Abstract
IgA nephropathy is the most common primary glomerulonephritis worldwide and can progress to end-stage kidney disease (ESKD). The current "gold standard" for diagnosis is kidney biopsy, which is invasive and associated with morbidity. miRNAs are small, non-coding endogenous RNA that may serve as non-invasive biomarkers, and that are found in urinary exosomes. Thus far, there is a paucity of studies of the miRNA profile for the diagnosis of IgA nephropathy. Hence, we aimed to study the urinary exosomal miRNA signature of Indian patients with IgA nephropathy. Fifty biopsy-proven IgA nephropathy patients, 50 healthy controls and 25 patients with ESKD (IgA nephropathy) were recruited over 2 years (2020-2022). Urinary exosomes were isolated from which miRNA was extracted . Analysis of urinary exosomal miRNA was done using the digital multiplexed nCounter® human v3 miRNA Expression Assay which contains 799 unique miRNA barcodes. Candidate miRNAs were identified using Lasso regression and consensus clustering. The mean age of IgA nephropathy patients was 36.32 ± 3.067 years, mean creatinine was 2.26 ± 0.318 mg/dl and mean proteinuria was 2.69 ± 0.64 g/day. Compared to healthy controls, the majority (N = 150) of miRNAs were significantly downregulated. Five candidate miRNAs (hsa.miR.146b.3p, hsa.miR.599, hsa.miR.4532, hsa.miR.664b.5p and hsa.miR.221.5p) were able to differentiate between IgA nephropathy cases and controls (AUC > 0.90); the presence of all 5 was associated with 100% specificity and sensitivity for diagnosing IgA nephropathy cases. This study of Indian patients identified that there was a significant difference in the urinary exosomal miRNA profile between IgA nephropathy cases and healthy controls, suggesting that miRNAs may be valuable in the non-invasive diagnosis of IgA nephropathy.

Noncoding RNAs associated with IgA nephropathy. J Nephrol 2022; 36:911-923. [PMID: 36495425 DOI: 10.1007/s40620-022-01498-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Accepted: 10/10/2022] [Indexed: 12/14/2022]
Abstract
IgA nephropathy (IgAN) is one of the most common glomerulonephritides. The disease is characterized by haematuria, proteinuria, deposition of galactose-deficient IgA1 in the glomerular mesangium and mesangial hypercellularity, further leading to extracellular matrix expansion. Kidney biopsy is the gold standard for IgAN diagnosis. Due to the invasiveness of renal biopsy, there is an unmet need for noninvasive biomarkers to diagnose and estimate the severity of IgAN. Understanding the role of RNA molecules as genetic markers to target diseases may allow developing therapeutic and diagnostic markers. In this review we have focused on intrarenal, extrarenal and extracellular noncoding RNAs involved in the progression of IgAN. This narrative review summarizes the pathogenesis of IgAN along with the correlation of noncoding RNA molecules such as microRNAs, small interfering RNAs, circular RNAs and long non-coding RNAs that play an important role in regulating gene expression, and that represent another type of regulation affecting the expression of specific glycosyltranferases, a key element contributing to the development of IgAN.

Abstract
Background: Urinary microRNA-21 (miR-21) has been reported to correlate with the histologic lesions of IgA nephropathy (IgAN). We investigated whether urinary or circulating miR-21 could serve as a biomarker for detecting the renal progression of IgAN.Methods: Forty patients with biopsy-proven IgAN were enrolled in this study. Serum and urinary sediment miRs were extracted, and the expression of miR-21 was quantified by real-time quantitative polymerase chain reaction. Renal progression was defined as end-stage renal disease, a sustained doubling of serum creatinine, or a 50% decrease in estimated glomerular filtration rate (eGFR) from baseline.Results: Six patients experienced renal progression during the follow-up period. The baseline eGFR was lower in the progression group (49±11 mL/min/1.73 m2 vs. 90±23 mL/min/1.73 m2, p<0.05) than in the non-progression group. The level of circulating miR-21 on kidney biopsy was higher in the progression group than in the non-progression group (40.0±0.6 vs. 38.2±1.1 ΔCt value of miR-21, p<0.01), whereas there was no significant difference in urinary miR-21 (38.1±2.1 vs. 37.8±1.4 ΔCt value of miR-21, p=0.687) between the two groups. Receiver operating characteristic curve analysis demonstrated that circulating miR-21 had good discriminative power for diagnosing renal progression of IgAN, with an area under the curve of 0.975.Conclusions: The level of circulating miR-21 was higher in the progression group than in the non-progression group at the time of kidney biopsy. Therefore, circulating miR-21 could be a surrogate marker of renal progression in patients with IgAN.

