Micro RNA expression profiling using NanoString technology from IgA Nephropathy patients from Indian cohort.

Project description:The current study makes use of NanoString targeted technology to profile urinary exosomal miRNAs from IgA nephropathy affected patients and corresponding healthy controls. Circulatory biomarkers were detected for IgA nephropathy from Indian cohort which can be made used for the diagnostic therapy. 14 miRNAs were detected to be related to the disregulation in miRNome of IgA nephropathy patients using lasso feature selection method, out of which multiple miRNAs like hsa.mir.146b.3p, hsa.mir.599 and many more was resulted with high AUROC values >=0.9 efficient in differentiating between healthy controls and IgA nephropathy condition. These markers can be use further in the diagnosis and treatment of IgAN.

Role of IgG autoantibodies in the pathogenesis of IgA nephropathy assessed in a passive mouse model

Project description:IgA nephropathy (IgAN), the most common primary glomerulonephritis worldwide, is characterized by IgA1-containing glomerular immunodeposits. These immunodeposits are thought to originate from the circulating immune complexes consisting of aberrantly glycosylated IgA1 (galactose-deficient IgA1; Gd-IgA1) bound by IgG autoantibodies. This hypothesis is supported by the findings that renal immunodeposits of IgA nephropathy patients are enriched for IgG autoantibodies specific for galactose-deficient IgA1 (Rizk et al., J. Am. Soc. Nephrol. 30(10), 2017-2026, 2019). However, experimental proof is needed. This study provides in vivo data in mice that support the pathogenic role of IgG autoantibodies in IgAN.

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.
