**National Resource for Network Biology (NRNB)** is a pioneering initiative aimed at enhancing the understanding of biological networks through an array of advanced analytic tools, visualizations, and databases. Focused on the intersections of gene, protein, and drug interactions, NRNB empowers biomedical researchers to navigate the complexities of cellular communications and social networks that are vital to understanding health and disease mechanisms.

Leveraging the established Cytoscape Cyberinfrastructure, NRNB supports a vibrant community of researchers through comprehensive resources, including tutorials, workshops, and continuous help desk assistance. The organization is committed to developing open-source software for network-based visualization and analysis, facilitating biomedical discoveries across various scientific domains.

With a renewed five-year funding commitment from NIGMS until 2025, NRNB focuses its efforts on major research themes such as Differential Networks and Multi-scale Network Representations. Recent advancements include innovative projects like NeXO, which constructs cellular hierarchies from extensive interaction data, and the Cancer Biology Portal, a powerful resource for analyzing tumor mutations. Through collaboration and training, NRNB continues to drive progress in network biology research.
