Project description:Previous studies in animal models of cocaine craving have delineated broad changes in DNA methylation profiles in the nucleus accumbens. A crucial factor for progress in behavioral and mental health epigenetics is the discovery of epigenetic markers in peripheral tissues. Several studies in primates and humans have associated differences in behavioral phenotypes with changes in DNA methylation in T cells and brain. Herein, we present a pilot study (n=27) showing that the T cell DNA methylation profile differentiates persons with a substance use disorder from controls. Intervention with dehydroepiandrosterone (DHEA), previously shown to have a long-term therapeutic effect on human addicts herein resulted in reversal of DNA methylation changes in behavioral pathways associated with the addictive state.
Project description:Genome wide DNA methylation profiling of colorectal cancer cell lines treated with acetyl-11-keto-β-boswellic acid (AKBA) or 5-aza-2’-deoxycytidine (DAC). The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in the colorectal cancer cell line SW48. Samples included non-treated, AKBA-treated, and DAC-treated SW48 cells.
Project description:To determine the differential miRNA levels in heroin addicts, we comparatively profiled plasma miRNA expression of heroin abusers and healthy controls using Agilent Human miRNA Array.
Project description:To determine the differential miRNA levels in methamphetamine addicts, we comparatively profiled plasma miRNA expression of methamphetamine abusers and healthy controls using Agilent Human miRNA Array.
Project description:The impact of drugs inhibiting DNA methylation (5-aza-2'-deoxycytodine, DAC) and EZH2 (EPZ-6438) on the neuroblastoma methylome was analyzed in two neuroblastoma cell lines. Parallel analyses investigated associated changes in histone modification and RNA expression. The neuroblastoma cell lines Be(2)-C and IMR5-75 were treated with a combination of DAC and EPZ-6438. Controls were treated with solvent (DMSO). DNA was isolated, bisulphite converted and hybridised to the llumina HumanMethylation450 BeadChip
