title: Oxidative stress decreases in the trophocytes and fat cells of worker honeybees during aging.
abstract: Trophocytes and fat cells of honeybees have been used for cellular senescence studies, but their oxidative stress and antioxidant enzyme activities with aging in workers is unknown. Here, we assayed reactive oxygen species and the activities of antioxidant enzymes in the trophocytes and fat cells of young and old workers. Young workers had higher reactive oxygen species levels, higher superoxide dismutase and thioredoxin reductase activities as well as lower catalase and glutathione peroxidase activities compared to old workers. Adding these results up, we propose that oxidative stress decreases with aging in the trophocytes and fat cells of workers.
