Chemoprevention of hepatocellular carcinoma using N-acetylgalactosamine-conjugated siRNAs.

ABSTRACT: The ability to prevent hepatocellular carcinoma (HCC) in patients with chronic liver disease remains an unmet clinical need. We performed a head-to-head comparison of N-acetylgalactosamine (GalNAc)-conjugated small interfering RNA (siRNA)-mediated inhibition of five genes (CDK1, PD-L1, CTNNB1, SMYD3, ANLN) to prevent cancer in four distinct autochthonous HCC mouse models. siRNA targeting Cdk1 and Anln (siCdk1 and siAnln, respectively) increased overall survival in the CTNNB1/MYC hydrodynamic transfection (HDT) model, in which HCC formation is driven by oncogenes. Both long-term and transient dosing of siCtnnb1 or siAnln prevented cancer development in the NRASG12V/shp53-driven HDT model. siCdk1 and siAnln prevented cancer in a diethylnitrosamine/phenobarbital model, in which tumor formatio
