Research Abstract |
In this study, we established a transgenic (β5t-Tg) mouse model with decreased proteasomal chymotrypsin-like activity. β5t-Tg mice exhibited a shortened lifespan and age-related phenotypes. When β5t-Tg mice were fed a high-fat diet, they developed more pronounced obesity and hepatic steatosis than wild-type mice. It has been known that proteasome plays an important role in the immune system, and β5t-Tg mice show abnormal T cell maturation. Our results demonstrate that decreased proteasomal chymotrypsin-like activity affects longevity and aggravates age-related metabolic disorders such as obesity and hepatic steatosis, and may correlate to the pathogenesis of immune-related disorders
