Abstract
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. (2021).1.