Identification of key candidate genes for IgA nephropathy using machine learning and statistics based bioinformatics models. Sci Rep 2022; 12:13963. [PMID: 35978028 PMCID: PMC9385868 DOI: 10.1038/s41598-022-18273-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 08/08/2022] [Indexed: 11/08/2022] Open
Abstract
Immunoglobulin-A-nephropathy (IgAN) is a kidney disease caused by the accumulation of IgAN deposits in the kidneys, which causes inflammation and damage to the kidney tissues. Various bioinformatics analysis-based approaches are widely used to predict novel candidate genes and pathways associated with IgAN. However, there is still some scope to clearly explore the molecular mechanisms and causes of IgAN development and progression. Therefore, the present study aimed to identify key candidate genes for IgAN using machine learning (ML) and statistics-based bioinformatics models. First, differentially expressed genes (DEGs) were identified using limma, and then enrichment analysis was performed on DEGs using DAVID. Protein-protein interaction (PPI) was constructed using STRING and Cytoscape was used to determine hub genes based on connectivity and hub modules based on MCODE scores and their associated genes from DEGs. Furthermore, ML-based algorithms, namely support vector machine (SVM), least absolute shrinkage and selection operator (LASSO), and partial least square discriminant analysis (PLS-DA) were applied to identify the discriminative genes of IgAN from DEGs. Finally, the key candidate genes (FOS, JUN, EGR1, FOSB, and DUSP1) were identified as overlapping genes among the selected hub genes, hub module genes, and discriminative genes from SVM, LASSO, and PLS-DA, respectively which can be used for the diagnosis and treatment of IgAN.

Abstract
MicroRNAs (miRNAs) participate in the regulation of various important biological processes by regulating the expression of various genes at the post-transcriptional level. Podocytopathies are a series of renal diseases in which direct or indirect damage of podocytes results in proteinuria or nephrotic syndrome. Despite decades of research, the exact pathogenesis of podocytopathies remains incompletely understood and effective therapies are still lacking. An increasing body of evidence has revealed a critical role of miRNAs dysregulation in the onset and progression of podocytopathies. Moreover, several lines of research aimed at improving common podocytopathies diagnostic tools and avoiding invasive kidney biopsies have also identified circulating and urine miRNAs as possible diagnostic and prognostic biomarkers for podocytopathies. The present review mainly aims to provide an updated overview of the recent achievements in research on the potential applicability of miRNAs involved in renal disorders related to podocyte dysfunction by laying particular emphasis on focal segmental glomerulosclerosis (FSGS), minimal change disease (MCD), membranous nephropathy (MN), diabetic kidney disease (DKD) and IgA nephropathy (IgAN). Further investigation into these dysregulated miRNAs will not only generate novel insights into the mechanisms of podocytopathies, but also might yield novel strategies for the diagnosis and therapy of this disease.

Abstract
Kidney disease is a multifactorial problem, with a growing prevalence and an increasing global burden. With the latest worldwide data suggesting that chronic kidney disease (CKD) is the 12th leading cause of death, it is no surprise that CKD remains a public health problem that requires urgent attention. Multiple factors contribute to kidney disease, each with its own pathophysiology and pathogenesis. Furthermore, microRNAs (miRNAs) have been linked to several types of kidney diseases. As dysregulation of miRNAs is often seen in some diseases, there is potential in the exploitation of this for therapeutic applications. In addition, uptake of interference RNA has been shown to be rapid in kidneys making them a good candidate for RNA therapy. The latest advancements in RNA therapy and lipid-based nanocarriers have enhanced the effectiveness and efficiency of RNA-related drugs, thereby making RNA therapy a viable treatment option for renal disease. This is especially useful for renal diseases, for which a suitable treatment is not yet available. Moreover, the high adaptability of RNA therapy combined with the low risk of lipid-based nanocarriers make for an attractive treatment choice. Currently, there are only a small number of RNA-based drugs related to renal parenchymal disease, most of which are in different stages of clinical trials. We propose the use of miRNAs or short interfering RNAs coupled with a lipid-based nanocarrier as a delivery vehicle for managing renal disease.

