DNA methylation anaylsis of placenta samples exposed to variable levels of arsenic during pregnancy. Homo sapiens

Genome-wide profiling of placental DNA methylation in relation to arsenic exposure. The Illumina 450k methylation array was used to profile 343 samples for which 3 different measurements of arsenic exposure were available during gestation. These samples have been collected from the New Hampshire Birth Cohort Study (NHBCS). Overall design: Bisulfite converted DNA was hybridized to the 450k platform and processed at the University of Minnesota Genomic Core
