Project description:This study consists of 24 genome-wide methylation profiles which have been generated from blood and saliva samples collected from ten volunteers in the Personal Genome Project UK. The Personal Genome Project UK aims to create publicly available genome, health and trait data, and these ten volunteers represent the pilot study (PGP-UK10) and the first three genome donation participants. These samples were bisulphite converted using the EZ DNA methylation kit (Zymo), using the alternative incubation conditions recommended for HumanMethylation450 BeadChip (Illumina). Genome-wide DNA methylation was then profiled using the HumanMethylation450 BeadChip (Illumina).
Project description:The Human Induced Pluripotent Stem Cells Initiative (HipSci) is generating a large, high-quality reference panel of human IPSC lines. This is a pilot submission of mass-spectrometry analyses from 18 induced pluripotent stem cell lines generated by the HipSci project. This submission includes also data for two embryonic stem cell lines, and one reference sample comprising a mixture of 42 IPSC lines. Raw data files for this study can be accessed from the PRIDE database at EMBL-EBI under accession number PXD003903: http://www.ebi.ac.uk/pride/archive/projects/PXD003903.
Project description:Total RNA was extracted from zebrafish embryos collected for one or more alleles identified by the Zebrafish Mutation Project (http://www.sanger.ac.uk/Projects/D_rerio/zmp/). The mRNA was pulled down using polyT oligos attached to magnetic beads and Illumina libraries were prepared using TruSeq Stranded mRNA SamplePreparation Kits (RS-122-2101 and RS-122-2102) according to manufacturer's instructions.

Project description:Total RNA was extracted from morpholically abnormal and sibling wild type embryos identified by the Zebrafish Mutation Project (http://www.sanger.ac.uk/Projects/D_rerio/zmp/). The 3 end of fragmented RNA was pulled down using polyToligos attached to magnetic beads, reverse transcribed, made into Illumina libraries and sequenced using Illumina HiSeq paired-end sequencing. Protocol: Total RNA was extracted from zebrafish embryos using Trizol and DNase treated. Chemically fragmented RNA was enriched for the 3 ends by pulled down using an anchored polyToligo attached to magnetic beads. An RNA oligo comprising part of the Illumina adapter 2 was ligated to the 5 end of the captured RNA and the RNA was eluted from the beads. Reverse transcription was primed with an anchored polyT oligo with part of Illumina adapter 1 at the 5 end followed by 12 random bases, then an 8 base indexing tags, then CG and 14 T bases. An Illumina library with full adapter sequence was produced by 20 cycles of PCR. This data is part of a pre-publication release.

Project description:MicroRNAs (miRNAs) are involved in nearly every biological process examined to date. Mounting evidence show that some spermatozoa specific miRNAs play important roles in the regulation of spermatogenesis and germ cells development, but little is known of the exact identity and function of miRNA in sperm cells or their potential involvement in spermatogenesis and germ cells development. Here, we investigated the spermatozoa miRNA profiles using illumina deep sequencing combined with bioinformatic analysis using zebrafish as a model system. Deep sequencing of small RNAs yielded 12 million raw reads from zebrafish spermatozoa. Analysis showed that the noncoding RNA of the spermatozoa included tRNA, rRNA, snRNA, snoRNA and miRNA. By mapping to the zebrafish genome, we identified 400 novel and 204 conserved miRNAs which could be grouped into 104 families, including zebrafish specific families, such as mir-731, mir-724, mir-725, mir-729 and mir-2185. We report the first characterization of the miRNAs profiling in zebrafish spermatozoa. The obtained spermatozoa miRNAs profiling will serve as valuable resources to systematically study spermatogenesis in fish and vertebrate.