The increased miRNA-150-5p expression of the tonsil tissue in patients with IgA nephropathy may be related to the pathogenesis of disease. Int Immunopharmacol 2021; 100:108124. [PMID: 34600394 DOI: 10.1016/j.intimp.2021.108124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Revised: 08/28/2021] [Accepted: 08/31/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND The microRNA (miRNA) expression of the tonsil tissues in patients with immunoglobulin A (IgA) nephropathy (IgAN) has not been reported in the literature. METHODS In this study, the expression of nine miRNAs was measured in the tonsil tissues of patients with IgAN, including miRNA-21-5p, miRNA-29a-3p, miRNA-34a-5p, miRNA-146a-5p, miRNA-146b-5p, miRNA-148b-3p, miRNA-150-5p, miRNA-155-5p, and miRNA-181a-5p. Forty patients with proved primary IgA nephropathy were enrolled in our study, 20 IgAN patients with gross hematuria, which induced by tonsillitis (GH-IgAN group) and 20 IgAN patients without gross hematuria in the history (non-GH-IgAN group). Another 20 patients recruited as the control group (CT group) were chronic tonsillitis without kidney disease. RESULTS Compared to the CT group, the expression level of miRNA-150-5p in the tonsils was significantly upregulated in the GH-IgAN group, but not in the non-GH-IgAN group (P = 0.031 and P = 0.122, respectively). A correlation analysis was performed between the expression of miRNAs in the tonsils and the clinical data of IgAN patients. The results showed that in the GH-IgAN group, the miRNA-150 expression was positively correlated with systolic blood pressure (β = 2.36, 95% CI 1.11-3.61, P = 0.0016), diastolic blood pressure (β = 1.02, 95% CI 0.22-1.82, P = 0.0224), uric acid (β = 7.43, 95% CI 1.81-13.04, P = 0.0184), leukocyte count (β = 0.22, 95% CI 0.09-0.35, P = 0039), neutrophil count (β = 0.19, 95% CI 0.06-0.32, P = 0.0096), cholesterol (β = 0.09, 95% CI 0.02-0.16, P = 0.0207) and triglyceride level (β = 0.16, 95% CI 0.10-0.22, P < 0.000). Besides, it was negatively correlated with the estimated glomerular filtration rate (eGFR) (β = -2.06, 95% CI: -3.90 - -0.21, P = 0.0421) in the GH-IgAN group; however, no significant correlation was found in the non-GH-IgAN group. CONCLUSION The present findings suggest that miRNA-150-5p may be important in the pathogenesis of IgAN, especially in mucosal immunity against the disease.

Abstract
IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide. It is considered that the pathogenesis of IgAN involves the ‘multiple hit theory’ and the immune-inflammatory mechanism; however, these theories have certain limitations. The gold standard for diagnosing IgAN is still renal biopsy. Although renal biopsy is accurate, it is traumatic and is associated with some risks and limitations, so there is a need for non-invasive diagnostic methods. According to recent studies, microRNAs (miRNAs) play important roles in the occurrence and development of IgAN; thus, they provide the possibility of the noninvasive diagnosis of IgAN and also have some value in predicting prognosis. This review summarizes the current research status of miRNAs in the occurrence, development, diagnosis, and prognosis of IgAN. We also highlight some interesting and challenging points that require further study.

Abstract
Microparticles are a general term for different types of cell plasma membrane-originated vesicles that are released into the extracellular environment. The paracrine action of these nano-sized vesicles is crucial for intercellular communications through the transfer of diverse lipids, cytosolic proteins, RNA as well as microRNAs. The progression of different diseases influences the composition, occurrence, and functions of these cell-derived particles. Podocyte injury has been shown to have an important role in the pathophysiology of many glomerular diseases including IgA nephropathy (IgAN). This review would focus on the possible potential of podocyte-derived microparticles detected in urine to be used as a diagnostic tool in IgAN.

