Project description:Genome wide DNA methylation profiling of hypertensive, pre-hypertensive, and healthy control samples. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles. Samples included 44 hypertensive samples, 44 pre-hypertensive samples, and 44 healthy controls.

DNA methylation levels of various brain regions from HIV+ and HIV- subjects

Project description:Genome wide DNA methylation profiles of various human brain regions (cerebellum, occipital lobe, etc). The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 480,000 CpGs. The dataset includes 130 samples. Multiple brain regions were assessed per subject. The goal was to evaluate the effect of HIV infection on DNA methylation levels. Genome wide DNA methylation profiles of various brain regions from HIV positive and negative subjects. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 480,000 CpGs. Dataset included 130 samples: 99 samples from HIV+ subjects and 31 samples from HIV- subjects. The Illumina Infinium450 platform was applied to various brain regions from HIV+ and HIV- subjects. We evaluated 130 brain samples from 84 different subjects. Specifically, we considered cerebellum (20 HIV+ samples and 4 controls), frontal lobe (2 cases, 4 controls), hippocampus (4 controls), medial frontal cortex (18 cases), occipital cortex (59 cases, 13 controls), temporal cortex (4 controls). In total, there were 99 samples from HIV+ subjects and 31 samples from HIV- controls of similar ages. The subjects were recruited from the National Neurological AIDS Bank study or Multicenter AIDS Cohort study in Los Angeles. Informed consent and all study procedures were approved by the UCLA Medical IRB. DNAm data from HIV+ cases and HIV- controls were generated at the same time and randomized across plates and chips. HIV viral load information was available for blood (measured at the last blood draw) and for cerebrospinal fluid (CSF).

Epigenetics of Yakutia and Central Russia regions

Project description:Lobachevsky University DNAm dataset. Whole blood DNA Methylation (EPIC) profiles from healthy samples from two regions: central Russia (131 samples) and Yakutia (114 samples) obtained in the Laboratory of System Medicine for Healthy Aging, Lobachevsky State University of Nizhny Novgorod, Russia Dataset contains DNAm data from 245 healthy control samples from two regions: central Russia (131) and Yakutia (114). The following characteristics are available for all samples: sex, age, region. Healthy participants in the central Russia region were recruited in 2019–2022. Yakutian participants we recruited in 2022. All measurements were performed at the Laboratory of System Medicine for Healthy Aging, Lobachevsky State University of Nizhny Novgorod, Russia.

DNA Methylation profiles of subjects in the Healthy Brain Initiative study.

Project description:The Healthy Brain Initiative (HBI) is a longitudinal study focused on older adults in South Florida, with the goal of advancing dementia prevention and promoting brain health. We generated DNA methylation profiles for 88 HBI participants aged over 65. The Illumina MethylationEPIC v2.0 Beadchip was used to obtain DNA methylation profiles across approximately 935k CpGs from human blood samples.
