifying promising drug targets.
- This study underscores the value of integrating evolutionary insights into biomedical data analysis.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
