Identification of a CpG island methylator phenotype that defines a distinct subgroup of glioma.
We have profiled promoter DNA methylation alterations in 272 glioblastoma tumors in the context of The Cancer Genome Atlas (TCGA). We found that a distinct subset of samples displays concerted hypermethylation at a large number of loci, indicating the existence of a glioma-CpG island methylator phenotype (G-CIMP). We validated G-CIMP in a set of non-TCGA glioblastomas and low-grade gliomas. G-C...
متن کاملTitle page Title: The CpG island methylator phenotype correlates with long-range epigenetic silencing in colorectal cancer Running title: CIMP correlates with LRES in colorectal cancer
The CpG island methylator phenotype (CIMP), characterized by an exceptionally high frequency of methylation of discrete CpG islands, is observed in 18% to 25% of sporadic colorectal cancers (CRCs). Another hypermethylation pattern found in CRCs, termed LRES (long-range epigenetic silencing), is associated with DNA/histone methylation in three distinct gene clusters at chromosome 2q14.2, demonst...
متن کاملIsocitrate dehydrogenase 1 R132C mutation occurs exclusively in microsatellite stable colorectal cancers with the CpG island methylator phenotype.
The CpG Island Methylator Phenotype (CIMP) is fundamental to an important subset of colorectal cancer; however, its cause is unknown. CIMP is associated with microsatellite instability but is also found in BRAF mutant microsatellite stable cancers that are associated with poor prognosis. The isocitrate dehydrogenase 1 (IDH1) gene causes CIMP in glioma due to an activating mutation that produces...
متن کاملG-Cimp Status Prediction Of Glioblastoma Samples Using mRNA Expression Data
Glioblastoma Multiforme (GBM) is a tumor with high mortality and no known cure. The dramatic molecular and clinical heterogeneity seen in this tumor has led to attempts to define genetically similar subgroups of GBM with the hope of developing tumor specific therapies targeted to the unique biology within each of these subgroups. Recently, a subset of relatively favorable prognosis GBMs has bee...
متن کاملGlioma CpG Island Methylator Phenotype (G-CIMP): Biological and Clinical Implications.
Gliomas are a heterogeneous group of brain tumors with distinct biological and clinical properties. Despite advances in surgical techniques and clinical regimens, treatment of high-grade glioma remains challenging and carries dismal rates of therapeutic success and overall survival. Challenges include the molecular complexity of gliomas, as well as inconsistencies in histopathological grading, ...
