PML and hepatocellular carcinoma: Survival rates for PML+/+HBsAgtg/0 mice with very late-onset angiogenic HCC responding to As2O3 were lower than for PML−/−HBsAgtg/0 mice with very early-onset adipose-like HCC resistant to As2O3, suggesting that HCC without PML might have a relatively indolent, low-grade character.
