Alogliptin is a commonly prescribed drug treating patients with type 2 diabetes. Here, we show that long‐term intervention with alogliptin (0.03% w/w in diet) improves survival and health of mice on a high‐fat diet. Alogliptin intervention takes beneficial effects associated with longevity, including increased insulin sensitivity, attenuated functionality decline, decreased organ pathology, preserved mitochondrial function, and reduced oxidative stress. Autophagy activation is proposed as an underlying mechanism of these beneficial effects. We conclude that alogliptin intervention could be considered as a potential strategy for extending lifespan and healthspan in obesity and overweight.
The number of overweight and obese individuals worldwide has increased dramatically over the past 30 years, leading to an explosion of obesity‐related health problems associated with increased morbidity and mortality. Patients with obesity exhibit many manifestations of accelerated aging, such as cardiovascular disease, diabetes, hypertension, dyslipidemia, nonalcoholic fatty liver disease and inflammatory disorders, all of which reduce lifespan. For these reasons, ways to improve the obesity‐related health problems for extending longevity are actively pursued.
Our present data for the first time suggested that alogliptin intervention extends longevity and improves health of mice with excess caloric intake. These beneficial effects are mainly related to increased insulin sensitivity, attenuated function decline, decreased organ pathology, inhibited inflammation, preserved mitochondrial function, and reduced oxidative stress. Autophagy activation may be involved in these beneficial effects. Thus, alogliptin intervention is considered as a potential strategy for extending lifespan and healthspan in obesity and overweight.
