(Submitter supplied) Through parallel processing of genomic DNA with bisulfite and oxidative bisulfite treatments on Illumina 450K arrays we resolved both 5mC and 5hmC in glioblastoma tissues. We developed and applied a novel technique for estimating 5mC, 5hmC, and unmethylated proportions from array data to glioblastoma tissues and compare with normal brain tissue. Genomic distribution of 5hmC was associated with features of transcription despite the glioblastoma genome being relatively depleted of 5hmC. more...

(Submitter supplied) MGMT promoter methylation status is currently the only established molecular prognosticator in IDH wild-type glioblastoma multiforme (GBM). Therefore, we aimed to discover novel therapy-associated epigenetic biomarkers. After enrichment for hypermethylated fractions using methyl-CpG-immunoprecipitation (MCIp), we performed global DNA methylation profiling for 14 long-term (LTS; >36 months) and 15 short-term (STS; 6–10 months) surviving GBM patients. more...

(Submitter supplied) Gene expression profiling revealed over-representation of a distinct (proneural-like) expression signature in long-term survivors that was linked to IDH1/2 mutation. However, among the IDH1/2-wildtype patients, tumors from long-term survivors did not show distinct gene expression profiles and included proneural, classical and mesenchymal glioblastoma subtypes. We performed genome- and/or transcriptome-wide molecular profiling of primary tumor samples from 70 glioblastoma patients of the German Glioma Network, including 23 longterm survivors with >36 months overall survival (OS), 16 short-term survivors with <12 months OS, and 31 patients with intermediate OS

(Submitter supplied) Background: A feature of glioblastoma (GBM) is the cellular and molecular heterogeneity, both within and between tumors. This variability results in a risk for sampling bias and potential tumor escape from future targeted therapy. Heterogeneous gene expression within GBM is well documented, but little is known regarding the epigenetic heterogeneity. We therefore aimed to profile the intra-tumor DNA methylation heterogeneity in GBM. more...

(Submitter supplied) The aim of this study was to perform a genomic profiling of gliomas of Brazilian origin, using array-CGH, MSI analysis and to associate the genomic alterations with TERT and IDH1 mutation status, and correlate the molecular features with clinicopathological characteristics.

(Submitter supplied) Ductal carcinoma in situ (DCIS) is a heterogeneous, pre-invasive lesion associated with an increased risk for future invasive ductal carcinoma. However, accurate risk stratification for development of invasive disease and appropriate treatment decisions remain clinical challenges. DNA methylation alterations are recognized to be early events in the progression of cancer and represent emerging molecular markers that may predict invasive recurrence more accurately than traditional measures of DCIS prognosis. more...

(Submitter supplied) Hydroxymethylcytosine (5hmC) was recently found to be abundantly present in certain cell types including embryonic stem cells. The function of 5hmC is poorly understood. Here we have generated a genome-wide map of 5hmC in human embryonic stem cells (hESCs) by hydroxymethyl-DNA immunoprecipitation followed by massively parallel sequencing (hmeDIP-seq). We found that 5hmC is enriched over enhancers as well as gene bodies, suggesting a potential role of 5hmC in gene regulation. more...

(Submitter supplied) Glioblastomas in adult patients are classified into four subtypes, IDH, MES, RTK I, and RTK II, based on DNA-methylation and RNA-expression data. Tumour subtype transitions are common during treatment, and transitions to the mesenchymal (MES) subtype are associated with therapy resistance and adverse prognosis. Here, we present DNA methylome and histone modification data of glioblastoma primary tumours and find that glioblastoma subtypes differ in their enhancer landscapes. more...

(Submitter supplied) To examine patterns associated with survival, we assembled a cohort of GBM patients whose survival ranges from less than 3 months and up to 10 years, most of which are not bearing isocitrate-dehyderogenase (IDH)-1 mutation and did not undergo prior treatment. We integrated high-resolution mass-spectrometry proteomics and RNA sequencing to examine the yet unresolved proteomic contribution to poor patient outcome, and compared it to the more established transcriptomic contribution and to published single-cell data. more...
