Technical BHC and the alpha, beta, gamma and delta isomers of BHC are carcinogenic for the liver of mice and rats. Mice given the isomers of BHC developed carcinomas and hyperplastic nodules of the liver as early as 24 weeks. Several strains of mice (dd, ICR-JLC, CL1, DDY, IRC, DBA/Z, C3H/HEN, C57BL/6 were susceptible. Male mice were more susceptible to hepatic carcinogenesis than female mice and they appeared to be more susceptible to alpha-BHC. The incidence of neoplasms of the liver was increased when beta-, gamma-, or delta-BHC were each given together with alpha-BHC. PCB-5 promoted the induction of hepatic neoplasms when administered with beta-BHC. Technical BHC and its isomers are carcinogenic for the liver of male and female Wistar rats. Beta-BHC is carcinogenic for the liver of Osborne-Mendel male rats. Osborne-Mendel rats receiving delta-BHC developed cirrhosis of the liver, portal vein thrombosis, and focal necrosis of the skeletal muscle. Male rats ingesting technical BHC or the beta or delta isomers also had atrophic testes.

The liver plays a central role in toxicology. It is the primary organ of detoxification and elimination by metabolism of many chemicals. Many workplace chemicals can affect the liver in animals; fewer have been proved to do so in humans. The diverse hepatic effects observed in humans from occupational exposure to chemicals range from fatty infiltration, acute hepatitis and cholestasis to cirrhosis and angiosarcoma. Three important workplace chemicals, prototypes for the toxicities of many others, are carbon tetrachloride, vinyl chloride and the polychlorinated biphenyls (PCB's). These three are described in some detail to highlight principles of occupational toxicology. Most of the hepatic effects produced by chemicals in the workplace have clinical, laboratory and morphological features common to many other forms of liver disease. Therefore, only an astute physician who takes an occupational history will recognize the association between a patient's workplace and liver disease.

Hepatitis C virus (HCV) infection frequently leads to chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. There is no effective therapy or vaccine available to HCV-infected patients other than interferon-ribavarin combination, which is effective in a relatively small percentage of infected patients. Our previous results have shown that a synthetic peptide (LAP) corresponding to the N-terminal 18 amino acids of the Lupus autoantigen (La) was a potent inhibitor of HCV IRES-mediated translation. We demonstrate here that LAP efficiently blocks HCV replication of infectious JFH1 virus in cell culture. Our data suggest that LAP forms complexes with IRES-transacting factors (ITAFs) PTB and PCBP2. LAP-mediated inhibition of HCV IRES-mediated translation in vitro could be fully rescued by recombinant PCB and PCBP2. Also transient expression of PTB / PCBP2 combination significantly restores HCV replication in LAP-inhibited cultures. These results suggest that ITAFs could be potential targets to block HCV replication.
