lncRNAMap: a map of putative regulatory functions in the long non-coding transcriptome

Area of Science:

• Genomics
• Molecular Biology
• Bioinformatics

Background:

• Long non-coding RNAs (lncRNAs) play crucial roles in gene regulation, including chromatin remodeling and transcriptional control.
• The functions of many lncRNAs remain uncharacterized, necessitating tools for their study.
• Understanding lncRNA regulatory mechanisms is vital for advancing molecular biology.

Purpose of the Study:

• To develop a user-friendly platform for investigating the putative regulatory functions of human lncRNAs.
• To explore lncRNA roles in encoding small interfering RNAs (siRNAs) and acting as microRNA (miRNA) decoys.
• To facilitate research into lncRNA-mediated gene regulation.

Main Methods:

• Integrated publicly available deep sequencing data to identify lncRNA-derived siRNAs and their target interactions.
• Analyzed lncRNAs acting as miRNA decoys, regulating protein-coding genes.
• Surveyed neighboring gene expression profiles relative to lncRNA genomic locations to infer regulatory relationships.

Main Results:

• Developed lncRNAMap, a comprehensive database detailing lncRNA regulatory mechanisms.
• Identified interactions between lncRNAs, siRNAs, and protein-coding genes.
• Provided expression profiles correlating lncRNAs with their neighboring genes.

Conclusions:

• lncRNAMap is a powerful, user-friendly platform for studying human lncRNA functions.
• The database supports investigations into lncRNAs producing siRNAs and acting as miRNA decoys.
• lncRNAMap is freely accessible online, promoting research in lncRNA biology.
