Project description:The manuscript by D. Licastro and colleagues “Promiscuity of enhancer, coding and non-coding transcription functions in ultraconserved sequence elements” presents an overview of experimental and computational approaches employed by the authors to perform a multi-facet characterization of ultraconserved elements (UCEs). The authors present an interesting analysis where they investigate the transcription of UCEs in mouse development at different stages by conductin an microarray experiment. Some of these results are further verified by RT-PCR.

Project description:Our data demonstrate the suitability of target capture technology for purifying very low quantities of Leptospira DNA from biological samples where the human genome is in vast excess. This enables deep sequencing of partial Leptospira genomes directly from clinical samples using next generation technologies and genotyping.
Project description:NG-Capture-C profiling of chromatin interactions (using DpnII 3C and Oligo nucleotide sequence capture followed by Next generation sequencing) of enhancers, promoters and CTCF/Rad21 binding sites throughout a ~600kb region of the mouse Pax6 locus in three expression states, High (β-TC3), On (MV+) and OFF (RAG). β-TC3 cell are a mouse pancreatic β cell derived from mouse insulinoma, MV+ a lens epithelium cell line and RAG a mouse kidney adenocarcinoma cell line.
Project description:Inserting large DNA payloads (>5 kb) into specific genomic sites of mammalian cells remains challenging. We have merged the strengths of different classes of site-specific recombinases and combine these with CRISPR/Cas9-mediated homologous recombination to develop a strategy for targeted DNA integration of huge constructs (e.g. >170 kb) as well as stringent site-specific replacement of genomic fragments >50 kb in size in human induced pluripotent stem cells. In order to validate the genome integrity of the payloads integrated by STRAIGHT-IN (Serine and Tyrosine Recombinase Assisted Integration of Genes for High-Throughput INvestigation), we performed next generation sequencing (i.e. whole genome and targeted capture sequencing) on the resulting genetically modified cell lines. We have deposited here the raw data.
Project description:One of the cornerstones of an effective biodefense strategy is the ability to detect infectious agents with a high degree of sensitivity and specificity in the context of a complex sample background. The nature of the B. anthracis genome, however, renders specific detection difficult, due to close homology with B. cereus and B. thuringiensis. We therefore elected to determine the efficacy of next-generation sequencing analysis and microarrays for detection of B. anthracis in an environmental background. We applied next-generation sequencing to titrated genome copy numbers of B. anthracis in the presence of background nucleic acid extracted from aerosol and soil samples. We found next-generation sequencing to be capable of detecting as few as 10 genomic equivalents of B. anthracis DNA per nanogram of background nucleic acid. Detection was accomplished by mapping reads to either a defined subset of reference genomes or to the full GenBank database. Moreover, sequence data obtained from B. anthracis could be reliably distinguished from sequence data mapping to either B. cereus or B. thuringiensis. We also demonstrated the efficacy of a microbial census microarray in detecting B. anthracis in the same samples, representing a cost-effective and high-throughput approach, complementary to next-generation sequencing. This Series contains the NimbleGen array data only (no next-generation sequencing data). B. anthracis DNA was spiked at 6 different concentrations (1, 10, 100, 1000, 10000 and 100000 genome copies) into 1 ng of background nucleic acids extracted either from a soil sample or from an aerosol (air filter) sample. Two replicates of each combination of B. anthracis copy number and background sample were analyzed.
Project description:The purpose of the this study is to determine the prevalence of germline cancer susceptibility gene mutation among Chinese population, and to find best ways to screen patients with colorectal cancer in China. To accomplish this objective, the investigators will establish a large sample database of hereditary colorectal cancer related information using multigene panel testing based on Next-Generation Sequencing.
