Protocol for generation of humanized HCC mouse model and cancer-driver mutations using CRISPR-Cas9.

ABSTRACT

We detail procedures for generating a humanized mouse model of hepatocellular carcinoma (HCC) recapitulating genetic mutations associated with metabolic liver diseases (MLD). We humanized liver parenchymal, non-parenchymal, and hematopoietic cells. We employed CRISPR-Cas9-based ARID1A knockout and constitutively active CTNNB1 knockin combined with an alcohol Western diet to generate cancer-driver mutations commonly found in MLD-HCC patients. This HCC model facilitates the study of tumor-promoting gene-environment interactions. For complete details on the use and execution of this protocol, please refer to Yeh et al.1.
