Genome-scale DNA methylation maps of pluripotent and differentiated cells

Project description:We report the generation and analysis of genome-scale DNA methylation profiles at nucleotide resolution in mammalian cells. Using high-throughput Reduced Representation Bisulfite Sequencing (RRBS) and single-molecule-based sequencing, we generated DNA methylation maps covering the vast majority of CpG islands, and a representative sampling of conserved non-coding elements, transposons and other genomic features, for murine embryonic stem (ES) cells, ES-derived and primary neural cells, and eight other primary tissues. Several key findings emerge from the data. First, DNA methylation patterns are better correlated with histone methylation patterns than with the underlying genome sequence context. Second, methylation of CpGs are dynamic epigenetic marks that undergo extensive changes during cellular differentiation, particularly in regulatory regions outside of core promoters. Third, analysis of ES-derived and primary cells reveals that 'weak' CpG islands associated with a specific set of developmentally regulated genes undergo aberrant hypermethylation during extended proliferation in vitro, in a pattern reminiscent of that reported in some primary tumors. More generally, the results establish RRBS as a powerful technology for epigenetic profiling of cell populations relevant to developmental biology, cancer and regenerative medicine. Keywords: High-throughput Reduced Representation Bisulfite Sequencing (RRBS), Illumina, cell type comparison Reduced representation bisulfite sequencing (MspI,~40-220bp size fraction) of 18 murine cell types.

Analysis of DNA methylation in a three-generation family reveals widespread genetic influence on epigenetic regulation

Project description:To assess variation and inheritance of genome-wide patterns of DNA methylation simultaneously in humans, we applied reduced representation bisulfite sequencing (RRBS) to somatic DNA from six members of a three-generation family. Reduced representation bisulfite sequencing was applied to genomic DNA from leukocytes of 6 family members and two unrelated individuals.

Genome-scale DNA methylation maps of mouse chromaffin cells with or without Sdhb knock-out.

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).

Quality evaluation of Methyl Binding Domain based kits for enrichment DNA-methylation sequencing

Project description:Purpose: to compare different Methyl Binding Domain (MBD) based kits for DNA-methylation sequencing using Reduced Representation Bisulfite Sequencing (RRBS) data for validation, and to determine whether data quality can also be derived from inherent sequence data characteristics MBD-seq using 5 different kits (MethylCap, MethylCollector, MethylCollector Ultra, MethylMiner, MethylMagnet) was applied on 3 commonly used cell lines (DU145, HCT15, PC3), for which also RRBS data were generated.

Genotyping of E14 mouse embryonic stem cells by sequencing

Project description:More than 2x10E9 sequences made on Illumina platform derived from the genome of E14 embryonic stem cells cultured in our laboratory were used to build a database of about 2.7x10E6 single nucleotide variant. The database was validated using other two sequencing datasets from other laboratory and high overlap was observed. The identified variant are enriched on intergenic regions, but several thousands reside on gene exons and regulatory regions, such as promoters, enhancers, splicing site and untranslated regions of RNA, thus indicating high probability of an important functional impact on the molecular biology of this cells. We created a new E14 genome assembly including the new identified variants and used it to map reads from next generation sequencing data generated in our laboratory or in others on E14 cell line. We observed an increase in the number of mapped reads of about 5%. CpG dinucleotide showed the higher variation frequency, probably because of it could be target of DNA methylation. We performed a reduced representation bisulfite sequencing on E14 cell line to test our new genome assembly with respect to the mm9 genome reference. After mapping and methylation status calling, we obtained an increase of about 120,000 called CpG and we avoided about 20,000 wrong CpG calling. genotyping of E14 embryonic stem cells (ESCs) and Reduced representation Bisulfite Sequencing (RRBS) of E14 ESCs.
