Prolonged spaceflight has a limited effect on oxidative stress in the heart. All genes associated with the oxidative stress pathway were uploaded for subset analyses in David Gene Ontogeny. Ninety four percent of transcripts that affect oxidative stress were not significantly changed by spaceflight after 30 days. Six percent of the total number of transcripts analyzed were significantly impacted by spaceflight (p ≤ 0.0005).
