Detection of aberrant DNA methylation in colorectal carcinoma samples compared to normal human colon

(Submitter supplied) To globally define methylation-’prone’ and -’protected’ CpG islands in colorectal carcinoma we analyzed the methylation status of 23,000 CpG islands of the human genome in ten coleorectal carcinoma samples as well as normal colon using our previously described methyl-CpG immunoprecipitation (MCIp) technique (Gebhard et al. 2006; Schilling and Rehli 2007). This method enriches for highly CpG methylated DNA that can be directly applied to fluorescent labeling and oligonucleotide microarray hybridization without an additional amplification step. more...

Methylation profiling of leukemia cell lines

(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...

Expression profiling of leukemia cell lines

(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...

Molecular rules governing de novo methylation in cancer

(Submitter supplied) De novo methylation of CpG islands is seen in many tumors, but the general rules governing this process are not known. By analyzing DNA from tumors, as well as normal tissues, and by utilizing a wide range of published data, we have been able to identify a well-defined set of tumor targets, each of which has its own “coefficient” of methylation that is largely determined by its inherent relative ability to recruit the polycomb complex. more...

Microarray analysis of gene expression in the livers of C57BL/6J mice fed a choline- and folate-deficient diet

(Submitter supplied) Non-alcoholic steatohepatitis (NASH) is becoming one of the leading causes of hepatocellular carcinoma (HCC), replacing viral HBV-, HCV-, and alcohol-related chronic liver diseases as major etiological risk of factors for HCC. The goal of the present study was to investigate transcriptomic alterations in the livers of male C57BL/6J mice fed a choline- and folate-deficient (CFD) diet. Feeding mice a CFD diet for 12 weeks caused NASH-like liver injury exhibiting uniform morphological features of human NASH. more...

Genome-Wide DNA Methylation Profiles in Hematopoietic Stem and Progenitor Cells Reveal Over-Representation of ETS Transcription Factor Binding Sites

(Submitter supplied) DNA methylation is an essential epigenetic mark that is required for normal development. Knockout of the DNA methyltransferase enzymes in the mouse hematopoietic compartment reveals that methylation is critical for hematopoietic differentiation. To better understand the role of DNA methylation in hematopoiesis, we characterized genome-wide DNA methylation in primary mouse hematopoietic stem cells (HSC), common myeloid progenitors (CMP), and erythroblasts (ERY). more...

The effects of cytosine methylation on general transcription factors

(Submitter supplied) DNA methylation (mC) on CpG sites is the most common epigenetic modification. Recently methylation on non-CpG context was found to widely occur on genomic DNA. However, how non-CpG methylation influences DNA/protein interaction and regulates transcription is unknown. Using single-molecule assays, we studied the interactions of transcription factors (TFs) GR, ER and BMAL1-CLOCK with methylated or unmethylated cognate DNA binding sequences. more...

High-resolution Nanopore methylome-maps reveal random hyper-methylation at CpG-poor regions as driver of chemoresistance in leukemias. [methylation]

(Submitter supplied) Aberrant DNA-methylation at CpG dinucleotides is a hallmark of cancer and is associated with the emergence of resistance to anti-cancer treatment, though molecular mechanisms and biological signifi- cance remain elusive. Genome-scale methylation maps by currently used methods are based on chemical modification of DNA and are best suited for analyses of methylation at CpG-rich regions (CpG islands). more...

De novo DNA methyltransferase activity in colorectal cancer is directed towards H3K36me3 marked CpG island (T7-DNMT3B ChIP-Rx_seq)

(Submitter supplied) The aberrant gain of DNA methylation at CpG islands (CGIs) is frequently observed in colorectal tumours and may silence the expression of tumour suppressors such as MLH1. Current models propose that these CGIs are targeted by de novo DNA methyltransferases (DNMTs) in a sequence-specific manner but this has not been tested. Using ectopically integrated CGIs, we find that aberrantly methylated CGIs are subject to low levels of de novo DNMT activity in colorectal cancer cells. more...
