Project 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. We used microarrays to analyze the transcriptome of microdissected renal biopsies from patients with lupus nephritis (LN) RNA from glomeruli and tubulointerstitial compartments was extracted and processed for hybridization on Affymetrix microarrays.

Project description:The purpose of the experiment was to compare the transcriptional profile of lupus nephritis kidney tissue at a first flare and expression at a repeated lupus nephritis episode. All samples were laser microdissected into glomerular and tubular compartments and samples were ran in different cartridges. Fourteen lupus nephritis patients and ten normal controls (7 for glomeruli) FFPE samples were laser microdissected and then ran into 5 cartridges for glomeruli and 5 cartridges for tubulointerstitium. This dataset is part of the TransQST collection.

Key nodes in the renal macrophage inflammatory response form the basis for further mechanistic and therapeutic studies. We used microarrays to analyze the renal transcriptome of three different lupus mouse models, at early stage of lupus and during lupus nephritis. RNA from whole kidneys was extracted and processed for hybridization on Affymetrix microarrays.

Project description:To characterize molecular profiles through the development of lupus nephritis and identify risk factors for end organ damage, we carried out gene expression analysis of microdissected kidneys from lupus-prone NZM2328 mice. We identified a continuum of inflammatory processes associated with the progression from acute inflammatory to chronic destructuve disease initiated in the glomeruli and progressing to the tubulointerstitium. We examind male mice and the congenic NZM2328.R27 strain, both of which are resistant to the development of chronic nephritis and end organ damage, as a means to define pathogenic processes.

Project description:We defined the shared and unique features of systemic lupus erythematosus (SLE) nephritis in 2 mouse models of proliferative renal disease. We identified shared inflammatory mechanisms of SLE nephritis that can be therapeutically targeted. Some common mechanisms are shared with non-immune-mediated renal diseases, suggesting that new strategies to prevent tissue hypoxia and remodeling may be useful in SLE nephritis.

Project description:Transcriptome analysis of RNA samples from glomeruli with and without functional ER⍺ duringnNephrotoxic serum-induced nephritis. There is sex bias in SLE and lupus nephritis with a 9:1 women to men ratio. Timecourse microarray analysis of glomeruli isolated from kidneys during nephrotoxic serum-induced nephritis (NTN) reveled altered expression of genes related to lipid metabolism in WT females compared to ER⍺KO females.
