Project description:Time-course ChIP-seq analysis of SP1-ERT2 that permits the measurement of SP1 binding dynamics at target sites on a genome-wide scale in human cells.
Project description:This study examines genome-wide expression of the phenanthrene-degrading Sphingomonas sp. LH128 as a response to short-term starvation stress. For this purpose, the strain was subjected to complete nutrient starvation for 4h after growth on a rich medium. Survival was monitored by plating and transcriptomic response was determined by whole-genome microarray analysis. The data showed no major differences were obsrved in gene expression and the viability of the cells were not affected during short-term incubation time
Project description:To verify genes that are directly regulated by BysR, we used DNA affinity purification sequencing analysis (DAP-seq) for genome-wide recognition of BysR binding sites in vitro. The HALO-fusion BysR protein was successfully expressed and purified. After affinity purification and sequencing, at least 22 million double-end reads per sample were generated and with > 99 % of reads uniquely mapped to the JP2-270 genome. A total of 470 enriched common peaks of two replicates with –log10(P-value) ≥ 2 were called . The mean width of DAP-seq peaks was < 1,000. In total, 367 (78%) of these peaks were found to locate in the -1 kbp to 1 kbp regions by the analysis of peak summit positions relative to the start codons of JP2-270 open reading frames.
