TL;DR
MulNet is a new framework that builds detailed gene interaction networks from RNA-seq data, revealing key regulators and communication in cancer.
Contribution
MulNet introduces a scalable multilayer network framework to integrate diverse molecular interactions and identify biologically relevant gene modules and regulators.
Findings
MulNet outperformed existing methods in identifying gene modules across cancer datasets.
MulNet identified miR-8485 as a new therapeutic target in colon cancer and its downstream pathways.
Analysis of single-cell data revealed communication networks between fibroblasts and cancer cells in head and neck cancer.
Abstract
Gene expression involves complex interactions between DNA, RNA, proteins, and small molecules. However, most existing molecular networks are built on limited interaction types, resulting in a fragmented understanding of gene regulation. Here, we present MulNet, a framework that organizes diverse molecular interactions underlying gene expression data into a scalable multilayer network. Additionally, MulNet can accurately identify gene modules and key regulators within this network. When applied across diverse cancer datasets, MulNet outperformed state-of-the-art methods in identifying biologically relevant modules. MulNet analysis of RNA-seq data from colon cancer revealed numerous well-established cancer regulators and a promising new therapeutic target, miR-8485, along with several downstream pathways it governs to inhibit tumor growth. MulNet analysis of single-cell RNA-seq data from…
