📝 英文原版摘要

Proceedings of the National Academy of Sciences, Volume 123, Issue 11, March 2026. <br />SignificanceWhile DNA methylation is the standard for epigenetic aging, histone modifications regulate the dynamic plasticity of the genome yet remain an untapped resource for age prediction. We developed robust histone-based clocks that parallel ...
