摘要：

Metastasis formation is the leading cause of death in cancer patients. Yet, the molecular mechanisms responsible for the aggressiveness of metastases remain largely unknown. We used experimental metastasis mouse models and samples from patients with breast cancer to study metastases aggressiveness. We discovered that the aggressiveness of cancer cells in lung metastases was driven by an alternative translational program that was regulated by metabolite signaling. Strikingly, the identified molecular mechanism could be disrupted by repurposing a clinical approved inhibitor, which resulted in reduced metastasis formation in mouse models. Thus, this research highlights that dissecting and targeting cancer cell aggressiveness may provide therapeutic options against metastasis formation.
