RNA structure analysis of viruses using SHAPE

Area of Science:

• Molecular Biology
• Biochemistry
• Virology

Background:

• Investigating RNA secondary and tertiary structures is crucial for understanding gene regulation and viral replication.
• Traditional methods for RNA structure probing often lack the resolution and throughput required for complex RNA molecules.
• Selective 2' hydroxyl acylation analyzed by primer extension (SHAPE) has emerged as a powerful technique for RNA structure elucidation.

Purpose of the Study:

• To present optimized protocols for Selective 2' hydroxyl acylation analyzed by primer extension (SHAPE).
• To adapt and validate these SHAPE protocols for the analysis of poliovirus RNA.
• To provide a comprehensive workflow from RNA extraction to data processing for SHAPE experiments.

Main Methods:

• Nondenaturing RNA extraction from viral samples.
• Chemical modification of RNA using SHAPE reagents.
• Primer extension assays to detect modification sites.
• Data analysis using the ShapeFinder software.

Main Results:

• Established robust protocols for SHAPE experiments on poliovirus RNA.
• Demonstrated improved resolution and throughput for RNA structure analysis.
• Successfully processed and analyzed SHAPE data using ShapeFinder.

Conclusions:

• The presented SHAPE protocols are effective for high-resolution RNA structure analysis of poliovirus.
• These optimized methods enhance the capability to study complex RNA structures in a high-throughput manner.
• The workflow facilitates a deeper understanding of RNA structure-function relationships in viral systems.
