Project description:Human DNA methylation Beadchip v1.2 was used to profile buffy coat samples. The main goal of the study was to relate DNA methylation data to Huntington disease status (control, pre-manifest disease, manifest motor disease).
Project description:Cord blood DNA methylation is associated with numerous health outcomes and environmental exposures. Whole cord blood DNA reflects all nucleated blood cell types, while centrifuging whole blood separates red blood cells by generating a white blood cell buffy coat. Both sample types are used in DNA methylation studies. Cell types have unique methylation patterns and processing can impact cell distributions, which may influence comparability. To evaluate differences in cell composition and DNA methylation between buffy coat and whole cord blood samples, cord blood DNA methylation was measured with the Infinium EPIC BeadChip (Illumina) in 8 individuals, each contributing buffy coat and whole blood samples.
Project description:Buffy coat PBMC RNA expression was tested using a custom Nanostring probe panel, to identify general immune and glucocorticoid receptor-associated immune genes. ClinicalTrials.gov Identifier: NCT00824941
Project description:#G017 Burn/Trauma Study. This is a Glue Grant Study comparison between gene expression analyses performed in eight trauma/burn subjects using either a buffy coat isolation of whole blood or using the PAXgene system
Project description:Human DNA methylation Beadchip v1.2 was used to profile n=475 samples from various brain regions of subjects with Huntington's disease and control samples. The main goal of the study was to relate Huntington's disease status to measures of epigenetic age acceleration based on DNA methylation data. To measure DNA methylation age, 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.
Project description:An Infinium microarray platform (HorvathMammalMethylChip40) was used to generate DNA methylation data from n=168 blood samples of a transgenic sheep model of Huntington's disease. 84 transgenic sheep and age matched control sheep.
