Project description:The CiaRH and LiaFSR two-component regulatory systems in Streptococcus agalactiae (Group B Streptococcus, GBS) are essential mediators of the organism s response to biologically important sources of environmental stress, and positive regulators of GBS virulence. Transcriptional profiling of CiaR mutant GBS and LiaR mutant GBS reveals that LiaR is positively-regulated by CiaR, and the individual mutant transcriptomes share a number of commonly-regulated genes. To determine the GBS response to loss of both of these key regulatory systems, we constructed a GBS mutant strain with non-polar deletions in both ciaR and liaR, and performed transcriptional profiling using DNA microarray analysis, comparing wild-type GBS to CiaR/LiaR double mutant GBS under non-stressed conditions. Two separate RNA samples were extracted for each condition. One flip-dye replicate (2 hybridizations) was obtained for each pair of RNA samples for 4 hybridizations total.

Project description:Streptococcus agalactiae (Group B Streptococcus, GBS) is a leading cause of early-onset neonatal bacterial infection. Evasion of innate immune defenses is critical to neonatal GBS disease pathogenesis. Effectors of the innate immune system such as antimicrobial peptides, as well as numerous antibiotics, target the peptidoglycan layer of the gram positive bacterial cell wall. The intramembrane-sensing histidine kinase class of two-component regulatory systems has recently been identified as important to the gram-positive response to cell wall stress. We identified and characterized the GBS homolog of LiaR, the response regulator component of the LiaFSR system and constructed site-directed, non-polar deletion mutations in the regulator gene liaR. GBS LiaR deletion mutant strains are more susceptible to cell wall active antibiotics (vancomycin and bacitracin) as well as antimicrobial peptides (colistin, nisin and the human cathelicidin LL-37) compared to isogenic wild-type GBS. LiaR mutant GBS are significantly attenuated in mouse models of both GBS sepsis and GBS pneumonia. To determine the genes regulated by LiaR that account for these defects, transcriptional profiling was performed using DNA microarray analysis, comparing wild-type GBS to LiaR mutant GBS under non-stressed conditions. Two separate RNA samples were extracted for each condition. One flip-dye replicate (2 hybridizations) was obtained for each pair of RNA samples for 4 hybridizations total.

Project description:This dataset contains ChIP-seq data of H3K4me3 and Pol III in single cell-derived control and CRISPR/Cas9 induced tRNA gene deletion clones in human cancer cell lines HAP1 and HepG2. In this study, we looked into functional Cas9-induced on-target genomic alteration in our tRNA gene deletion clones, HAP1 t72 and HepG2 t15.

Project description:Purification of mouse mRNAs encoding signal transducer and activator of transcription 3 (Stat3) identified many miRNAs using multiplex miRNA array in RAW264.7 cells. To investigate the miRNAs targeting to mouse Stat3 gene in macrophage cells, we performed a protocol miRIP to affinity purify the miRNAs from an endogenous segment of Stat3 mRNA using nucleic acid hybridization and use multiplex miRNA array to identify the associated miRNAs.

Project description:Trimethylation of histone H3 lysine 4 (H3K4me3) is associated with transcriptional start sites and proposed to regulate transcription initiation. However, redundant functions of the H3K4 SET1/COMPASS methyltransferase complexes complicate elucidation of the specific role of H3K4me3 in transcriptional regulation. Here, by using mouse embryonic stem cells (mESCs) as a model system, we show that acute ablation of shared subunits of the SET1/COMPASS complexes leads to complete loss of all H3K4 methylation. H3K4me3 turnover occurs more rapidly than H3K4me1 and H3K4me2 and is dependent on KDM5 demethylases. Surprisingly, acute loss of H3K4me3 does not have detectable effects on transcriptional initiation but leads to a widespread decrease in transcriptional output, an increase in RNA polymerase II (RNAPII) pausing and slower elongation. Notably, we show that H3K4me3 is required for the recruitment of the Integrator Complex Subunit 11 (INTS11), which is essential for the eviction of paused RNAPII and transcriptional elongation. Thus, our study demonstrates a distinct role for H3K4me3 in transcriptional pause-release and elongation rather than transcriptional initiation.

Project description:Dissection of the physiological interactomes of histone post-translational modifications (hPTMs) is crucial for understanding fundamental epigenetic regulatory pathways. Current peptide- or protein-based histone photoaffinity probes have greatly expanded the ability to probe the epigenetic interactome, but in situ profiling in the context of native cells (live cells without genetic manipulations) remains challenging. Here, we developed a nucleus-targeted histone photoaffinity probe with a modular design that integrates a cell-permeable and nuclear localization peptide modules into an hPTM peptide equipped with a photoreactive moiety for profiling the hPTM-mediated interactome in native cells. This probe not only enables the probing of epigenetic interactomes in hard-to-transfect macrophage RAW264.7 cells, but also offers opportunities to characterize the interactome of newly emerging hPTM, such as lactylation, thus expanding the toolbox for profiling of hPTM-mediated PPIs in live cells.

Project description:To determine gene expression changes during in vitro senescence of MSC we have analyzed differential expression of the corresponding early passage (P2) and senescent passage (PX). There were global changes in the gene expression profile that were reproducible in three independent donor samples. Experiment Overall Design: Mesenchymal Stem Cells (MSC) were isolated from human bone marrow (BM) as described before (Wagner et al., 2005, Exp Hematol, 33, 1402-1416; Wagner et al., Exp Hematol, 34, 536-548). Cells were always replated when grown to confluency. A sample for RNA isolation was taken at every passage until the cells finally became senescent: they became much larger with irregular and flat shape. The nucleus became more circumscribed in phase contrast microscopy. The cytoplasm began to be granular with many inclusions and there was more cell debris. Global gene expression profiles were analyzed to determine molecular changes between corresponding early passage (P2) and senescent passage (PX) in three donor samples. In addition we have analyzed different passages of donor 1 (P2, P3, P4, P5, P6, P7, P8, P10, and P11) to determine changes in the course of cellular aging. Data were median normalized and compared to P2 of the corresponding donor sample.
