Description
Nephritis (LN) is a serious manifestation of SLE. Therapeutic studies in mouse LN models do not always predict outcomes of human therapeutic trials, raising concerns about the human relevance of these models. In this study we used an unbiased transcriptional network approach to define similarities and differences between three lupus models and human LN. Affymetrix-based expression profiles were analyzed using Genomatix Bibliosphere software and transcriptional networks were compared using the Tool for Approximate LargE graph matching (TALE). The 20 network hubs (nodes) shared between all three models and human LN reflect key pathologic processes, namely immune cell infiltration/activation, macrophage/dendritic cell activation, endothelial cell activation/injury and tissue remodeling/fibrosis. Each model also shares unique features with human LN. Pathway analysis of the TALE nodes highlighted macrophage/DC activation as a cross-species shared feature. To distinguish which genes and activation pathways might derive from mononuclear phagocytes in the human kidneys the gene expression profile of isolated NZB/W renal mononuclear cells was compared with human LN kidney profiles. Network analysis of the shared signature highlighted NFkappaB1 and PPARgamma as major hubs in the tubulointerstitial and glomerular networks respectively. Key nodes in the renal macrophage inflammatory response form the basis for further mechanistic and therapeutic studies.

Description
Gene expression profiles of 75 tissue samples were analyzed representing the stepwise carcinogenic process from pre-neoplastic lesions (cirrhosis and dysplasia) to HCC, including four neoplastic stages (very early HCC to metastatic tumors) from patients with HCV infection. Gene signatures that accurately reflect the pathological progression of disease at each stage were identified and potential molecular markers for early diagnosis uncovered. Pathway analysis revealed dysregulation of the Notch and Toll-like receptor pathways in cirrhosis, followed by deregulation of several components of the Jak/STAT pathway in early carcinogenesis, then up-regulation of genes involved in DNA replication and repair and cell cycle in late cancerous stages.

Description
Males are 50% more likely to develop end stage kidney failure compared to women. In this study we wanted to find out the molecular mechanism responsible for this increased risk. We collected kidney samples from patients with and without kidney disease and performed a comprehensive gene expression analysis in healthy and diseased male and female kidneys.

Description
A goal of this project is to evaluate the integrin mRNA expression in human neural stem/progenitor cells (hNSPC) using high-throughput sequencing technologies. We found high levels of mRNA expression for the ß1, a7, a3, a6, ß5, aV, a5, and a9 integrins. This suggests that hNSPCs may express integrin receptors that can bind fibrinogen and laminin proteins. Overall design: mRNA profiles of hNSPCs from three different passages (12, 15, and 17) were generated by deep sequencing using Illumina HiSeq 2500.

Description
Successful host defense against pathogens requires innate immune recognition of the correct pathogen associated molecular patterns (PAMPs) by pathogen recognition receptors (PRRs) to trigger the appropriate gene program tailored to the pathogen. While many PRR pathways have been shown to contribute to the innate immune response to specific pathogens, the relative importance of each pathway for the complete transcriptional program elicited has not been examined in detail. Herein, we used RNA-sequencing with wildtype and mutant macrophages to delineate the innate immune pathways responsible for the early transcriptional response to Staphylococcus aureus, a ubiquitous microorganism that can activate a wide variety of PRRs. Unexpectedly, only two PRR pathways – the Toll-like receptor (TLR) and Stimulator of Interferon Gene (STING) pathways - were identified as dominant regulators of approximately 95% of the genes that were potently induced within the first four hours of macrophage infection with live S. aureus. TLR signaling predominantly activated an inflammatory program, STING signaling activated an antiviral/type I interferon response, and both pathways contributed to a program linking innate and adaptive immunity. Only a small number of genes were induced in the absence of TLR or STING signaling, and these genes possessed a strong hypoxia signature. STING pathway activation required live S. aureus and was largely dependent on the DNA sensor cyclic guanosine-adenosine synthase (cGAS) recognition of S. aureus DNA. Interestingly, using a cutaneous infection model, we found that the TLR and STING pathways played opposite roles in host defense to S. aureus, with TLR signaling being required for protective interleukin (IL)-1? and neutrophil recruitment and STING signaling having an opposite effect. These results provide novel insights into the complex interplay of innate immune signaling pathways triggered byS. aureus and uncover opposing roles of TLR and STING in cutaneous host defense to S. aureus. Overall design: Files are labeled according to the figures in which they were used. Note, that many data files were used in multiple figures or figure panels. Files are labeled by genotype of macrophages (WT=wildtype; KO= StingGt/Gt; DKO=MyD88-/-TRIF-/-) and whether the macrophages were treated with live (Live) or heat killed (HK) or uninfected (zero hour). Labeling of time points is in the order of "minutes_replicate #." For example, "WT_HK_30_2" indicates that this is wild type mouse macrophages stimulated with heat killed bacteria at the 30-minute time point and is replicate number 2. Reads were converted into RPKM, and the RPKM for all replicates listed for a given time point were averaged to obtain the average RPKM that was used for figures and analyses. For samples listed as contributing to either figure 3 or supplemental figure 2, the replicates that do NOT end in either KO_analysis nor DKO analysis were used to determine induced genes in wild type macrophages. In contrast, the replicates that end in KO_analysis or DKO_analysis were used to determine dependence on either STING signaling or MyD88/TRIF signaling, respectively. If a replicate was used in the STING or MyD88/TRIF dependence analysis for both live and heat-killed S. aureus, "live_and_hk" was added after the dependence analysis it contributed to. Some 0h samples were used in both live and heat-killed analyses.
