Gut bacteria "talk" to horse's cells to improve their athletic performance

A horse's gut bacteria communicate with the mitochondria, the components in the cells that generate and regulate energy, finds a new study. It reveals the chemical signals, in the form of metabolites produced by the bacteria breaking down food for growth and energy, have the effect of "turning on" specific genes that help the horse to extend its energy output. This study paves the way for dietary interventions that could enhance equine performance.
