The discovery that the Ten-Eleven Translocation (TET) hydroxylases cause DNA demethylation has fundamentally changed the notion of how DNA methylation is regulated. Clonal analysis of the hematopoetic stem cell compartment suggests that TET2 mutations can be early events in hematologic cancers and recent investigations have shown TET2 mutations in diffuse large B-cell lymphoma. However, the detection rates and the types of TET2 mutations vary, and the relation to global methylation patterns has ...[more]

TET2 loss-of-function mutations associate with a DNA hypermethylation signature in diffuse large B-cell lymphoma (DNA methylation)

Project description:Genome wide DNA methylation profiling of patient samples with TET2 mutations and Wild type TET2 status . The Illumina Infinium HumanMethylation 450_15017482_v.1.1 was used to obtain DNA methylation profiles across approximately 482,421 CpGs in fresh frozen lymphoma samples. Samples include 19 TET2 wild type and 12 TET2 mutant samples. Bisulphite converted DNA from the 31 samples were hybridised to the Illumina Infinium HM450K Human Methylation Beadchip v1.2

Methylation profiling by array of subcutaneous fat derived from 856 TwinsUK participants

Project description:Epigenetic changes such as DNA methylation variation are known to play a role in gene regulation and common disease susceptibility. Little is known about the genome-wide frequency, localization and function of such changes and how they are regulated by genetic and environmental factors. We have utilized the MuTHER resource and generated methylation profiles across multiple tissues conducted in a large set of female individuals that allows systematic dissection of genetic and non-genetic effects on DNA methylation. DNA methylation was quantified in subcutaneous fat and skin derived from 648 TwinsUK participants using the Infinium HumanMethylation450 BeadChips. Data from transcription profiling of skin, adipose fat and lymphoblastoid cell lines (LCLs) from the same set of TwinsUK participants have been deposited in ArrayExpress under accession number E-TABM-1140 (https://www.ebi.ac.uk/arrayexpress/experiments/E-TABM-1140).

Methylation data as part of an Integrated analysis of oligodendroglial tumours

Project description:A Cartes d'Identite des Tumeurs (CIT) project from the french Ligue Nationale Contre le Cancer (http://cit.ligue-cancer.net: Oligodendroglial tumours (OT) are a heterogeneous group of gliomas. Three molecular subgroups are currently distinguished based on the IDH mutation and the 1p/19q co-deletion. Here we performed an integrated analysis of the transcriptome, genome and methylome of 156 OT. Beyond the 3 well-known molecular classes, our multi-omics classification revealed 3 subgroups within 1p/19q co-deleted tumours, associated with different expression patterns of oligodendroglial progenitor cell (OPC), astrocytic, oligodendrocytic and neuronal lineage genes. The validity of these 3 subgroups was confirmed on public datasets. The OPC-like group was associated with a more aggressive histological and genomic profile and with MYC activation that occurred through various alterations including MYC locus genomic gain, MYC exon 3 hypo-methylation and down-regulation of microRNA-34b/c. In the lower grade glioma TCGA dataset, the OPC-like group was associated with a poorer outcome independently from histological grade. Our study unravels previously unrecognized heterogeneity among 1p/19q co-deleted tumours.

Selecting patients with metastatic clear-cell renal cell carcinoma (m-ccRCC) who might benefit from treatment with targeted tyrosine kinase inhibitors (TKIs) is a challenge. Our aim was to identify molecular markers associated with outcome in m-ccRCC patients treated with sunitinib.\
