Project description:We report scM&T-seq, a method for parallel single-cell genome-wide methylome and transcriptome sequencing, allowing discovery of associations between transcriptional and epigenetic variation. Profiling of 61 mouse embryonic stem cells confirmed known links between DNA methylation and transcription. Notably, the method reveals novel associations between heterogeneous methylation of distal regulatory elements and transcriptional heterogeneity of key pluripotency genes. E14 ES cells were grown in either serum/LIF or 2i culture conditions and separated into single cells. RNA-Seq or Bisulfite-Seq libraries were prepared. This Series includes only the Bisulfite-Seq data. The list of 61 samples that passed QC in both BS-seq and RNA-seq is included in "Supplementary Table 1" of the associated manuscript.
Project description:Bisulfite conversion and whole genome-single base next generation sequencing of DNA from a single iPSC clone (CMC28). This method provides exceptional depth of the sequenced methylome. Bisulfite converted DNA from a single iPSC clone (CMC28), and get its high-throughput sequence data with Illumina.

Project description:We performed paired-end poly A+ RNA sequencing using total RNA isolated from U2OS cells that are synchronised into G1, G1/S, S, G2 and M phase of cell cycle.
Project description:We applied the solution hybrid selection approach to the enrichment of CpG islands (CGIs) and promoter sequences from the human genome for targeted high-throughput bisulfite sequencing. A single lane of Illumina sequences allowed accurate and quantitative analysis of 1 million CpGs in more than 21,408 CGIs and 15,946 transcriptional regulatory regions. More than 85% of capture probes successfully yielded quantitative DNA methylation information of targeted regions. In this study, we generated genome-wide, single-base resolution DNA methylation maps in three of the most commonly used breast cancer cell lines.Differentially methylated regions (DMRs) were identified in the 5?-end regulatory regions, as well as the intra- and intergenic regions, particularly in the X chromosome among the three cell lines. The single CpG resolution methylation maps of many known tumor suppressor genes were also established in the three cell lines. Here we present a novel approach that combines solution-phase hybrid selection and massively parallel bisulfite sequencing to profile DNA methylation in targeted CGI and promoter regions. We designed 51,466 single strand DNA oligonucleotides (160-mer) which target 23,441 CGIs and the transcription start sites of 19,369 known genes in the human genome. The synthetic long DNA oligonucleotides were converted into biotinylated RNA probes for solution-phase hybridization capture of target DNA. The captured genomic DNA was treated with sodium bisulfite, amplified by PCR and sequenced using Illumina GA IIx sequencer.
Project description:Cytosine methylation of DNA CpG dinucleotides in gene promoters is an epigenetic modification that regulates gene transcription. While many methods exist to interrogate methylation states, no current methods offer large-scale, targeted, single CpG resolution. We report an approach combining bisulfite treatment followed by RainDance microdroplet PCR with next-generation sequencing to assay the methylation state of 50 genes in the regions 1 kb upstream and downstream of their transcription start sites. Wildtype and hypermethylated Jurkat DNA (New Englad Biolabs) was treated with bisulfite to convert all unmethylated cytosines to uracil. Following bisulfite treatment, targeted amplification was carried out using a custom primer library and microdroplet PCR. PCR product was sheared to 200 bp and ligated to sequencing adapters following standard protocols. Sequencing was conducted with single-end 100 bp reads on an Illumina GAIIx for wild type Jurkat DNA or Jurkat CpG DNA with a single sample per lane.
