Project description:Histone H3 is assembled into nucleosomes during replication but is replaced by the H3.3 variant at sites of active transcription. Thus replacement levels provide a quantitative measure of histone turnover during transcriptional elongation and other active processes in dividing cells. Here we provide new insights into epigenetic regulation with the first genome-wide chromatin profile at 100-bp resolution, based on measurements of H3.3 levels throughout the Drosophila genome. These data are unpublished. Keywords: Chromatin affinity-purification on microarray
Project description:This SuperSeries is composed of the following subset Series: GSE21820: Genome-wide characterization of PhoB binding profile in Escherichia coli (gene expression data) GSE21856: Genome-wide characterization of PhoB binding profile in Escherichia coli (ChIP-chip data) Refer to individual Series
Project description:The mass spectrometry proteomics data of outer membrane vesicles of wide-type Escherichia coli Nissle 1917 and engineered Escherichia coli Nissle 1917
Project description:Intervention type:DRUG. Intervention1:Huaier, Dose form:GRANULES, Route of administration:ORAL, intended dose regimen:20 to 60/day by either bulk or split for 3 months to extended term if necessary. Control intervention1:None.
Primary outcome(s): For mRNA libraries, focus on mRNA studies. Data analysis includes sequencing data processing and basic sequencing data quality control, prediction of new transcripts, differential expression analysis of genes. Gene Ontology (GO) and the KEGG pathway database are used for annotation and enrichment analysis of up-regulated genes and down-regulated genes.
For small RNA libraries, data analysis includes sequencing data process and sequencing data process QC, small RNA distribution across the genome, rRNA, tRNA, alignment with snRNA and snoRNA, construction of known miRNA expression pattern, prediction New miRNA and Study of their secondary structure Based on the expression pattern of miRNA, we perform not only GO / KEGG annotation and enrichment, but also different expression analysis.. Timepoint:RNA sequencing of 240 blood samples of 80 cases and its analysis, scheduled from June 30, 2022..
Project description:We report the application of single-molecule-based sequencing technology for high-throughput profiling of transcription start sites for Escherichia coli under different conditions. By obtaining sequence from 5' RACE (rapid amplification of cDNA ends) followed by deep sequencing, we generated genome-wide TSS (transcription start site) maps for E. coli. This TSS-map was integrated with ChIP-chip data generated for 6 sigma factors in E. coli, resulting in reconstruction of sigma factor network in E. coli.
