Project description:H3K4me1 binding in murine pre-B cells detected by ChIP-seq. For the ChIP-seq, input and immunoprecipitated DNA was given to the TSRI Next Generation Sequencing Core (the Scripps Research Institute, La Jolla, CA, US), where it was prepared for massively parallel sequencing on Illumina HiSeq2000.

Project description:Given the facilities for whole genome sequencing with next-generation sequencers, structural and functional gene annotation is now only based on automated prediction. However, errors in terms of gene structure are still frequently reported especially for the correct determination of initiation start codons. Here, we propose a strategy to enrich and detect protein N-termini by mass spectrometry in order to refine genome annotation. After selective protein N-termini derivatization using (N-Succinimidyloxycarbonylmethyl)tris(2,4,6-trimethoxyphenyl)phosphonium bromide (TMPPAc-OSu) as labeling reagent, protein digestion was performed with three proteases in parallel. TMPP-labeled N-terminal-most peptides were further resolved from internal peptides by the COmbined FRActional DIagonal Chromatography (COFRADIC) sorting methodology before analysis with tandem mass spectrometry. We refined the annotation of the genome of a model marine bacterium, Roseobacter denitrificans.

Project description:Mouse genetic crosses were established between the PyMT model of metastatic breast cancer and MOLF strain. Tumors were harvested from the animals for gene expression analysis to identify genes and network modules associated with progression to distant metastatic disease. 30 samples from the MOLF cross were assayed using Illumina next generation sequencers

Project description:DNA methylation is a complex epigenetic marker that can be analysed using a wide variety of methods. Interpretation and visualisation of DNA methylation data can mask complexity in terms of methylation status at each CpG site, cellular heterogeneity of samples and allelic DNA methylation patterns within a given DNA strand. Bisulfite sequencing is considered the gold standard, however visualisation of massively parallel sequencing results remains a significant challenge. We created a program called Methpat that facilitates visualisation and interpretation of bisulfite sequencing data generated by massively parallel sequencing. To demonstrate this, we performed multiplex PCR that targeted 48 regions of interest across 95 human samples. The regions selected included known gene promoters associated with cancer, repetitive elements, known imprinted regions and mitochondrial genomic sequences. We interrogated a range of samples including human cell lines, primary tumours and primary tissue samples. Methpat generates two forms of output: a tab delimited text file for each sample that summarises DNA methylation patterns and their read counts for each amplicon and a HTML file that summarises this data visually. Methpat can be used with publicly available whole genome bisulfite sequencing (WGBS) and reduced representation bisulfite sequencing (RRBS) datasets with sufficient read depths. Using Methpat, complex DNA methylation data derived from massively parallel sequencing can be summarised and visualised for biological interpretation. By accounting for allelic DNA methylation states and their abundance in a sample, Methpat can unmask the complexity of DNA methylation and reveal further biological insight in existing datasets.

Project description:In this study we developed MPE-seq, a method for the genome-wide characterization of chromatin that involves the digestion of nuclei with methidiumpropyl-EDTA-Fe(II) [MPE-Fe(II)] followed by massively parallel sequencing. Like micrococcal nuclease (MNase), MPE-Fe(II) preferentially cleaves the linker DNA between nucleosomes. We also performed MNase-seq as a comparison. We further performed ChIP-seq using chromatin samples obtained by MPE-Fe(II) or MNase digestion of nuclei. Nuclei from J1 mouse embryonic stem cells were treated with MPE-Fe(II) or MNase. The isolated DNA was sequenced by Illumina HiSeq sequencers. Some of the digested chromatin was studied by performing ChIP-seq using antibodies against histone H2B or H3.

Project description:We first report the use of next-generation massively parallel sequencing technologies and de novo transcriptome assembly to gain insight into the wide range of transcriptome of Hevea brasiliensis. The output of sequenced data showed that more than 12 million sequence reads with average length of 90nt were generated. Totally 48,768 unigenes (mean size = 488 bp) were assembled through transcriptome de novo assembly, which represent more than 3-fold of all the sequences of Hevea brasiliensis deposited in the GenBank. Assembled sequences were annotated with gene descriptions, gene ontology and clusters of orthologous group terms. Total 37,373 unigenes were successfully annotated and more than 10% of unigenes were aligned to known proteins of Euphorbiaceae. The unigenes contain nearly complete collection of known rubber-synthesis-related genes. Our data provides the most comprehensive sequence resource available for study rubber tree and demonstrates the availability of Illumina sequencing and de novo transcriptome assembly in a species lacking genome information.

Project description:We report here the use of next-generation massively parallel sequencing technologies and de novo transcriptome assembly to gain insight into the wide range of transcriptome of two Hevea brasiliensis clones (RY8-79 and PR107). The output of sequenced data showed that more than 26 million sequence reads with average length of 90nt were generated in both clones. Totally 51829 unigenes (mean size = 640 bp) were assembled through transcriptome de novo assembly, which represent more than 16-fold of all the sequences of Hevea brasiliensis deposited in the GenBank. Assembled sequences were annotated with gene descriptions, gene ontology and clusters of orthologous group terms. Base on limit rule with FDR≤0.001 and |log2 Ratio|≥1, 6726 different expression unigenes (3018 up and 3708 down) were detected as PR107 versus RY8-79. Functional analysis showed mass of categories were reprogrammed between two clones, which relate latex generation and expelling difference between them. As a comparative transcriptome analysis, the results obtained here will greatly expand our understanding of physiological differences among varieties in molecular level and will contribute t The transcriptome of latex in Hevea brasiliensis
