(Submitter supplied) Genomic DNA from 6 pure EC and 2 normal testis was fragmented and immunoprecipitated with anti-5mC monoclonal antibodies by MeDIP. After IP, DNA was purified and amplified using Whole Genome Amplification. Subsequently, DNA was biotin-labeled and hybridized to Human Tiling Array 2.0R Chips (Affymetrix) according to the manufacturer’s instruction. Raw data (CEL files) were normalized and analyzed by TAS (Affymetrix). more...

(Submitter supplied) Here we present an approach for the mapping of unmethylated DNA. Our technique is based on DNA methyltransferase-directed transfer of activated groups (mTAG) and covalent biotin tagging of unmodified CpG sites followed by affinity enrichment and interogation on tiling microarrays or next generation sequencing.

(Submitter supplied) Altered gene expression patterns in human diseases reflect perturbations in the transcriptional networks that regulate cellular state. In breast cancer, Nuclear Receptors (NRs) play a prominent role in governing gene expression. NRs have prognostic utility and are therapeutically important targets. Here we describe a complete regulatory map for twenty-four NR proteins that are expressed in the breast cancer cell line MCF-7, as well as fourteen additional breast cancer associated transcription factors (TFs) and six key chromatin state markers.

(Submitter supplied) 5-hydroxymethylcytosine (5-hmC), a derivative of 5-methylcytosine (5-mC), is abundant in the brain for unknown reasons. We mapped the genomic distribution of 5-hmC and 5-mC in human and mouse tissues using glucosylation of 5-hmC coupled with restriction enzyme digestion, and interrogation on microarrays. We detected 5-hmC enrichment in genes with synapse-related functions in the brain. We also identified significant, tissue-specific differential distributions of these DNA modifications at the exon-intron boundary, in both human and mouse. more...

(Submitter supplied) DNA from Epstein-Barr virus (EBV)-transformed lymphocyte cell lines (LCLs) has proven very useful for studies of genetic sequence polymorphisms. Whether EBV-LCL DNA is suitable for methylation studies is less clear. We conduct a genome-wide methylation investigation using an array set with 45 million probes to investigate the methylome of EBV-LCL DNA and technical duplicates of whole blood (WB) DNA from the same 10 individuals. more...

(Submitter supplied) DNA amplification, particularly of chromosomes 8 and 11, occurs frequently in breast cancer and is a key factor in tumorigenesis, often associated with poor prognosis. The mechanisms involved in the amplification of these regions are not fully understood. Studies from model systems have demonstrated that palindrome formation can be an early step in DNA amplification, most notably seen in the breakage-fusion-bridge (BFB) cycle. more...

We analyzed p73 activity using a combination of ChIP-on-Chip and gene expression profiling, both at baseline and after treatment with the mTOR inhibitor rapamycin. We report the first comprehensive analysis of p73 binding across the genome. Furthermore, we re-analyzed this p73 cistrome after perturbation with rapamycin, an inhibitor of mTOR and inducer of p73. more...

(Submitter supplied) Estrogen receptor alpha (ERα) expression in breast cancer is predictive of response to endocrine therapy, however resistance is common in ERα-positive tumors that over-express the growth factor receptor ERBB2. Even in the absence of estrogen, ERα can be activated by growth factors including the epidermal growth factor (EGF). EGF induces a transcriptional program distinct from estrogen, however the mechanism of the stimulus-specific response is unknown. more...

(Submitter supplied) HPV-associated head and neck cancers (HNSCCs) have a distinct risk profile and appreciate a prognostic advantage compared to HPV-negative HNSCC. To assess the genome-wide methylation changes in HPV(+) and HPV(-) tumors, we analyzed DNA methylation and expression patterns in two HPV(+) and two HPV(-) cell lines. HPV(+) tumors have overall higher DNA methylation in genic and LINE1 regions than HPV(-) tumors, and polycomb repressive complex 2 (PRC2) targets tend to be much more highly methylated in HPV(+) cells.

(Submitter supplied) Surprisingly few pathways signal between cells, raising questions about mechanisms for tissue-specific responses. In particular, Wnt ligands signal in many mammalian tissues, including the intestinal epithelium, where constitutive signaling causes cancer. Genome-wide analysis of DNA cis-regulatory regions bound by the intestine-restricted transcription factor CDX2 in colonic cells uncovered highly significant over-representation of sequences that bind TCF4, a transcriptional effector of intestinal Wnt signaling. more...

(Submitter supplied) Androgen signaling through the androgen receptor (AR), a ligand-dependent transcription factor within the steroid receptor superfamily, plays an important role in the development and maintenance of many tissues. In muscle, androgens act as anabolic agents that increase both muscle mass and strength; however, a key unanswered question is the mechanism through which AR-mediated gene expression leads to these effects. more...

(Submitter supplied) FOXP3 is essential for the stability and function of nTReg. We have characterised the FOXP3-dependent cis-regulatory network through a combination of whole genome ChIP-on-chip and transcriptional profiling of primary human nTreg cells . Human nTreg cells were isolated from cord blood and expanded ex vivo (day9). These analyses identified approximately 8,000 high quality FOXP3 binding sites the majority (85%) of which were located in proximity to annotated genes . more...

(Submitter supplied) A series of reports over the last few years have indicated that a much larger portion of the mammalian genome is transcribed than can be accounted for by currently annotated genes, but the quantity and nature of these additional transcripts remains unclear. Here, we have used data from single- and paired-end RNA-Seq and tiling arrays to assess the quantity and composition of transcripts in PolyA+ RNA from human and mouse tissues. more...
