Horvath clock assessment
WebSep 25, 2024 · The interesting aspect of Hannum's clock is that it facilitates the measurement of all-cause mortality in an individual. Unlike Horvath's clock which may facilitate the assessment of DNA methylation changes through the assessment of tissues and cells, Hannum's clock applies primarily to blood in assessing molecular age. WebAim: To examine the relationships between two epigenetic clocks, aging and exceptional longevity. Materials & methods: Participants were from three adult cohorts with blood DNA methylation data (Illumina 450 K, n = 275, 34-103 years). Epigenetic age (DNAmage) and age acceleration measures were calculated using the Hannum and Horvath epigenetic clocks.

The clock is defined as an age estimation method based on 353 epigenetic markers on the DNA. The 353 markers measure DNA methylation of CpG dinucleotides. Estimated age ("predicted age" in mathematical usage), also referred to as DNA methylation age, has the following properties: first, it is close to zero for embryonic and induced pluripotent stem cells; second, it correlates with cell passage number; third, it gives rise to a highly heritable measure of age acceleration; and, fo… WebThis has become known as the “Horvath Test”.
