Programmed Cell Death Activates Latent Herpesviruses

WASHINGTON, DC – September 5, 2013 – Researchers have found that apoptosis, a natural process of programmed cell death, can reactivate latent herpesviruses in the dying cell. The results of their research, which could have broad clinical significance since many cancer chemotherapies cause apoptosis, was published ahead of print in the Journal of Virology.

Men-Only Hepatitis B Mutation Explains Higher Cancer Rates

WASHINGTON, DC – October 17, 2013 – A team of researchers has identified a novel mutation in the hepatitis B virus (HBV) in Korea that appears only in men and could help explain why HBV-infected men are roughly five times more likely than HBV-infected women to develop liver cancer. Although some women do progress to cirrhosis and liver cancer, the mutation is absent in HBV in women. The research is published ahead of print in the Journal of Clinical Microbiology .
