WebApr 7, 2024 · We calculated epigenetic clocks, including the Horvath, 28 Hannum, 10 PhenoAge, 11 and GrimAge 12 clocks, using the online DNA Methylation Age Calculator developed by the Horvath laboratory. 29 The residuals of epigenetic age acceleration were obtained by regressing the corresponding DNAm age on chronological age. WebDNA is the hardware, genetics is the operating system, and DNA methylation and other epigenetic factors are the software that programs the genome. A paradigm shift in the search for biological age markers occurred with the discovery of the “epigenetic clock” by Horvath, which is based on the measurement of DNA methylation status at 500 ...
