WormQTL(HD) links C. elegans expression quantitative trait loci (eQTL) data to human diseases. This database aids in discovering conserved gene networks and predicting disease-associated genes using model organism research.
Area of Science:
- Genomics
- Systems Biology
- Bioinformatics
Background:
- Protein interactions are evolutionarily conserved, enabling disease study in model organisms.
- Caenorhabditis elegans is a valuable model for molecular quantitative genetics and systems biology.
- Existing data links C. elegans quantitative trait loci (QTL) to human gene-disease associations.
Purpose of the Study:
- To develop WormQTL(HD), a database connecting C. elegans expression QTL (eQTL) data with human disease associations.
- To provide tools for identifying functionally coherent, evolutionarily conserved gene networks.
- To facilitate prediction of novel gene-gene interactions and functions for disease-related genes.
Main Methods:
- Integrated C. elegans eQTL datasets with human disease associations (OMIM, DGA, GWAS Central, NHGRI GWAS Catalogue).
- Utilized orthologous genes between C. elegans and humans to link phenotypes.
- Leveraged QTL results, molecular and classical phenotypes, and genotype data from the WormQTL database.
- Built the database using MOLGENIS and xQTL workbench, offering open-source software.
Main Results:
- Created a comprehensive database linking C. elegans eQTL data to 34,337 human gene-disease associations.
- Developed user-friendly tools for exploring conserved gene networks.
- Enabled prediction of novel gene functions and associations relevant to human diseases.
Conclusions:
- WormQTL(HD) serves as a valuable resource for comparative genomics and disease gene discovery.
- The database facilitates the use of C. elegans as a model system for understanding human disease mechanisms.
- It supports the identification of evolutionary conserved gene networks underlying diseases.
