Description
Microglia depletion significantly lowered spine density in young (developing) but not mature adult-born-granule-cells (abGCs) in the olfactory bulb. PLX5622 significantly reduces microglia related gene transcripts. Overall design: We tested mouse olfactory bulb transcription in WT mice versus mice treated with a PLX5622 diet (inducing a near-complete microglia depletion).

Description
The precise makeup of chromatin remodeling complexes is important for determining cell type and cell function. The SWI/SNF chromatin remodeling complex is made up of multiple subunits that can be filled by mutually exclusive proteins. Inclusion or exclusion of these proteins has profound functional consequences, yet we currently understand little about the direct functional relationship between these biochemically distinct forms of remodeling complexes. Here we combine chromatin immunoprecipitation, transcriptome analysis, and transcription factor binding information from the ENCODE project to determine the functional relationship between three biochemically distinct forms of SWI/SNF. We find widespread overlap in transcriptional regulation and the genomic binding of the three ARID (AT-Rich Interacting Domain) subunits of SWI/SNF. Despite the numerous similarities in their transcriptional regulation and the co-factors bound with each ARID we identify several novel interaction modalities. Previous work has found examples of competition or subunit switching at individual loci, and we find this functional relationship is widespread, and in these cases gene expression changes following loss of one ARID depend on the function of another ARID. We also identify a previously unknown cooperative interaction between ARID1B and ARID2 in the repression of a large number of genes. Together these data help untangle the complicated combinatorial relationships between a highly heterogenous chromatin remodeling family. Overall design: We performed depletion of ARID subunits (ARID1A , n=5; ARID1B, n=3, ARID2, n=5) of SWI/SNF using siRNA or a Non-Targeting control (N=6) and performed expression analysis using polyA+ selected RNA and a strand-specific dUTP incorporation library protocol.

Description
Vaccination reduces morbidity and mortality from pneumonia but its effect on the tissue-level response to infection is still poorly understood. We evaluated pneumonia disease progression, acute phase response and lung gene expression profiles in mice inoculated intranasally with virulent gram-positive Streptococcus pneumoniae serotype (ST) 3, with and without prior immunization with pneumococcal polysaccharide ST 3 (PPS3), or co-immunization with PPS3 and with a low dose of lipopolysaccharide (LPS). Pneumonia severity was assessed in the acute phase, 5, 12, 24 and 48 h post-inoculation (p.i.) and the resolution phase of 7 days p.i. Primary PPS3 specific antibody production was upregulated and IgM binding to pneumococci increased in PPS3-immunized mice. Immunizations with PPS3 or PPS3 + LPS decreased bacterial recovery the lung and blood at 24 and 48 h and increased survival. Microarray analysis of whole lung RNA revealed significant changes in the acute phase protein serum amyloid A (SAA) between noninfected and infected mice, which were attenuated by immunization. SAA transcripts were higher in the liver and lungs of infected controls, and SAA protein was elevated in serum, but decreased in PPS3-immunized mice. Thus, during a virulent pneumonia infection, prior immunization with PPS3 in an IgM-dependent manner as well as co-immunization with PPS3 + LPS attenuated pneumonia severity and promoted resolution of infection, concomitant with significant regulation of cytokine gene expression in the lungs, and acute phase proteins in the lungs, liver and serum.

Description
Using gene expression profiling we characterize the global effect of p53 on the TLR5-mediated transcription in MCF7 cells. We found that combined activation of p53 and TLR5 pathways synergistically increases expression of over 200 genes, mostly associated with immunity and inflammation. The synergy was observed in several human cancer cells and primary lymphocytes.

Description
Oligonucleotide and complementary DNA microarrays are being used to subclassify histologically similar tumours, monitor disease progress, and individualize treatment regimens. However, extracting new biological insight from high-throughput genomic studies of human diseases is a challenge, limited by difficulties in recognizing and evaluating relevant biological processes from huge quantities of experimental data. Here we present a structured network knowledge-base approach to analyse genome-wide transcriptional responses in the context of known functional interrelationships among proteins, small molecules and phenotypes. This approach was used to analyse changes in blood leukocyte gene expression patterns in human subjects receiving an inflammatory stimulus (bacterial endotoxin). We explore the known genome-wide interaction network to identify significant functional modules perturbed in response to this stimulus. Our analysis reveals that the human blood leukocyte response to acute systemic inflammation includes the transient dysregulation of leukocyte bioenergetics and modulation of translational machinery. These findings provide insight into the regulation of global leukocyte activities as they relate to innate immune system tolerance and increased susceptibility to infection in humans.
