Project description:To screen the differentially expressed lncRNAs, we performed lncRNA profiling using ArrayStar Human LncRNA Microarray in 24 new-onset systemic lupus erythematosus (SLE) patients and 12 age- and sex-matched healthy controls (HCs). For the lncRNA microarray screening, total RNA from plasma was isolated from 12 SLE without nephritis, 12 lupus nephritis (LN) and 12 HCs. Four RNA samples were mixed togther as a pool of sample for microarray analysis. Accordingly, there were each three pooled RNA samples from 12 SLE without nephritis, 12 LN and 12 HCs for microarray analysis. Hierarchical clustering showed the plasma levels of lncRNAs and mRNAs differed significantly between 24 new-onset SLE patients and 12 control subjects. With a fold change ≥ 2 and P ≤ 0.05, we identified 1315 significantly differentially expressed lncRNAs (743 lncRNAs up-regulated and 572 lncRNAs down-regulated) and 1363 differentially expressed mRNAs (745 mRNAs up-regulated and 618 mRNAs down-regulated) in plasma of SLE patients compared with control samples.
Project description:Gene expression profile studies have identified an interferon signature in whole blood or mononuclear cell samples from patients with systemic lupus erythematosus. This study was designed to determine whether specific lymphocyte and myeloid subsets freshly isolated from the blood of systemic lupus erythematosus patients demonstrated unique gene expression profiles compared to subsets isolated from healthy controls. Keywords: patient compared to control

Project description:Study of high-density lipoproteins using 6 human plasma samples. The study sought to find small RNA signatures in systemic erythematosus lupus.
Project description:Systemic lupus erythematosus carries increased risk of pregnancy complications. To understand the underlying molecular mechanisms, we characterized the blood transcriptome of lupus patients and healthy controls during pregnancy and postpartum and performed multicolor flow-cytometry in a subset. We also followed healthy women undergoing assisted reproductive technology, allowing for analysis around embryo implantation. A striking and sustained down modulation of two lupus-related signatures, interferon and plasma cells, takes place during healthy pregnancy. These changes appear immediately post embryo implantation and are mirrored in uncomplicated lupus pregnancies. Patients with preeclampsia displayed early upregulation of neutrophil signatures and expansion of immature neutrophils. Lupus pregnancies with fetal complications carried the highest interferon and plasma cell signatures as well as ICOS+ CD4+ T cell counts. Thus, healthy and uncomplicated lupus pregnancies exhibit early and sustained transcriptional modulation of lupus-related signatures, and failure to do so is associated with adverse outcomes.
Project description:To investigate the lncRNAs expression profiling in CD4+ T cells of systemic lupus erythematosus (SLE) patients, we have employed “Agilent Human lncRNA 4*180K microarray” as a discovery platform to identify lncRNAs and mRNAs expression signatures in CD4+ T cells between SLE patients and normal controls. CD4+ T cells were isolated from peripheral blood mononuclear cells (PBMCs) of peripheral blood in SLE patients and normal controls, respectively.
Project description:Systemic lupus erythematosus (SLE), also known simply as lupus, is an autoimmune disease. There is no cure for SLE. The mechanism involves an immune response by autoantibodies against a person's own tissues. However, the mechanism underlying imbalance of autoantibodies is not clear. In this experiment, peripheral blood was obtained from normal healthy donors and systemic lupus erythematosus (SLE) patients. Peripheral blood mononuclear cells (PBMC) were separated by Ficoll separation solution. Samples of four (total eight) donors were pooled and Samples of four (total eight) SLE patients were pooled. The aim was to characterize the mRNA profile of SLE patients compared to healthy donors and find the new target of diagnosis or treatment for SLE.
Project description:In this experiment, the miRNA profile of microvesicles (MV) released from activated or apoptotic (UV-B treated) T-lymphocytes and their cells of origin was analyzed in both samples obtained from normal healthy donors and systemic lupus erythematosus (SLE) patients. Therefore in short, RNA was isolated of activated and apoptotic (UV-B treated) T-Lymphocytes and corresponding MV of normal healthy individuals and systemic lupus erythematosus (SLE) patients. Samples of four donors each were pooled. The aim was to characterize the miRNA profile of MV dependent on different release stimuli and compare their miRNA-profile to their cells of origin.