Abstract
IgA nephropathy (IgAN), the most common form of primary glomerulonephritis, is caused by immune system dysfunction and affects only the kidneys. miRNA was involved in IgAN, in which their roles are still unknown. Herein, we found increased glomerular medulla size, proteinuria, kidney artery resistance, kidney fibrosis and immune complex deposition in 5‐month miR‐25/93/106b cluster knockout (miR‐TKO) mice. In vitro, the inhibition of miR‐25 cluster could promote cell proliferation and increase fibrosis‐related protein and transferrin receptor (TFRC) expression in human renal glomerular mesangial cell (HRMC). Luciferase assay revealed that inhibition of miR‐93/106b cluster could upregulate Ccnd1 expression through direct binding with the 3’UTR of Ccnd1. Conversely, inhibition of Ccnd1 expression prevented miR‐93/106b‐induced effect in HRMC. These findings suggested that miR‐25 cluster played an important role in the progression of IgAN, which provided new insights into the pathogenesis and treatment of IgAN.

Abstract
IgA nephropathy (IgAN) is the most commonly diagnosed primary glomerulonephritis worldwide. It is a slow progressing disease with approximately 30% of cases reaching end-stage kidney disease within 20 years of diagnosis. It is currently only diagnosed by an invasive biopsy and treatment options are limited. However, the current surge in interest in RNA interference is opening up new horizons for the use of this new technology in the field of IgAN management. A greater understanding of the fundamentals of RNA interference offers exciting possibilities both for biomarker discovery and, more importantly, for novel therapeutic approaches to target key pathogenic pathways in IgAN. This review aims to summarise the RNA interference literature in the context of microRNAs and their association with the multifaceted aspects of IgA nephropathy.

Abstract
Human induced pluripotent stem cells (iPSCs) are important source for regenerative medicine. However, the links between pluripotency and oncogenic transformation raise safety issues. To understand the characteristics of iPSC-derived cells at single-cell resolution, we directly reprogrammed two human iPSC lines into cardiomyocytes and collected cells from four time points during cardiac differentiation for single-cell sequencing. We captured 32,365 cells and identified five molecularly distinct clusters that aligned well with our reconstructed differentiation trajectory. We discovered a set of dynamic expression events related to the upregulation of oncogenes and the decreasing expression of tumor suppressor genes during cardiac differentiation, which were similar to the gain-of-function and loss-of-function patterns during oncogenesis. In practice, we characterized the dynamic expression of the TP53 and Yamanaka factor genes (OCT4, SOX2, KLF4 and MYC), which were widely used for human iPSCs lines generation; and revealed the co-occurrence of MYC overexpression and TP53 silencing in some of human iPSC-derived TNNT2+ cardiomyocytes. In summary, our oncogenic expression atlas is valuable for human iPSCs application and the single-cell resolution highlights the clues potentially associated with the carcinogenic risk of human iPSC-derived cells. Summary: The single-cell expression atlas in the cardiomyocytes generated from human iPSCs provide potential carcinogenic information for the clinical application of human iPSC-derived cells.

[PMID: 33500698 PMCID: PMC7818539 DOI: 10.3892/etm.2021.9638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2019] [Accepted: 06/20/2019] [Indexed: 12/02/2022] Open
Abstract
The present study aimed to detect the levels of microRNA (miR)-33a-5p in the renal tissue, serum and urine of patients with primary IgA nephropathy (IgAN), thereby preliminarily exploring the association between the levels of miR-33a-5p and the condition of primary IgAN to provide evidence for the expression of miR-33a-5p in the serum and urine of IgAN patients as a clinical marker. Reverse-transcription quantitative PCR was performed to evaluate the level of miR-33a-5p in IgAN patients according to severity and pathological classification. The results suggested that the levels of miR-33a-5p in the serum, urine and kidney tissues of patients with IgAN were lower than those of the control tissues obtained from cancer patients (0.28±0.25 vs. 1.00±0.45, P<0.05; 0.34±0.28 vs. 1.00±0.53, P<0.05; 0.47±0.27 vs. 1.00±0.38, P<0.05, respectively). Receiver operating characteristic curve analysis suggested that the serum and urine levels of miR-33a-5p may be used as a marker to differentiate renal injury in IgAN patients from healthy individuals. At the same time, according to the estimated glomerular filtration rate (eGFR) and Lee classification of nephropathy, it was determined that with the progression of renal failure and the increase of the pathological grade of kidney tissue, the relative level of miR-33a-5p in kidney tissue also decreased (eGFR <50 ml/min vs. eGFR ≥50 ml/min/1.73 m2 group: 0.38±0.27 vs. 1.00±0.34, P<0.001; Lee grade ≤3 group vs. Lee grade >3: 1.00±0.48 vs. 0.38±0.45, P<0.05). This result suggested that the levels of miR-33a-5p in serum, urine and kidney tissues decreased with the severity of renal injury and the progression of renal failure in patients with IgAN. Hence, miR-33a-5p detected in the serum and urine may be used as a non-invasive biomarker to reflect the progression of renal injury and renal failure in patients with IgAN.

