Genie

Genie prioritizes genes by evaluating biomedical literature and ortholog relationships to identify genes relevant to selected research topics across genomes.

Key Features:

• Comprehensive literature evaluation: Systematically assesses all genes within a genome and their orthologs across hundreds of species and millions of genes against a selected research topic.
• Ortholog-based prioritization: Leverages orthologous relationships to enrich and prioritize candidate genes, exemplified by enrichment of zebrafish genes involved in heart development using human and mouse orthologs.
• High precision and sensitivity: Demonstrated high precision in benchmarks, reporting up to 100% precision and outperforming other algorithms in high-sensitivity scenarios.
• Efficient processing time: Performs genome-scale literature analyses rapidly, with common run times reported below a minute even when analyzing the human genome against hundreds of thousands of literature records.

Scientific Applications:

• Developmental biology: Identification and prioritization of genes involved in developmental processes such as heart development in zebrafish using literature and ortholog evidence.
• Genomics and comparative genomics: Genome-wide ranking of genes across species to support cross-species comparisons and ortholog-based inference.
• Integration with expression data: Correlation of literature-prioritized genes with differentially expressed genes from microarray experiments to support candidate selection.
• Hypothesis generation and experimental planning: Prioritization of candidate genes for downstream experimental study and validation.

Methodology:

Analyzes biomedical literature to score and rank genes, systematically assesses genes and their orthologs against a selected topic, leverages orthologous relationships for prioritization, and correlates literature-based rankings with differential expression from microarray experiments.
