In a new study, the John Denu lab has learned that the fatty acids butyrate and propionate also activate p300, a crucial human enzyme that promotes the unspooling of DNA. This unwound DNA allows more genes to become active and expressed, which ultimately affects human health.

While studying the three-member model microbial community, nicknamed The Hitchhikers of the Rhizosphere (THOR), researchers from professor of plant pathology and director of the Wisconsin Institute for Discovery Jo Handelsman and professor of biomedical engineering and Discovery Fellow David Beebe’s labs noticed cells moving in unexpected, unique ways under the microscope.