Abstract
BACKGROUND Diabetic nephropathy is one of the most common microvascular complications in patients with diabetes. MicroRNA (miRNA, miR) is closely related to the formation, development and pathophysiology of diabetic nephropathy. We aimed to investigate whether miR-193a-3p could be used as a potential biomarker for the diagnosis of diabetic nephropathy. METHODS Plasma samples were collected from all the participants. TaqMan Low Density Array analysis was employed to obtain the miRNA profiles of plasma samples, and qRT-PCR was used to confirm the result. Receiver operating characteristic curves were employed to evaluate the specificity and sensitivity of miR-193a-3p for predicting diabetic nephropathy. RESULTS The expression of miR-193a-3p and miR-320c was elevated and miR-27a-3p was decreased in diabetic nephropathy patients compared to patients with type 2 diabetes and healthy controls. We found that, in diabetic nephropathy patients, the elevated miR-193a-3p expression had a negative correlation with the level of evaluate glomerular filtration rate, while a positive correlation with the level of proteinuria. We further demonstrated that miR-193a-3p could be employed to distinguish patients with diabetic nephropathy. The Kaplan-Meier analysis showed that the high expression of miR-193a-3p significantly shortened the dialysis-free survival of diabetic nephropathy patients. CONCLUSION In conclusion, miR-193a-3p is involved in diabetic nephropathy pathogenesis and may serve as a potentially novel diagnostic biomarker for diabetic nephropathy.

Abstract
Understanding why certain patients with IgA nephropathy progress to kidney failure while others maintain normal kidney function remains a major unanswered question. To help answer this, we performed miRNome profiling by next generation sequencing of kidney biopsies in order to identify microRNAs specifically associated with the risk of IgA nephropathy progression. Following sequencing and validation in independent cohorts, four microRNAs (-150-5p, -155-5p, -146b-5p, -135a-5p) were found to be differentially expressed in IgA nephropathy progressors compared to non-progressors, and patients with thin membrane nephropathy, lupus nephritis and membranous nephropathy, and correlated with estimated glomerular filtration rate, proteinuria, and the Oxford MEST-C scores (five histological features that are independent predictors of clinical outcome). Each individual microRNA increased the discrimination score of the International IgAN Prediction Tool, although due to the small number of samples the results did not reach statistical significance. miR-150-5p exhibited the largest amplitude of expression between cohorts and displayed the best discrimination between IgA nephropathy progressors and non-progressors by receiver operating curve analysis (AUC: 0.8). However, expression was similarly upregulated in kidneys with established fibrosis and low estimated glomerular filtration rates at the time of biopsy. Consistent with a more generic role in kidney fibrosis, in situ hybridization revealed that miR-150-5p was found in lymphoid infiltrates, and areas of proliferation and fibrosis consistent with the known drivers of progression. Thus, miR-150-5p may be a potential functional mediator of kidney fibrosis that may add value in predicting risk of progression in IgA nephropathy and other kidney diseases.

Abstract
Objective To identify serum microRNAs (miRNAs) as potential non-invasive biomarkers for patients with chronic kidney disease (CKD). Methods We collected serum samples from healthy controls, CKD stage 1 (CKD1), and stage 5 (CKD5) patients with primary glomerulonephritis (GN), screened differentially expressed miRNAs (DEMs) using next-generation sequencing (NGS), and confirmed the sequencing data using quantitative reverse transcriptase polymerase chain reaction (qRT-PCR). Results We identified 20 and 42 DEMs in the CKD1 and CKD5 patients compared with the controls, respectively, and 70 DEMs in the CKD5 compared with the CKD1 patients. The qRT-PCR results showed that miR-483-5p was up-regulated in the CKD1 and CKD5 patients compared with controls (fold change = 2.56 and 18.77, respectively). miR-363-3p was down-regulated in the CKD5 patients compared with the controls and CKD1 patients (fold change = 0.27 and 0.48, respectively). Conclusion We identified a genome-wide serum miRNA expression profile in CKD patients, and serum miR-483-5p and miR-363-3p may act as potential diagnostic biomarkers for CKD.

