RiboCAT: a new capillary electrophoresis data analysis tool for nucleic acid probing

Area of Science:

• Molecular Biology
• Biochemistry
• Bioinformatics

Background:

• Understanding structured RNAs requires chemical and enzymatic probing for RNA secondary structure and RNA/protein interactions.
• Current capillary electrophoresis data analysis software is labor-intensive, requiring manual intervention and limiting user modification.

Purpose of the Study:

• To develop user-friendly software to reduce manual intervention in capillary electrophoresis data analysis for RNA structure studies.
• To shorten the time required for analyzing RNA secondary structure and RNA/protein interaction data.

Main Methods:

• Development of RiboCAT (Ribonucleic acid capillary-electrophoresis analysis tool), a Microsoft Excel-based platform.
• Implementation of intercapillary signal alignment using internal size standards and a peak-sharpening algorithm.
• Creation of RiboDOG (RiboCAT data output generator) for comparing multiple datasets and identifying analysis inconsistencies.

Main Results:

• RiboCAT significantly reduces manual intervention and analysis time for capillary electrophoresis data.
• The software features an Excel platform, signal alignment, peak sharpening, and an open architecture for user modification.
• RiboDOG facilitates multi-dataset comparison, improving accuracy and highlighting potential errors.

Conclusions:

• RiboCAT and RiboDOG provide efficient and user-friendly solutions for RNA structure and interaction analysis.
• The tools enable accurate secondary structure determination, as demonstrated by HIV-1 5'UTR analysis using SHAPE.
• These advancements accelerate the study of structured RNA functions through improved data analysis.
