Trophocytes and oenocytes of honeybees are used in studies of cellular senescence, but their cellular energy metabolism with age is poorly understood. In this study, the molecules involved in cellular energy metabolism were evaluated in the trophocytes and oenocytes of young and old worker bees. The results revealed that (i) β-oxidation and protein synthesis decreased with age, (ii) fat and glycogen...
The trophocytes and fat cells of honeybees (Apis mellifera) have been used in cellular senescence studies, but the changes of cellular degradation activity with aging in workers are unknown. In this study, cellular degradation activity was evaluated in the trophocytes and fat cells of young and old workers reared in a field hive. The results showed the following: (1) 20S proteosome activity decreased...
Trophocytes and fat cells in honeybees (Apis mellifera) have served as targets for cellular senescence studies, but mitochondrial energy utilization with advancing age in workers is unknown. In this study, mitochondrial energy utilization was evaluated in the trophocytes and fat cells of young and old workers reared in a field hive. The results showed that (1) mitochondrial density increased with...