Abstract
IgA nephropathy (IgAN) is the most common primary glomerular disease. The characteristic pathology involves immune complexes formed by the deposition of IgA1 and underglycosylated IgA1 aggregates in the mesangial area, which may be accompanied by the deposition of IgG and/or IgM and complement components. However, the molecular mechanisms of IgAN remain unclear. In the present study, microarray analysis showed that the expression of microRNA-630 (miR-630) was significantly reduced in palatal tonsils from IgAN patients compared with chronic tonsillitis. Additionally, bioinformatic analysis showed that Toll-like receptor 4 (TLR4) was the predicted target gene of miR-630 and was regulated by miR-630. When miR-630 was overexpressed in palatal tonsil mononuclear cells from IgAN patients, the expression of TLR4 was reduced and the content of IgA1 in the cell culture supernatant was decreased, and the level of galactosylation in the IgA1 hinge region was increased. Moreover, immunohistochemical analysis showed that the expression of TLR4 in IgAN patients was significantly increased. After knocking down the expression of TLR4, both the concentration of IgA1 and the binding force of IgA1 with broad bean lectin were significantly reduced in IgAN. Furthermore, the mechanism study demonstrated that TLR4 might regulate the expression of IL-1β and IL-8 through NF-κB signaling pathway to modulate the concentration of IgA1 and the glycosylation level of IgA1. This interesting finding may offer new insight into the molecular mechanism of IgAN.

Abstract
Peripheral blood mononuclear cells (PBMCs) contribute to the deposition of immunoglobulin A (IgA) and progression of IgA nephropathy (IgAN). This study was performed to identify novel microRNAs (miRNAs/miRs) associated with IgAN. Small RNAs were isolated from PBMCs collected from 10 healthy participants and 10 patients with IgAN; the RNAs were then subjected to high‑throughput small RNA sequencing. The results showed that miRNAs constituted 70.33 and 69.83% of small RNAs in PBMCs from healthy participants and patients with IgAN, respectively. In total, 44 differentially expressed miRNAs were identified, of which 34 were upregulated and 10 were downregulated. Among these differentially expressed miRNAs, most showed novel associations with IgAN, except miR‑148a‑3p, miR‑184 and miR‑200a. Furthermore, Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that the target genes of the differentially expressed miRNAs were primarily enriched in cancer pathways, the PI3K‑Akt signaling pathway and MAPK pathways, all of which control cell proliferation and gene expression. Moreover, miR‑3121‑3p, miR‑203a‑3p and miR‑200a‑3p may regulate core 1 synthase, glycoprotein‑N‑acetylgalactosamine 3‑β‑galactosyltransferase 1 (C1GALT1) expression by binding to its 3' untranslated region. In conclusion, 44 differentially expressed miRNAs were discovered, 41 of which were newly found to be associated with IgAN. The differentially expressed miRNAs may regulate the progression of IgAN by controlling the behavior of PBMCs or deposition of IgA via targeting of signaling pathways or expression of C1GALT1. These findings may provide a basis for further research regarding IgAN diagnosis and therapy.

Abstract
Posttranslational modifications (PTMs) to histones such as lysine crotonylation are classified as epigenetic changes. Lysine crotonylation participates in various cellular processes and occurs in active promoters, directly accelerating transcription. The present study performed a proteomics analysis of crotonylation between healthy controls and patients with immunoglobulin A (IgA) nephropathy using tandem mass spectrometry and high-resolution liquid chromatography. The present results identified 353 crotonylated proteins and 770 modification sites, including 155 upregulated and 198 downregulated crotonylated proteins. In total, seven conserved motifs were identified in the present study. The present bioinformatics analysis results suggested a number of the crotonylated proteins exhibited various subcellular localization patterns, such as in the cytoplasm. Protein domains, including thioredoxin, moesin tail and myosin like IQ motif domains were markedly enriched in crotonylated proteins. Kyoto Encyclopedia of Genes and Genomes and functional enrichment analyses suggested significant enrichment of crotonylated proteins in complement and coagulation cascades, and antigen processing and presentation pathways displaying important relationships with IgA nephropathy. The present results suggested that crotonylation occurred in numerous proteins and may play key regulatory roles in IgA nephropathy.

