RNA-seq for hand-microdissected glomeruli from Immunoglobulin A nephropathy patients

ABSTRACT: We collected glomeruli from biopsy specimens from IgA nephropathy patients with relatively preserved kidney function (eGFR ≥ 60 mL/min/1.73 m2 and urine protein-to-creatinine ratio < 3 g/g) and from normal kidney cortices by hand microdissection and performed RNA-seq. The transcriptomic profiling of IgA nephropathy glomerulus provide insights for intraglomerular pathophysiology of IgAN before reaching profound kidney dysfunction.

Metabolomics of immunoglobulin-producing cells in IgA nephropathy

Project description:IgA nephropathy (IgAN), the most common primary glomerulonephritis, is characterized by deposits of IgA-containing immune complexes in the kidney glomeruli, as first described by Berger and Hinglais in 1968. IgAN is a major cause of end-stage renal disease with its associated cardio-renal morbidity and mortality. Analyses of the IgA deposits revealed that the IgA is exclusively of the IgA1 subclass and that this IgA1 is aberrantly glycosylated, deficient in galactose in some O-glycans (Gd-IgA1). Patients with IgAN have elevated serum levels of Gd-IgA1 bound by anti-glycan autoantibodies in circulating immune complexes (CIC) that are fundamental in driving disease pathology in an autoimmune process. We have recently shown that elevated serum levels of Gd-IgA1 in patients with IgAN predict disease progression. Thus, understanding the mechanisms behind Gd-IgA1 production will improve future treatment options, as there is presently no disease-specific therapy. A total of 24 cell pellets (4 replicates from 6 cell lines) were analyzed by LCMS metabolomics. Immortalized immunoglobulin-producing cell lines were generated from peripheral-blood lymphocytes from patients with IgAN and healthy controls as described in Suzuki, H., Moldoveanu, Z., Hall, S., et al. IgA1-secreting cell lines from patients with IgA nephropathy produce aberrantly glycosylated IgA1. J Clin Invest. 2008, 118, 629-639.

Transcriptomic and proteomic profiling reveal insights of mesangial cell function in patients with IgA Nephropathy

Project description:IgA nephropathy (IgAN) is the most common glomerulonephritis in the world. The disease is characterized by galactose deficient IgA (gd-IgA) in the circulation forming immune complexes. The complexes are deposited in the glomerular mesangium leading to inflammation and loss of renal function, but the pathophysiology of the disease is still not fully understood. Using an integrated global transcriptomic and proteomic profiling approach we investigated the role of the mesangium in the onset and progression of IgAN. Global gene expression was investigated by microarray analysis of the glomerular compartment of renal biopsies from patients with IgAN. The influence of galactose deficient IgA (gd-IgA) on mesangial cells was investigated by proteomic profiling. By utilizing the previous published literature curated glomerular cell type-specific genes, we found that mesangial cells and their positive standard genes play a more dominant role in IgAN comparing to the podocyte standard genes. Additionally, the patient clinical parameters (serum creatinine values and estimated glomerular filtration rate - eGFR) significantly correlate with z-scores derived from expression profile of mesangial cell positive standard genes. 22 common pathways were identified both from in vivo microarray data and in vitro mesangial cell mass spectrometry data and the main part was inflammatory pathways. The correlation between clinical data and mesangial standard genes allows for a better understanding of the onset of IgAN. The genes, proteins and their corresponding pathways identified in this paper give us novel insights into the pathophysiological mechanisms leading to progression of IgAN. RNA from glomerular compartment was extracted and processed for hybridization on Affymetrix microarrays. This dataset is part of the TransQST collection.

IgA Nephropathy Proteome Profiling

Project description:IgA nephropathy (IgAN) is a heterogeneous disease, which poses a series of challenges to accurate diagnosis and personalized therapy. Here, we present a systematic quantitative kidney tissue proteome atlas across 19 tumor-adjacent normal kidney tissues, 12 membranous nephropathy (MN) samples and 59 biopsies from IgAN patients. Consensus sub-clustering of proteome profiles divided IgAN into three subtypes (IgAN-C1, C2 and C3). Compared to IgAN-C2, the IgAN-C1, and C3 subtypes had a different regulating mechanism and exhibited higher levels of complement activation, more severe mitochondrial injury, and more significant extracellular matrix accumulation. Additionally, IgAN-C1 and C3 had worse clinical outcomes than C2 (30% serum creatinine increase as the end point, P<0.01). Overall, the novel proteomic prognostic subtyping of IgAN could help us understand the heterogeneity of IgAN and improve clinical outcomes.

ALTERED MONOCYTE GENE EXPRESSION AND EXPANSION OF CD14+CD16+ SUBSET IN IgA NEPHROPATHY PATIENTS

Project description:The basic defect of IgA nephropathy (IgAN) lies within peripheral blood mononuclear cells rather than local kidney abnormalities. Previously we showed an altered gene expression in monocytes compared to B and T cells isolated from IgAN patients (Kidney Int, 2010), thus our aim here was to study this subset more closely at genome-wide level. total of 35 IgAN patients and 35 healthy blood donors (HBD) were included in this study. Illumina microarray technology was used to evaluate global differences in gene expression between monocytes isolated from IgAN patients and HBD. Bioinformatic analysis was performed with GenomeStudio and Genespring software. The connectivity between genes was evaluated using Ingenuity Pathway Analysis. Aberrantly expressed genes and pathways were then validated on an independent set of patients with RT-PCR western blot and flow cytometric analysis.
