Another HTVI-based study modeling the consequences of RAS-driven carcinogenesis was later described by Zhang et al. Here, hydrodynamic injection of NRAS (G12V) and a constitutively active form of AKT (myrAKT) also yielded HCC and iCCA in mice 3 to 4 weeks after injection [14]. This evidence concerns the gene NRAS and hepatocellular carcinoma.
