DNA methylation clocks tick in naked mole rats but queens age more slowly than nonbreeders.

There was nominally significant evidence of slower aging rates in skin samples from four queens, the oldest of which showed substantially younger epigenetic age as predicted by the skin clock ( Fig. 6 ) ( P = 0.038 for the pan-tissue clock, Fig. 6d ; P = 0.061 for the human–NMR clock, Fig. 3e ; P = 0.0025 for the skin clock).
