Project description:There is strong epidemiologic evidence supporting that exposure to inorganic arsenic (iAs) exposure is responsible for a myriad of adverse health effects, including carcinogenesis of the bladder. This research aimed to identify novel epigenetic biomarkers of iAs exposure in target cells within a human population. Here we assessed genome-wide, gene-specific promoter DNA methylation levels assessed in exfoliated human bladder uroepithelial cells (BECs) in relationship to BEC iAs, monomethylated As (MMAs), dimethylated As (DMAs), and total As (tAs) concentrations from 46 individuals with varying levels of As exposure in Chihuahua, Mexico. These analyses identified genes with increased methylation associated with BEC iAs(III+V), MMAs(III+V), and tAs(III+V). These genes were enriched for signaling related to metabolic disease and cancer.
Project description:To examine the global impact of iAs on DNA methylation patterns. Genomic DNA was Bisulfite converted and analyzed using Mini methly-seq.

Project description:Genome wide DNA methylation profiling of whole blood in schizophrenia patients and healthy subjects of different ages. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 480,000 CpGs. Dataset included 62 schizophrenia patients and 33 healthy subjects from Dutch descent.
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.
