DNA methylation profiles of human brain tissue samples


ABSTRACT: The main goal of the study was to measure the epigenetic age (also known as DNA methylation age) of human tissues and to relate it to chronological age. 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=260 Illumina DNA methylation array from the following human Brain regions: caudate nucleus (n=n=12), cingulate gyrus (n=n12), cerebellum (n=32), frontal cortex (n=41), hippocampus (n=25), midBrain (n=18), motor cortex (n=33), occipital cortex (n=33), parietal lobe (n=23), sensory cortex (n=12), temporal cortex (n=29), visual cortex (n=11).

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]
