Project Title:Unchecked oxidative stress is an insurmountable barrier for tumour cells that disseminate to skeletal muscle
Project Summary:Skeletal muscle has been recognized as an inhospitable site for disseminated tumour cells (DTCs) for decades, yet its antimetastatic nature has eluded a thorough mechanistic description. Here, we show that DTCs traffic to and persist within skeletal muscle, raising the question as to how this tissue suppresses colonization. We employed mouse and organotypic culture models along with metabolomic profiling and ultimately find that oxidative stress is a principal suppressor of DTC proliferation in skeletal muscle. DTCs bypassed this oxidative constraint upon colonization of more fertile sites, but were unable to in muscle. Functional studies demonstrated that disrupting redox homeostasis via chemogenetic induction of reactive oxygen species slowed proliferation in lung. Conversely, enhancing antioxidant potential of tumour cells via ectopic expression of catalase allowed robust colonization of skeletal muscle. These findings reveal a profound metabolic bottleneck imposed on DTCs and sustained by skeletal muscle. Understanding this biology could reveal novel DTC vulnerabilities.
