Queen’s scent rules the nest: a single chemical governs reproductive suppression in naked mole-rats

Researchers identify isopropyl myristate as a queen-derived chemical cue in naked mole-rats that modulates social hierarchy by suppressing reproduction in non-breeders, via olfactory detection and hormonal changes; the compound is enriched in queens and can prevent queen replacement, with related signals found in Fukomys species, highlighting a chemical mechanism linking mammalian eusociality to insect models.

Naked mole-rats reveal clues to aging: longevity, cancer resistance, and hypoxia survival

Naked mole-rats live 30–40 years, show negligible senescence and rare cancer, and tolerate low-oxygen environments, partly due to unusually large hyaluronan that slows cell division and helps regulate growth. They also metabolically adapt to hypoxia, enabling survival in oxygen-poor burrows. These traits provide concrete, testable aging mechanisms that researchers hope may translate to humans; in mice, inserting the mole-rat hyaluronan gene yielded about a 4.4% median lifespan increase and fewer tumors, but the human relevance remains uncertain.

Scientists Discover Promising Gene Transfer Technique for Extending Lifespan and Preventing Cancer

Scientists at the University of Rochester have successfully transferred a longevity gene from naked mole rats to mice, resulting in improved health and an approximate 4.4 percent increase in the median lifespan for the mice. Naked mole rats, known for their resistance to age-related diseases, produce high molecular weight hyaluronic acid (HMW-HA), which when introduced to mice, demonstrated potential anti-aging benefits. This breakthrough paves the way for potential advancements in extending human lifespan and improving health by understanding the unique mechanisms of aging and disease resistance in naked mole rats.
