Project description:DNA methylation profiling of cancer and control samples. The Illumina GoldenGate Methylation Cancer Panel I was used to obtain DNA methylation profiles across 1,505 CpG sites CpGs distributed across 807 genes in blood DNA specimens. DNA samples were extracted from blood specimens, bisulfite treated and subsequently used for GoldenGate Methylation Cancer Panel I Array (Illumina) according to manufacturer’s protocol together with normalization methylated, hemimethylated and unmethylated DNA controls (Qiagen).
Project description:The Illumina GoldenGate® methylation array was used to evaluate DNA methylation at 1,505 CpG sites in 807 cancer-related genes in 91 consecutive CRC samples and 28 matched normal colonic mucosa.
Project description:Using primary breast tumors from 162 women from the Kaiser Division of Research Pathways Study and the Illumina GoldenGate methylation bead-array platform, we measured CpG loci associated with cancer-related genes 162 tumor specimens from the initial diagnostic biopsy were obtained from the KPNC tumor biorepository for methylation analysis. All tumor specimens were from patients who did not receive neoadjuvant chemotherapy.
Project description:Genome-wide profiling of DNA methylation in blood leukocytes from Chinese patients with mild cognitive impairment (MCI) and Alzheimer’s disease (AD). The Illumina Infinium MethylationEPIC BeadChip array (850K chip) was used to detect DNA methylation profiles throughout approximately 850,000 CpG sites in peripheral blood white cells of MCI- and AD-affected Chinese patients, as well as cognitively healthy controls. All samples included 20 Chinese patients with MCI, 20 Chinese patients with AD, and 20 cognitively healthy controls.
Project description:We report on the molecular and cellular events observed in two patients treated by gene therapy in 2004. After the initial resolution of bacterial and fungal infections, both patients exhibited silencing of transgene expression due to methylation of the viral promoter, and myelodysplasia with monosomy 7 as a result of insertional activation of EVI1. In line with this observation, a genome wide methylation analysis of 807 cancer related genes revealed a DNA methylation pattern characteristic of MDS and AML patients. Genomic DNA was prepared from peripheral blood cells of patient 1 (d 0 and month 27) and 25 healthy controls including 12 males and 13 females. The GoldenGate Methylation Cancer Panel I array was used to compare methylation degree in 1.505 CpG sites from promoter regions or the first exon of 807 mostly cancer related genes between the patient 1 (d 0 and month 27) and 25 healthy controls.
Project description:DNA Methylation was analyzed in tuberculosis patients without HIV at baseline and 6 months after completion of successful therapy. DNA methylation was also evaluated in TB patients with HIV and in healthy controls without Tuberculosis. 500ng of gDNA was bisulfite treated prior to running the Illumina Infinium MethylEPIC array
Project description:The Illumina GoldenGate® methylation array was used to evaluate DNA methylation at 1,505 CpG sites in 807 cancer-related genes in 91 consecutive CRC samples and 28 matched normal colonic mucosa. Bisulphite converted DNA from the 119 samples (91 CRC, 28 matched normals) were hybridised to the Illumina GoldenGate® methylation array.
Project description:Genome wide DNA methylation profiling of normal and Prostate cancer samples. The Illumina GoldenGate Methylation Cancer Panel I with 1,505 CpG sites selected from 807 genes was used to obtain DNA methylation profiles. Samples included 24 normals and 87 tumors. Bisulphite converted DNA from the 111 samples were hybridised to the Illumina Illumina GoldenGate Methylation array.
Project description:Genomic imprinting is the parent-of-origin-specific allelic transcriptional silencing observed in mammals, which is governed by DNA methylation established in the gametes and maintained throughout the development. The frequency and extent of epimutations associated with the nine reported imprinting syndromes varies because it is evident that aberrant preimplantation maintenance of imprinted differentially methylated regions (DMRs) may affect multiple loci. Using a custom Illumina GoldenGate array targeting 27 imprinted DMRs, we profiled allelic methylation in 8 imprinting defect patients.
