miRMaid

miRMaid integrates and unifies microRNA (miRNA) data resources centered on miRBase to enable computational integration and querying of miRNA annotations across species.

Key Features:

• Integration of centralized and decentralized resources: Consolidates miRBase data (as of version 14.0 includes over 10,000 miRNA precursors from 115 species) with additional decentralized online miRNA annotations and information.
• Modular plugin architecture: Supports integration of third-party miRNA data sources through a plugin system for flexible dataset expansion and customization.
• Web service interface: Exposes miRBase and integrated resources via interconnected uniform web services for programmatic querying and data access.
• Custom tool development framework: Provides a platform for bioinformaticians to develop custom miRNA analysis tools and data sources.

Scientific Applications:

• Post-transcriptional regulation studies: Enables analysis of miRNA involvement in regulating gene expression at the post-transcriptional level.
• Comparative cross-species analyses: Facilitates comparative studies of miRNA sequences and annotations across multiple species.
• miRNA interaction discovery: Supports identification and exploration of novel miRNA interactions and annotations.
• Physiological and pathological investigation: Allows exploration of miRNA roles in diverse physiological states and disease contexts.

Methodology:

Uses a uniform web service interface for data integration and querying, aligns integrated content with official miRBase releases, and incorporates additional data sources via a modular plugin architecture.
