[ad_1] The largest of the present challenges facing the use of epigenetic clocks to measure biological age is that there is no established causal connection between what the clock measures, meaning the methylation status of specific CpG sites on the genome, and specific aspects of the burden of age-related damage and dysfunction; e.g. which … Read more
[ad_1] In the past year or two, a great deal of effort on the part of leading researchers has gone into trying to standardize the use of a single epigenetic clock based on DNA methylation status of CpG sites on the genome. Suitable candidate universal mammalian clocks now exist. There are good reasons for … Read more
[ad_1] Recent years have made it clear that any sufficiently large set of data derived from biochemistry or physiology can be fed into a machine learning process to develop an weighted combination of measures that reflects biological age. These aging clocks have been derived from many forms of omics data, from frequently measured blood … Read more
