DNA methylation profiles of 30 tissues from a 112 year old woman

ABSTRACT: The main goal of the study was to measure the epigenetic age (also known as DNA methylation age) of these tissues. Toward this end, we used the epigenetic clock software described in Horvath S (n=2013) DNA methylation age of human tissues and cell types. Genome Biology.2013, 14:R115. DOI: 10.1186/10.1186/gb-2013-14-10-r115 PMID: 24138928 Human DNA methylation Beadchip v1.2 was used to obtain n=64 Illumina DNA methylation arrays from 30 tissues. For each of the following tissues, we obtained at least 2 replicates: adipose, adrenal gland, aorta, bone, bone-marrow, breast, buccal cells, cartilage, cerebellum, colon, diaphragm, esophagus , frontal cortex, kidney, heart, hippocampus, liver, lung, lymph node, midbrain, muscle, occipital cortex, pancreas, pericardium skin, spleen, stomach, temporal cortex, thyroid, whole blood.

Studies that elucidate why some human tissues age faster than others may shed light on how we age, and ultimately suggest what interventions may be possible. Here we utilize a recent biomarker of aging (referred to as epigenetic clock) to assess the epigenetic ages of up to 30 anatomic sites from supercentenarians (subjects who reached an age of 110 or older) and younger subjects. Using three novel and three published human DNA methylation data sets, we demonstrate that the cerebellum ages more  ...[more]
