Project description:An updated representation of S. meliloti metabolism that was manually-curated and encompasses information from 240 literature sources, which includes transposon-sequencing (Tn-seq) data and Phenotype MicroArray data for wild-type and mutant strains.
Project description:Test data used for the evaluation of ESAT performance and results files for data from 3' and 5' end-sequencing RNA-Seq protocols and droplet-based single-cell RNA-Seq.
Project description:Experiment: Establishment of expression profiles in HT, PTC with HT, PTC without HT, and mPTC in comparison to TN samples. TN samples were downloaded as CEL files from the repository of the microarray vendor. Biostatistical analysis focussed in first instance on identifying genes and biofunctions related to HT and PTC with HT.
Project description:Phages are important drivers of bacterial evolution with therapeutic potential as antimicrobials. However, gaps in our understanding of phages and ability to rapidly engineer them with new genetic cargo hinders progress towards phage-based therapies. To address the lack of unbiased, genome-wide mutational tools for phages, we developed transposon mutagenesis employing CRISPR-anti-CRISPR (Acr)-based selection and deep-sequencing (Phage Tn-seq). Transposon mutagenesis was effective for phages with unmodified or hypermodified genomes and a jumbo phage that protects its DNA within a nucleus. Phage Tn-seq enabled phage gene essentiality assignment consistent with structural proteomics and core gene conservation. Insertion biases allowed prediction of transcriptional direction and early injected phage DNA regions. We exploited the method to rapidly deliver new cargo to phage genomes in just a few days and used an AI-designed Acr to expand the phage transposon toolbox. Phage Tn-seq is versatile tool to advance our understanding and applications of phages.
Project description:Naive CD4 T (TN) cells show some degree of heterogeneity. However, mechanisms that alter TN cells are still largely unknown, and physiological importance in the phenotypic alteration of TN cells is unclear. Thus, to reveal the mechanisms that alter TN cell characteristics, we performed transposase-accessible chromatin with high-throughput sequencing (ATAC-seq) on TN cells from different secondary lymphoid organs with different strength of tonic TCR stimulation.
Project description:By taking advantage of the strong genetic interactions between trans-translation and other ribosome rescue systems, we have employed a transposon sequencing (Tn-Seq) to identify potential novel rescue factors in Bacillus subtilis. In addition to the identification the ArfA-type rescue factor BrfA, as well as the RQC elongation actors RqcP and RqcH, our Tn-Seq screen led to the identification of YlmH, a poorly characterized S4-domain-containing protein, as a potential RQC factor. Binding of YlmH to 50S ribosomal subunit was confirmed by proteomics approach.
Project description:Test data used for the evaluation of ESAT performance and results files for data from 3' and 5' end-sequencing RNA-Seq protocols and droplet-based single-cell RNA-Seq. Quantification and analysis of Tophat-aligned (v2.0.9) samples from mouse bone-marrow derived dendritic cells (mBMDC) timecourse (0, 2, 4 and 6 hours) post LPS stimulation and non-diabetic BBDR rat pancreatic islet cells. Since end-sequencing (3' or 5') is used for all samples, alignments are only required for the R2 (sequence-containing) read.
Project description:To perform Tn-seq experiments random distribution of the transposon in the genome of the recipient cells is essential. In case transposon is delivered into the host cell by conjugation, donor may affect the distribution of the transposon in the genome of the recipient cell. Here, we provide two Tn-seq performed with two different donor strains. FX371 corresponds the Tn-seq using E. coli B-2163 as donor strain. FX442 corresponds to the Tn-seq using E. coli MFDpir as donor strain.
Project description:To analyze effects of IL-1b on TN cells, RNA-seq analysis was performed on freshly prepared TN cells (0 h) and TN cells cultured with or without recombinamt IL-1b.
