(Submitter supplied) DNA methylation changes in neuroblastoma, a clinically-heterogeneous pediatric tumor, have been described essentially in promoter regions. We analyzed the DNA methylome of neuroblastoma using high-density microarrays and observed differential methylation not only in promoters but also in intragenic and intergenic regions at both CpG and non-CpG sites. These epigenetic changes showed a non-random distribution relative functional chromatin domains, and targeted development and cancer-related genes, relevant for neuroblastoma pathogenesis. more...

(Submitter supplied) To identify new markers for colorectal cancer we scrutinized the methylation status by methyl-CpG immunoprecipitation followed by global methylation profiling on a CpG island microarray, as altered expression could drive genomic and chromosomal instability observed in these tumors. We show for the first time hypermethylation of MMP9, DNMT3A, and LIG4 in CRC which was confirmed in two independent ethnic CRC patients groups. more...

(Submitter supplied) Methylome-wide association studies (MWAS) are typically performed using microarray technologies that assay only a very small fraction of the CG methylome and entirely miss two forms of methylation that are common in brain and likely of particular relevance for neuroscience and psychiatric disorders. The alternative is the use whole genome bisulfite sequencing, but this approach is not yet practically feasible with the sample sizes required for adequate statistical power. more...

(Submitter supplied) Genome-wide DNA methylation profiles were determined on a set of fresh 44 bladder cancer tissues using normal blood as control. DNA amplicons were prepared using Differential Methylation Hybridization (DMH) method, subsequently hybridized on to the Agilent Human CpG island Microarray. The goal was to unravel the DNA methylation patterns in different subgropus of bladder cancer along with finding markers for progresssion and early diagnosis.

(Submitter supplied) Methylation of CpG islands is associated with transcriptional repression and, in cancer, leads to the abnormal silencing of tumor-suppressor genes. We developed a novel and robust technique that allows the unbiased, genome wide detection of CpG-methylation in limited DNA samples, without applying methylation-sensitive restriction endonucleases or bisulfite-treatment. The approach is based on a recombinant, methyl-CpG binding protein that efficiently binds CpG-methylated DNA depending on its degree of CpG methylation. more...

(Submitter supplied) Methylation of CpG islands is associated with transcriptional repression and, in cancer, leads to the abnormal silencing of tumor-suppressor genes. Genome wide methylation profiling of myeloid leukemia cell lines identified a large number of genes with aberrantly methylated CpG islands. Comparative mRNA expression analysis suggests that more than half of these genes show extremely low or absent expression in normal cells, suggesting that hypermethylation in cancer may be independent of the transcriptional status of the affected gene. more...

(Submitter supplied) 61 human HCCs were analyzed for genome-wide gene expression. Samples were collected at two sites in Germany, Heidelberg (HD) and Hannover (N). The Heidelberg Collection include 40 independent HCC: 19 liver resections and 17 explant liver specimen (4 not determined); median age at surgery was 57 years (range, 16-78), and the male/female ratio was 3:1. All diagnoses were confirmed by histological reevaluation, and use of the samples was approved by the local ethics committee. more...

(Submitter supplied) B-cell precursor acute lymphoblastic leukemia (pre-B ALL) is the most common pediatric cancer. Although the genetic origin of the disease remains unclear, epigenetic modifications including DNA methylation are suggested to contribute significantly to leukemogenesis. We assessed the DNA methylation status of 402,842 CpG-sites across the genome (Illumina 450k array) in tumor and remission samples of 46 pre-B ALL patients, thus generating the most comprehensive single CpG-site resolution pre-B ALL methylomes so far. more...

(Submitter supplied) Here we provided the first single-base resolution DNA methylatome in chicken lungs by whole-genome bisulfite sequencing (MethylC-seq). In addition, two genetically distinct highly inbred chicken lines, Leghorn and Fayoumi, were used to examine how DNA methylation regulates mRNA gene expression between two lines. The methylation profile demonstrated that methylcytosines in the chicken were more likely to occur in CG dinucleotides than in non-CG sites. more...

(Submitter supplied) In order to gain insight into DNA methylation readout, we have established a controlled strategy for profiling genomic targeting of chromatin-interacting factors in vivo. With this approach we determined binding preferences for the methyl-CpG binding domain (MBD) family of proteins, including disease relevant mutants, deletions and isoforms. In vivo binding of MBD proteins occurs as a linear function of local methylation density, and is dependent on functional MBD domain – methyl-CpG interactions. more...
