In vivo analysis of FBXO45-mediated fibrosis and liver tumorigenesis in a chemically induced mouse model of hepatocellular carcinoma

Summary: FBXO45, an E3 ubiquitin ligase highly expressed in liver tumors, is positively correlated with poor survival of hepatocellular carcinogenesis (HCC) patients, but whether FBXO45 drives HCC tumorigenesis remains largely unclear. Here, we describe a protocol that shortens the observation period for HCC tumorigenesis to assess the effects of FBXO45 in a DEN/CCl4-induced HCC mouse model. We describe steps for chemical induction of HCC in FBXO45-overexpressing mice, followed by tissue collection and pathology assessment via quantitative real-time PCR, histology, and immunohistochemistry.For complete details on the use and execution of this protocol, please refer to Lin et al.
