iSmaRT: a toolkit for a comprehensive analysis of small RNA-Seq data

Area of Science:

• Genomics
• Bioinformatics
• Molecular Biology

Background:

• Small non-coding RNAs (sncRNAs) play crucial biological roles.
• Existing tools primarily focus on microRNAs (miRNAs), with limited options for PIWI-interacting RNAs (piRNAs).
• There is a growing need for comprehensive analysis tools for diverse sncRNA classes.

Purpose of the Study:

• To introduce iSmaRT, an automated pipeline for analyzing small RNA sequencing (smallRNA-Seq) data.
• To provide a user-friendly interface for comprehensive sncRNA analysis, including novel piRNA discovery and target prediction.
• To demonstrate the pipeline's performance using a relevant biological dataset.

Main Methods:

• Development of an automated bioinformatics pipeline named iSmaRT.
• Integration of various bioinformatics tools and custom algorithms.
• Implementation of a Graphical User Interface (GUI) for accessibility.
• Inclusion of specific modules for PIWI-interacting RNA (piRNA) analysis.

Main Results:

• iSmaRT enables comprehensive analysis of both microRNAs (miRNAs) and PIWI-interacting RNAs (piRNAs).
• The pipeline facilitates the prediction of novel piRNAs and their RNA targets.
• Demonstrated rapid and user-friendly analysis of a smallRNA-Seq dataset from Huntington's Disease patient brain samples.
• Successful illustration of iSmaRT's capability in analyzing diverse sncRNA classes.

Conclusions:

• iSmaRT addresses the limitations in analyzing novel sncRNA classes, particularly piRNAs.
• The pipeline offers a rapid, user-friendly, and comprehensive solution for smallRNA-Seq data analysis.
• iSmaRT enhances the study of biological roles for various sncRNAs, including piRNAs.
