increased hepatocellular carcinoma incidence ( J:153945 )
• highly aggressive hepatocellular carcinomas (HCCs)
• HCCs in 3 out of 12 mice by 15 months of age
• no mice (n = 6) have visible tumors among 7-month-old asymptomatic animals
• Western blotting, PCR analysis of HCCs reveals the absence of wild-type proteins and DNA of both alleles
