Metastasis development in a novel mouse model of advanced liver cancer

Introduction: Liver cancer is one of the leading causes of cancer related mortality worldwide. It is often diagnosed in advanced stages when treatment options remain limited. Novel diagnostic markers and therapies are therefore urgently needed. The absence of reliable mouse models has been a major limitation in the study of advanced, metastatic liver cancer in the past. Here, we present a novel genetically engineered mouse model of primary liver cancer. In this model, activation of oncogenic Kras together with functional inactivation of the tumor suppressor proteins RB and p53 mimics molecular events that occur…
