ABSTRACT: Genome-scale methylome profiling of human pheochromocytomas and paragangliomas (Illumina methylation beadchips) and mouse chromaffin cells (RRBS)
Project description:Genome-scale DNA methylation was analyzed in a large cohort of pheochromocytomas and paragangliomas (PCC/PGL). Consensus clustering identified 3 stable clusters significantly associated with expression subgroups, gene mutations, and clinical parameters. Bisulfite-converted DNA from 145 fresh frozen PCC/PGL and 3 normal adrenal medulla samples were hybridized to Illumina Infinium 27k Human Methylation BeadChips.
Project description:SNP profiles from 78 pheochromocytomas and paragangliomas were analyzed to detect copy number changes and LOH. 78 pheochromocytomas and paragangliomas were analyzed with Illumina Human610-Quad v1.0 BeadChips.
Project description:SNP profiles from 30 pheochromocytomas and paragangliomas were analyzed to detect identical-by-descent haplotypes, highlighting a founder mutation of SDHD in two samples. 30 pheochromocytomas and paragangliomas were analyzed with Illumina Human610-Quad v1.0 BeadChips.
Project description:Genome-scale DNA methylation was analyzed in a cohort of paragangliomas to identify DNA methylation changes. Bisulfite converted DNA from 22 fresh frozen paragangliomas and 2 normal adrenal medulla samples were hybridized to Illumina HumanMethylation450 BeadChips.
Project description:Genome-scale DNA methylation was analyzed in a large cohort of pheochromocytomas and paragangliomas (PCC/PGL). Consensus clustering identified 3 stable clusters significantly associated with expression subgroups, gene mutations, and clinical parameters.
Project description:Genome wide DNA methylation profiling of pheochromocytoma/paraganglioma samples carrying different mutations. The Illumina Infinium EPIC Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 850,000 CpGs. The main goal of this project was to find specific methylation profiles associated to the presence of mutations in the different genetic sub-classes of pheochromocytomas/paragangliomas.
Project description:Genome wide DNA methylation profiling of a paraganglioma sample carrying the DLST-p.Y422C mutation. The Illumina Infinium EPIC Human DNA methylation Beadchip v1.2 was used to obtain a DNA methylation profile across approximately 850,000 CpGs. The main goal of this project was to find specific methylation profiles associated to the presence of mutations in the DLST gene of pheochromocytomas/paragangliomas.
Project description:We report the analysis of DNA methylation in mouse chromaffin cell lines using reduced representation bisulfite sequencing (RRBS). We compared DNA methylation profiles of cell lines with or without a knock-out of Sdhb gene, showing that Sdhb disruption results in a hypermethylator phenotype. Reduced representation bisulfite sequencing of 4 mouse chromaffin cell samples (2 Sdhb wild-type and 2 Sdhb knock-out).
