Ítem Centenarian clocks: epigenetic clocks for validating claims of exceptional longevity(SPRINGER LINK, vol. 45, 2023) Dec, Eric; Clement, James; Cheng, Kaiyang; Church, George M.; Fossel, Michael B.; Rehkopf, David H.; Rosero Bixby, Luis; Kobor, Michael S.; Lin, David TS.; Lu, Ake T.; Fei, Zhe; Guo, Wei; Chew, Yap Ching; Yang, Xiaojing; Dwi Putra, Sulistyo E.; Reiner, Alex P.; Correa, Adolfo; Vilalta, Adrian; Pirazzini, Chiara; Passarino, Giuseppe; Monti, Daniela; Arosio, Beatrice; Garagnani, Paolo; Franceschi, Claudio; Horvath, SteveClaims surrounding exceptional longevity are sometimes disputed or dismissed for lack of credible evidence. Here, we present three DNA methylation-based age estimators (epigenetic clocks) for verifying age claims of centenarians. The three centenarian clocks were developed based on n = 7039 blood and saliva samples from individuals older than 40, including n = 184 samples from centenarians, 122 samples from semi-supercentenarians (aged 105 +), and 25 samples from supercentenarians (aged 110 +). The oldest individual was 115 years old. Our most accurate centenarian clock resulted from applying a neural network model to a training set composed of individuals older than 40. An epigenome- wide association study of age in different age groups revealed that age effects in young individuals (age < 40) are correlated (r = 0.55) with age effects in old individuals (age > 90). We present a chromatin state analysis of age effects in centenarians. The centenarian clocks are expected to be useful for validating claims surrounding exceptional old age.
