Whole blood DNA methylation samples from HIV positive men [2012 study]

ABSTRACT: Genome wide DNA methylation profiles of whole blood from HIV positive men. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 480,000 CpGs. Dataset included 24 subjects from the USA. This data set was used as validation set for studying the effect of HIV viral load on host DNA methylation levels. Bisulphite converted DNA from the 24 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip. Subjects had different levels of HIV viral load. This dataset reports DNA methylation data set on 24 subjects that were generated in 2012 (while the other data set of 120 subjects reports DNA meth data generated in 2013). Details on what each sample characteristics and their values represent are provided in the 'characteristics_readme.txt' file.

HIV-1 Infection Accelerates Age According to the Epigenetic Clock.

Horvath Steve S Levine Andrew J AJ

The Journal of infectious diseases 20150512 10

<h4>Background</h4>Infection with human immunodeficiency virus type 1 (HIV) is associated with clinical symptoms of accelerated aging, as evidenced by the increased incidence and diversity of age-related illnesses at relatively young ages and supporting findings of organ and cellular pathologic analyses. But it has been difficult to detect an accelerated aging effect at a molecular level.<h4>Methods</h4>Here, we used an epigenetic biomarker of aging based on host DNA methylation levels to study ...[more]

Whole blood DNA methylation samples from HIV positive men [2013 study]

Project description:Genome wide DNA methylation profiles of whole blood from HIV positive men. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 480,000 CpGs. Dataset included 120 subjects from the USA but because of missing clinical characteristics only 109 subjects were used in the scientific publication. The study analyzed the effect of HIV viral load on host DNA methylation levels. Bisulphite converted DNA from the 120 HIV positive men were hybridised to the Illumina Infinium 450k Human Methylation Beadchip. Subjects had different levels of HIV viral load. This dataset reports DNA methylation data set on 120 subjects that were generated in 2013 (while the other data set of 24 subjects reports DNA methylation data generated in 2012).

Cerebellum Illumina Inf 450 DNA methylation samples from HIV+ and HIV- human subjects

Project description:Genome wide DNA methylation profiles of cerebellum from HIV positive and HIV negative human subjects. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 486,000 CpGs. Dataset included 20 subjects from the USA. The epigenetic clock software (Horvath 2013) was used to measure epigenetic age acceleration effects and to relate them to HIV status. Bisulphite converted DNA from the 20 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip. 8 HIV+ subjects were compared to 12 HIV- subjects.

Frontal lobe (brain) Illumina Inf 450 DNA methylation samples from HIV+ and HIV- human subjects

Project description:Genome wide DNA methylation profiles of Frontal Lobe from HIV positive and HIV negative human subjects. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 486,000 CpGs. Dataset included 33 subjects from the USA. The epigenetic clock software (Horvath 2013) was used to measure epigenetic age acceleration effects and to relate them to HIV status. Bisulphite converted DNA from the 33 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip. 8 HIV+ subjects were compared to 25 HIV- subjects.

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).