[PMID: 31557418 PMCID: PMC6815813 DOI: 10.1111/jcmm.14582] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2018] [Revised: 06/19/2019] [Accepted: 07/15/2019] [Indexed: 01/15/2023] Open
Abstract
Peripheral blood mononuclear cells (PBMCs) play important roles in the pathogenesis of IgA nephropathy (IgAN). Our study aimed to provide a deep understanding of IgAN and focused on the dysregulation of hsa‐miR‐590‐3p and its target gene HMGB2 in PBMCs. Three gene expression profile datasets (GSE14795, GSE73953 and GSE25590) were downloaded from the GEO database. The DEGs (differentially expressed genes)‐miRNA network that was associated with IgAN was constructed by Cytoscape, and HMGB2 and hsa‐miR‐590‐3p were selected for further exploration. The dual‐luciferase reporter system was utilized to verify their interaction. Then, the expression levels of HMGB2 and hsa‐miR‐590‐3p in PBMCs were detected by qPCR in another cohort, and the correlation of their expression levels with the clinical pathological manifestations and serum Gd‐IgA1(galactose‐deficient IgA1) levels was also investigated. HMGB2 was identified as the target gene of hsa‐miR‐590‐3p. Furtherly, the elderly patients had higher HMGB2 expression levels than the expression levels of the younger patients. As the serum creatinine, serum BUN levels increased, the expression of HMGB2 decreased; Besides, the HMGB2 expression was positively correlated with serum complement 3(C3) levels, and it also had a negative correlation with the diastolic blood pressure, but not reach statistical significance. What is more, both hsa‐miR‐590‐3p and HMGB2 expression had a slight correlation tendency with serum Gd‐IgA1 levels in the whole population. In conclusion, HMGB2, the target gene of hsa‐miR‐590‐3p, was identified to correlate with the severity of IgAN, and this provides more clues for the pathogenesis of IgAN.

Association between histopathological changes and expression of selected microRNAs in skin of adult patients with IgA vasculitis. Histopathology 2019; 75:683-693. [PMID: 31136006 DOI: 10.1111/his.13927] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Accepted: 05/25/2019] [Indexed: 01/06/2023]
Abstract
AIMS IgA vasculitis (IgAV) is a common small-vessel systemic vasculitisthat is histologically characterised by granulocyte infiltration and IgA deposition in vessel walls. Information on microRNA (miRNA) involvement inIgAVis limited. The aim of this study was to analyse the association between histopathological changes and expression profiles of 14 miRNAs in the affected skin of 70 adult patients with IgAV. METHODS AND RESULTS miRNA expression analysis was performed by quantitative real-time polymerase chain reaction and evaluation of histopathological changes by light and immunofluorescence microscopy on formalin-fixed paraffin-embedded skin excision samples. In IgAV-affected skin, granulocyte infiltration was significantly associated with vessel fibrinoid necrosis. Of the analysed miRNAs, four showed two-fold increased expression (let-7d, let-7f, miR-21-5p, and miR-203-3p), five showed five-fold increased expression (let-7b, miR-17-5p, miR-155-5p, miR-423-5p, and miR-451a), and threeshowed 15-fold increased expression (let-7a, miR-21-3p, miR-223-3p), as compared with controls (all P < 0.001). miR-146a-5p and miR-148b-3p showed three-fold decreased expression (P = 0.981 and P < 0.001). The expression of miR-223-3p also showed a significant positive association with granulocyte infiltration and fibrinoid necrosis. CONCLUSIONS Altered miRNA expression, especially of miRNA-223-3p, may be associated with the skin inflammatory state in IgAV. The majority of aberrantly expressed miRNAs in IgAV-affected skin are known to influence the nuclear factor-κB signalling pathway, which is crucial for activation of key proinflammatory genes, including those encoding tumour necrosis factor-α, interleukin (IL)-6, and IL-8. Furthermore, miR-146a-5p and miR-148b-3p, which are negative regulators of inflammatory gene expression, showed decreased expression and could contribute to the exaggerated inflammation. Further investigation of miRNA expression in the affected tissues could improve our knowledge of IgAV pathogenesis, and possibly help to identify novel biomarkers in body fluids.

