ChIP-seq analysis reveals the direct targets of GltR in the P. aeruginosa genome

ABSTRACT: we performed ChIP-seq assays to identify in vivo targets of GltR. The plasmid mini-gltR-flag-lacz was constructed and the resultant plasmid was fused to P. aeruginosa strain PAO1, yielding PAO1/mini-gltR-flag-lacz. We investigated GltR-binding to the chromosome of PAO1 during growth with glucose by ChIP-Seq. Sequence reads obtained from three independent ChIP-Seq experiments using anti-flag antibody and mapped to the P. aeruginosa PAO1 genome.Using the MACS software,we identified 55 enriched loci (q-value < 0.05) harboring GltR-binding peaks, that were enriched > 3-fold, but were absent in control sample conducted without anti-flag antibody.

Genome-wide maps of O-GlcNAc-Oct4 binding regions in ZHBTc4 F-Oct4 mouse embryonic stem cells

Project description:We report that Oct4 is modified by O-GlcNAc in stem cells. To find O-GlcNAc-Oct4 target genes, we ChIPed Oct4 with Flag(Oct4) antibody and then O-GlcNAc modified proteins are enriched by sWGA beads (succinylated wheat germ agglutinin (sWGA), which specifically binds O-GlcNAc). Results show that several genes implicated in pluripotency regulation are bound by O-GlcNAc-Oct4 in their gene region. 2 samples examined: Control (ChIP with anti-Flag(Oct4) and then reChIP with IgG), O-GlcNAc-Oct4 (ChIP with anti-Flag (Oct4) and then reChIP with sWGA)

Expression data from Pseudomonas aeruginosa âsbrR and âsbrIR mutants versus wild type

Project description:SbrI and SbrR are an extracytoplasmic function sigma factor and its cognate anti-sigma factor, respectively. To identify the SbrIR regulon, we measured gene expression in wild type PAO1 , PAO1 âsbrR, and PAO1 âsbrIR mutants using microarrays. WT PAO1 pPSV38 (empty vector), PAO1 âsbrR pPSV38, PAO1 âsbrR pSbrR, and PAO1 âsbrIR pPSV38 were grown to mid-log. RNA was extracted and reverse transcribed into cDNA. The cDNA was biotinylated and hybridized to Pseudomonas aeruginosa Affymetrix microarrays.

ONECUT2 Drives Neuroendocrine Prostate Cancer Through Hypoxia Signaling

Project description:To determine the underlying mechanism of ONECUT2 in prostate cancer hypoxia, we conducted a series of RNA-Seq and ChIP-Seq experiments in LNCaP and PC3 cells under normoxia and hypoxia conditions. We did RNA-Seq in LNCaP cells with or without OC2 overexpression and in PC3 cells with or without OC2 knockdown. We used anti-Flag antibody to perform the ChIP-Seq experiment in PC3 cells with Flag and OC2 fusion protein overexpression. We also performed HIF1A ChIP-Seq in AR-negative prostate cancer cell line PC3 under hypoxia condition with or without ONECUT2 or SMAD3 siRNA knockdown. SMAD3 and HIF2A ChIP-Seq were conducted in PC3 cells under hypoxia condition. To confirm the interactions between transcription factors, we also performed ChIP-reChIP-seq. We did the primary ChIP experiment using anti-SMAD3 antibody and then we subjected the ChIPed chromatin by the primary ChIP to reChIP experiments using anti-HIF1A or anti-HIF2A antibody. The reChIPed DNA was submitted to next generation sequencing.

ChIP-seq analysis of FfmA binding in Aspergillus fumigatus

Project description:Two strains were analyzed by ChIP-seq to determine the genomic binding sites for the Aspergillus fumigatus transcription factor FfmA. A wild-type strain (AfS35) was subjected to ChIP-seq analysis using an antibody directed against the wild-type version of the FfmA protein. An strain containing an epitope-tagged version (FLAG-ffmA) of the ffmA gene under control of a doxycycline off (dox off) promoter was also analyzed by ChIP-seq. In this latter case, an anti-FLAG antibody was used. The negative controls in both cases consisted of a ChIP-seq reaction with the respective primary antibody omitted.
