Introductory Analysis and Validation of CUT&RUN Sequencing Data

Area of Science:

• Molecular Biology
• Genomics
• Bioinformatics

Background:

• Cleavage Under Targets and Release помощью Nuclease (CUT&RUN) is a technique for detecting protein-DNA interactions.
• CUT&RUN offers advantages over ChIP-seq, including lower cell input and higher sensitivity.
• Analysis and validation of CUT&RUN sequencing data present a bottleneck for widespread adoption.

Purpose of the Study:

• To present a user-friendly, single-language bioinformatics pipeline for CUT&RUN sequencing analysis.
• To simplify the process of quality control, read alignment, and peak annotation for CUT&RUN data.
• To enable researchers with limited bioinformatics experience to analyze their CUT&RUN datasets.

Main Methods:

• Development of a step-by-step CUT&RUN analysis protocol using a single programming language.
• Inclusion of quality control checks for raw sequencing reads (depth, quality, biases).
• Guidance on read alignment to a reference genome and annotation of protein enrichment regions.

Main Results:

• A comprehensive protocol is provided for CUT&RUN data analysis, suitable for all experience levels.
• The pipeline facilitates critical quality checks to ensure data suitability for biological interpretation.
• Users can generate biological insights from their CUT&RUN datasets following the protocol.

Conclusions:

• The developed pipeline democratizes CUT&RUN data analysis, making it accessible to wet lab researchers.
• Simplifying bioinformatics analysis will accelerate the adoption and utility of the CUT&RUN technique.
• This protocol empowers researchers to independently analyze and interpret their protein-DNA interaction data.
