miRIAD-integrating microRNA inter- and intragenic data.

Area of Science:

• Genomics
• Molecular Biology
• Bioinformatics

Background:

• MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression post-transcriptionally.
• Many miRNAs reside within protein-coding genes (host genes), suggesting functional links.

Purpose of the Study:

• To introduce miRIAD, a web-service for analyzing intragenic miRNAs and their host genes.
• To provide a user-friendly platform for exploring genomic and functional annotations of intragenic miRNAs across five species.

Main Methods:

• Collected and processed public data on genomic and structural features.
• Classified miRNAs as intergenic or intragenic and genes as host or non-host.
• Integrated data on host gene function, miRNA binding sites, expression correlation, and protein-protein interactions.

Main Results:

• miRIAD offers classification of all miRNAs and protein-coding genes.
• Provides visualization of intragenic miRNA-host gene relationships, including expression data and binding sites.
• Includes protein-protein interaction data for host gene functional network analysis.

Conclusions:

• miRIAD facilitates exploration of intragenic miRNAs and their host genes.
• The web-service supports hypothesis generation and in-silico validation for researchers.
• A user-friendly environment is provided for minimal effort analysis.
