Project description:Genome wide DNA methylation profiling of muscle cells extracted from healthy donors at different ages. The Illumina Infinium Human Methylation 450 BeadChip was used to obtain DNA methylation profiles across > 485,000 methylation sites. The muscle cells were extracted from young adults (18-40 years old) and elderly (>70 years old)(n=3 per group, 2 groups : Young and aged adult). Bisulphite converted DNA from the 6 samples were hybridized to the Illumina Infinium Human Methylation 450 BeadChip
Project description:Genome wide DNA methylation profiling of primary penile squamous cell carcinoma samples with lymphnode metastasis. The Illumina Infinium 450 K Human Methylation was used to obtain DNA methylation profiles in surgical frozen samples. Among the 25 samples, fifteen was infected with HPV, and the others were HPV negative.
Project description:Genome wide DNA methylation profiling of Chinese Han male semen samples. The Illumina Human Methylation 450 Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs. Samples included 3 young males (aged 24, 25 and 25 years old) and 3 aged males (aged 63, 60 and 55 years old).
Project description:Impaired ability of insulin to stimulate cellular glucose uptake and regulate metabolism, that is insulin resistance (IR), links adiposity to metabolic disorders such as type 2 diabetes (T2D), dyslipidemia and cardiovascular disease (Langenberg, 2012). Both genetic and epigenetic factors are implicated in development of systemic IR (Vaag, 2001). IR is characterized by elevated levels of fasting insulin in the general circulation. The aim of this study is to explore whether white adipose tissue (WAT) epigenetic dysregulation is associated with systemic IR by global CpG methylation and gene expression profiling in subcutaneous and visceral adipose tissue. A secondary aim is to determine whether the DNA methylation signature in peripheral blood mononuclear cells reflect WAT methylation, and can be used as marker for systemic IR. DNA methylation was analyzed in DNA extracted from SAT (subcutaneous adipose tissue) and VAT (visceral adipose tissue) pieces, as well as PBMCs (peripheral blood mononuclear cells), using the Infinium Human Methylation 450 BeadChip assay. This data is from PBMCs.
