Naked mole-rats (NMRs, Heterocephalus glaber) are the longest-lived rodents with a maximum life span exceeding 37 years. They exhibit a delayed aging phenotype and resistance to age-related functional decline/diseases. Specifically, they do not display increased mortality with age, maintain several physiological functions until nearly the end of their lifetime, and rarely develop cancer and Alzheimer's disease. NMRs live in a hypoxic environment in underground colonies in East Africa and are highly tolerant of hypoxia. These unique characteristics of NMRs have attracted considerable interest from zoological and biomedical researchers. This review summarizes previous studies of the ecology, hypoxia tolerance, longevity/delayed aging, and cancer resistance of NMRs and discusses possible mechanisms contributing to their healthy aging. In addition, we discuss current issues and future perspectives to fully elucidate the mechanisms underlying delayed aging and resistance to age-related diseases in NMRs.
期刊介绍：
The Annual Review of Animal Biosciences is primarily dedicated to the fields of biotechnology, genetics, genomics, and breeding, with a special focus on veterinary medicine. This includes veterinary pathobiology, infectious diseases and vaccine development, and conservation and zoo biology. The publication aims to address the needs of scientists studying both wild and domesticated animal species, veterinarians, conservation biologists, and geneticists.
