(Submitter supplied) Four cervical carcinoma cell lines (C4I, CaSki, HeLa, SiHa) were treated with epigenetic modifying drugs 5-aza-2’-deoxycytidine and trichostatin A. Such treatment leads to reactivation of genes that are epigenetically silenced in cancer by aberrant methylation; reactivated genes were then identified by microarray profiling. Subsets consist of 2 biological repeats and 2 dye-flip experiments for each repeat for CaSki cell line, and 3 repeats, each with 2 dye-flip experiments for C4I, HeLa, Caski cell lines. more...

(Submitter supplied) Microarray-based DNA methylation and gene expression profiling was carried out using a panel of prostate cancer cell lines (LNCaP-FGC, DU-145, and PC-3) and the control normal prostate RWPE1 cell line. The identification of prostate cancer-specific methylation markers was based on the following criteria: a difference in DNA methylation level (β) of at least 0.5, and at least a 2-fold difference in expression level between cancer and control cells. more...

(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) Promoter methylation profiles are proposed as potential prognosis and/or diagnosis biomarkers in cervical cancer. Up to now, little is known about the promoter methylation profile and expression pattern of stem cell (SC) markers during tumor development. In this study, we were interested to identify SC genes methylation profiles during cervical carcinogenesis. A genome-wide promoter methylation screening revealed a strong hypermethylation of Undifferentiated cell Transcription Factor 1 (UTF1) promoter in cervical cancer in comparison with normal ectocervix. more...

The 61 genes were selected to validate by quantitative methylation specific PCR (qMSP) and bisulfite pyrosequencing in further processes. A CpG islands methylator phenotype (CIMP) was confirmed at 14 candidates in an independent set contained a spectrum of scraping cells form abnormal cervical lesions. more...

(Submitter supplied) DNA methylation is tightly linked with gene expression regulation and has long been regarded a stable epigenetic mark in postmitotic cells. However, it recently became clear that postnatal brains appear to show stimulus-induced de novo CpG methylation or active demethylation related to neuronal plasticity. Due to striking homologies between the brains of birds and mammals, songbirds, especially the zebra finch, propose an attractive model for investigating the genome-wide DNA methylation profile and DNA methylation reconfiguration during brain development. more...
