The National Institutes of Health (NIH), through the National Cancer Institute (NCI), is inviting applications for the Metastasis Research Network (MetNet): MetNet Research Projects, which will be funded via a cooperative agreement (U01). This initiative aims to advance the understanding of metastasis through systems-level approaches, encouraging research that addresses critical gaps in knowledge, particularly in areas such as early dissemination, microenvironment interactions, and cancer-specific processes. The program emphasizes collaboration among transdisciplinary teams, data sharing, and engagement with patient advocates, ultimately seeking to enhance therapeutic strategies and clinical practices related to metastasis. Funding is capped at $500,000 annually for projects lasting up to five years, with applications due by June 20, 2025.
