September 6, 2011 u vol. 108 u no. 36 u 14707–15010 Cover image: Pictured are gastric epithelial cells infected with the gut bacteria, Helicobacter pylori, which are associated with an increased risk of gastric cancers. Isabella M. Toller et al. found that H. pylori infection damages the genome of host cells, causing breaks in both complementary strands of DNA. The damage triggered DNA repair responses, but pro- longed infection resulted in unrepaired DNA breaks and harmed host cell viability. The findings suggest a possible mechanism for the bacteria’s carcinogenic properties. See the article by Toller et al. on pages 14944–14949.
