Project description:Genome-wide alternative splice analysis of RNA from lupus and its severe form lupus nephritis We aimed to explore the genome-wide peripheral blood transcriptome of lupus (SLE) and its severe form lupus nephritis (LN) cases compared to healthy subjects (HC) using high density Affymetrix Human Exon1.0.ST arrays. Analysis revealed 15 splice variants that are differentially expressed between SLE/HC and 99 variants between LN/HC (pâ¤0.05,SI>orâ¤0.5,Benjamin Hochberg-False discovery rate correction). Comparison between LN/SLE revealed 7 variants that are differentially expressed with pâ¤0.05,SI>0.5,Benjamin Hochberg-FDR correction. Pathway analysis of differentially spliced genes revealed 11 significant pathways in SLE and 12 in LN (p<0.05). Analysis of peripheral blood transcriptome revealed signature causative genes that are alternatively spliced, signifying their clinical relevance in the pathophysiology of disease. The extent of differential splicing was found to be higher in LN than in SLE, signifying the need for further in-depth research in the same domain. Present study is the first to reveal the significance of alternative variants in susceptibility to SLE and LN. We analyzed blood from 11 female subjects (5 lupus, 3 lupus nephritis and 3 healthy control) using the Affymetrix Human Exon 1.0 ST platform. Array data was processed by Alt Analyze and Genespring software. No techinical replicates were performed. One of the outiler sample (HC2) was excluded from further analysis.

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 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:Neutrophyl Extracellular Traps (NETs) accumulated in serum of patients with Lupus Nephritis for defective removal by DNAse. Among a complex protein panel (overall 802) two clusters of 16 and 13 proteins were more expressed by LN and SLE NETs respectively; oxidized aenolase and annexin A1 were main components of the first series in LN. NETs may represent a source of modified intracellular antigens for autoimmunity in LN.

Project description:<p>Lupus nephritis (LN) is a severe manifestation of systemic lupus erythematosus (SLE) and it occurs at a much higher rate in patients that are not of European descent. The purpose of this study is to identify genetic variants contributing to the risk of LN in a multi-ethnic cohort of SLE patients. We used a comprehensive genome-wide screen and 1244 SLE patients from 5 different ethnic groups. In genome-wide gene-based and candidate SNP analyses, we found distinct genes and pathways, and established risk SNPs associated with lupus nephritis for each ethnic group. This study represents progress in elucidating the genetic underpinnings driving LN among SLE patients of different ethnic groups.</p>

Project description:The goal is to discover novel circulating immune complexes (ICx) in the serum of Lupus Nephritis (LN) as potential biomarkers. Protein A/G magnetic beads or C1q-coated plates were used to capture ICx in the serum of LN, followed by the identification of immunoglobulin-binding proteins using liquid chromatography and tandem mass spectrometry (LC-MS/MS). Six related genomic-level databases were used for selecting potential biomarkers, following ELISA validation with independent samples.
