MMiRNA-Viewer², a bioinformatics tool for visualizing functional annotation for MiRNA and MRNA pairs in a network

Area of Science:

• Bioinformatics
• Genomics
• Cancer Research

Background:

• MicroRNA-mRNA interactions are complex and not fully understood in cancer.
• Existing methods struggle to analyze paired tumor and normal samples simultaneously.
• This complexity hinders the clinical application of miRNA-mRNA interaction data.

Purpose of the Study:

• To develop an innovative bioinformatics tool for visualizing functional consequences of miRNA-mRNA pairs.
• To enable simultaneous analysis of tumor and normal samples for miRNA-mRNA interactions.
• To aid in identifying cancer-associated genes and regulatory networks.

Main Methods:

• Development of MMiRNA-Viewer², a web server for visualizing miRNA-mRNA networks.
• Integration of gene annotation, pathway information, and cancer association data.
• Utilizing next-generation sequencing data for concurrent analysis of tumor and normal samples.

Main Results:

• MMiRNA-Viewer² visualizes miRNA-mRNA regulation networks with functional annotations.
• The tool integrates gene annotation, signaling pathways, and cancer associations.
• It identifies pivotal miRNAs/mRNAs contributing to cancer complexity and allows comparison with other tools.

Conclusions:

• MMiRNA-Viewer² is a multitasking platform for identifying significant miRNA-mRNA interaction clusters.
• It facilitates retrieval of functional and cancer-associated information from paired samples.
• The tool is broadly applicable to various diseases and cancers, offering advantages over existing methods.
