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: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 92 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.
