Project description:Genome wide DNA methylation profiling of peripheral blood cells from WHS and several disease patients. The Illumina Infinium EPIC Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 850,000 CpGs in peripheral blood samples. Samples included, 20 WHS, 1 patient with heterozygous deletion in 4p16.2p15.31, 2 Sotos syndrome patients, 2 Kabuki syndrome patients, 1 CHARGE syndrome patient, and 3 patients who harbor NSD2 de novo variants.

Project description:DNA methylation gradiently changes with age and is likely to be involved in aging-related processes resulting in phenotype changes and increased susceptibility to certain diseases. The Hutchinson-Gilford Progeria Syndrome (HGP) and Werner Syndrome are two premature aging diseases showing features of common aging. Mutations in LMNA and WRN genes were associated to disease onset; however for a subset of patients the underlying causative mechanisms remain elusive. We aimed to evaluate the role of epigenetic alteration on premature aging diseases by performing genome-wide DNA methylation profiling of HGP and WS patients.

Project description:DNA methylation gradiently changes with age and is likely to be involved in aging-related processes resulting in phenotype changes and increased susceptibility to certain diseases. The Hutchinson-Gilford Progeria Syndrome (HGP) and Werner Syndrome are two premature aging diseases showing features of common aging. Mutations in LMNA and WRN genes were associated to disease onset; however for a subset of patients the underlying causative mechanisms remain elusive. We aimed to evaluate the role of epigenetic alteration on premature aging diseases by performing genome-wide DNA methylation profiling of HGP and WS patients. DNA was quantified by Quant-iT PicoGreen dsDNA Reagent (Invitrogen) and the integrity was analyzed in a 1.3% agarose gel. Bisulfite conversion of 600 ng of each sample was perform according to the manufacturer's recommendation for Illumina Infinium Assay. Effective bisulphite conversion was checked for three controls that were converted simultaneously with the samples. 4 ul of bisulfite converted DNA were used to hybridize on Infinium HumanMethylation 450 BeadChip, following Illumina Infinium HD Methylation protocol. Chip analysis was performed using Illumina HiScan SQ fluorescent scanner. The intensities of the images are extracted using GenomeStudio (2010.3) Methylation module (1.8.5) software. Methylation score of each CpG is represented as beta value. Naive B-cells and peripheral blood mononuclear cells were analyzed to correct for the epigenetic effects of the Epstein-Barr virus immortalization (lymphoblastoid cell lines) and cell composition of the samples, respectively.

Project description:Genome wide DNA methylation analysis using blood leukocyte DNA was performed on 15 patients with genomic imprinting disorders (13 Beckwith–Wiedemann syndrome [BWS], two Silver–Russell syndrome [SRS]), and four controls. The Illumina HumanMethylation850 BeadChip was used to obtain DNA methylation profiles at a more than 850,000 CpGs.

Project description:Constitutive heterochromatin is responsible for genome repression of DNA enriched in repetitive sequences, telomeres, and centromeres. In higher eukaryotes, constitutive heterochromatin is mostly segregated at the nuclear periphery, where the interaction with the nuclear lamina makes the genome more resistant to transcription. During physiological and pathological premature aging, heterochromatin homeostasis is profoundly compromised. Here we show that LINE-1 (L1) RNA accumulation is an early event in both typical and atypical progeroid syndromes. Depletion of L1 RNA in cells from different progeroid syndrome patients using specific antisense oligonucleotides (ASO) restores the levels of heterochromatin epigenetic marks, reverses DNA methylation age and counteracts the expression of senescence-associated genes. Moreover, proteome profiling involved in senescence phenotype was partially restored upon depletion of LINE-1 RNA in both Hutchinson-Gilford Progeria Syndrome (HGPS) and Werner syndrome (WRN-/-).

Project description:Genome wide DNA methylation profiling of obstructive sleep apnea (OSA) patients and healthy subjects. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in peripheral blood mononuclear cell samples. Samples included 8 normal subjects and 16 patients with obstructive sleep apnea syndrome.

Project description:Genome-wide analysis of DNA methylation profiles from patients with Sjögren's syndrome with high versus low fatigue levels using the Illumina Infinium HumanMethylation450 Beadchip array. Background Chronic fatigue is a common, disabling, and poorly understood phenomenon. Recent studies indicate that epigenetic mechanisms may be involved in the expression of fatigue, a prominent feature of primary Sjögren’s syndrome (pSS). The aim of this study was to investigate whether DNA methylation profiles of whole blood are associated with fatigue in patients with pSS. Methods 48 pSS patients with high (n=24) or low (n=24) fatigue as measured by a visual analogue scale were included. Genome-wide DNA methylation was investigated using the Illumina HumanMethylation450 BeadChip array.

Project description:DNA methylation differences between Newborns and Nonagenarians The study aimed to compare the DNA methylation differences between newborns and nonagenarians using methylation array technology (450K, Illumina). The identified differently methylated CpG were further analyzed for their presence in diseases related to the aging phenotype (Werner and Progeria syndrome).
