RuleGO

RuleGO describes gene groups using logical rules that combine Gene Ontology (GO) terms to annotate and interpret genome-wide expression profiles from DNA microarray technology.

Key Features:

• Logical-rule generation: Creates logical rules that use Gene Ontology (GO) terms as premises to describe gene groups.
• GO-based annotation: Annotates genes using GO aspects including biological processes, cellular components, and molecular functions.
• Automatic ontology-level adjustment: Automatically adjusts the ontology level used in generated rules.
• Control of coappearing GO terms: Automatically adjusts the number of coappearing GO terms included in rules.
• Parameterizable rule scope: Allows definition of the scope of potential solutions via user-set parameters guiding rule generation.
• Microarray data support: Applies to genome-wide expression profiles derived from DNA microarray technology.
• Pattern and relationship detection: Identifies patterns and relationships among genes through rule-based descriptions.

Scientific Applications:

• Functional annotation of gene sets: Provides GO-based functional descriptions for gene groups derived from expression data.
• Interpretation of microarray experiments: Assists in translating genome-wide DNA microarray results into biologically relevant conclusions.
• Discovery of gene co-occurrence patterns: Detects sets of GO terms that coappear across gene groups, highlighting shared characteristics.
• Integration with annotation databases: Leverages GO annotations to enhance analysis workflows that use external annotation databases.

Methodology:

Generates logical rules describing gene groups using Gene Ontology (GO) terms as premises, automatically adjusts ontology level and the number of coappearing GO terms, and uses user-set parameters to guide rule generation for analysis of genome-wide expression profiles from DNA microarray technology.
