LncRNAway: a web-based sgRNA design tool for precise and effective suppression of long noncoding RNAs

Area of Science:

• Molecular Biology
• Genomics
• Bioinformatics

Background:

• Thousands of long noncoding RNAs (lncRNAs) are identified, but few are functionally characterized.
• Genomic knockout is standard for gene function studies, but lncRNA locus complexity, especially natural antisense lncRNAs (NAT-lncRNAs), poses challenges.
• Current knockout methods risk disrupting adjacent protein-coding genes and small RNAs, complicating phenotype interpretation.

Purpose of the Study:

• To develop a user-friendly web tool, LncRNAway, for designing specific single-guide RNAs (sgRNAs) for lncRNA knockout.
• To facilitate precise lncRNA functional studies by minimizing off-target effects on neighboring genes.

Main Methods:

• LncRNAway utilizes the BESST (branchpoint to 3' splicing site targeting) method for sgRNA design.
• The tool integrates primer design for genotyping and quantitative PCR (qPCR).

Main Results:

• LncRNAway provides specific and effective sgRNA design for lncRNA knockout.
• The integrated primer design streamlines experimental workflows for lncRNA function studies.

Conclusions:

• LncRNAway addresses the challenge of ambiguous lncRNA function interpretation caused by off-target effects.
• This tool enhances the efficiency and accuracy of lncRNA functional investigations.