BMC Nephrol 2019; 20:336. [PMID: 31455266 PMCID: PMC6712721 DOI: 10.1186/s12882-019-1512-x] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Accepted: 08/02/2019] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Though the roles of microRNAs (miRNAs) in renal diseases have been extensively investigated, a thorough screening and comparison of miRNAs among different types of chronic kidney disease (CKD) has never been performed. METHODS The intrarenal miRNAs were profiled from fresh kidney tissues of patients with biopsy-proven minimal change disease (MCD), focal segmental glomerular sclerosis (FSGS) and diabetic nephropathy (DN) by using microarray. Commonly dysregulated miRNAs were validated by real-time PCR using paraffin-embedded renal tissues from all three types of CKD patients as well as mouse unilateral ureteral obstruction (UUO) model. Two novel miRNAs were selected and annotations of their target genes were performed using GO and KEGG pathway enrichment analysis. Biological functions of three two candidate miRNAs were explored in TGF-β1-induced cell model using human kidney proximal tubular cells (HK-2). RESULTS The kidney biopsy samples of three disease types represent different levels of damage and fibrosis, which were the mildest in MCD, moderate in FSGS, and the most severe in DN. 116 miRNAs were identified to be commonly dysregulated, including 40 up-regulated and 76 down-regulated in CKD tissues as compared with healthy donor kidney biopsy tissues. Two novel miRNAs, hsa-miR-3607-3p and hsa-miR-4709-3p, were verified as consistently differentially expressed among all three types of patient samples as well as in mouse model. In vitro, hsa-miR-3607-3p was repressed while hsa-miR-4709-3p was induced by TGF-β1 treatment. Inhibition of hsa-miR-3607-3p or overexpression of hsa-miR-4709-3p promoted TGF-β1-induced migration and F-actin assembling in HK-2 cells, which are characteristics of epithelial-mesenchymal transition (EMT). Further study identified that ITGB8 and CALM3 were the bona fide target genes of hsa-miR-3607-3p and hsa-miR-4709-3p respectively. CONCLUSIONS The present identify a unique miRNAs profile that probably relates to the common fibrosis process of CKD. Results of our study suggest that hsa-miR-3607-3p and hsa-miR-4709-3p may represent as promising therapeutic targets against kidney fibrosis.

Glomerular Hematuria: Cause or Consequence of Renal Inflammation? Int J Mol Sci 2019; 20:ijms20092205.

Abstract
Glomerular hematuria is a cardinal symptom of renal disease. Glomerular hematuria may be classified as microhematuria or macrohematuria according to the number of red blood cells in urine. Recent evidence suggests a pathological role of persistent glomerular microhematuria in the progression of renal disease. Moreover, gross hematuria, or macrohematuria, promotes acute kidney injury (AKI), with subsequent impairment of renal function in a high proportion of patients. In this pathological context, hemoglobin, heme, or iron released from red blood cells in the urinary space may cause direct tubular cell injury, oxidative stress, pro-inflammatory cytokine production, and further monocyte/macrophage recruitment. The aim of this manuscript is to review the role of glomerular hematuria in kidney injury, the role of inflammation as cause and consequence of glomerular hematuria, and to discuss novel therapies to combat hematuria.

Abstract
Alport syndrome (AS) is an inherited progressive disease caused by mutations in genes encoding for the α3, α4 and α5 chains, which are an essential component of type IV collagen and are required for formation of the glomerular basement membrane. However, the underlying etiology of AS remains largely unknown, and the aim of the present study was to examine the genetic mechanisms in AS. Induced pluripotent stem cells (iPSCs) were generated from renal tubular cells. The Illumina HiSeq™ 2000 system and iTRAQ‑coupled 2D liquid chromatography‑tandem mass spectrometry were used to generate the sequences of microRNAs (miRNAs), transcripts and proteins from AS‑iPSCs. Integration of miRNA, transcript and protein expression data was used to construct regulatory networks and identify specific miRNA targets amongst the transcripts and proteins. Relative quantitative proteomics using iTRAQ technology revealed 383 differentially abundant proteins, and high‑throughput sequencing identified 155 differentially expressed miRNAs and 1,168 differentially expressed transcripts. Potential miRNA targets were predicted using miRanda, TargetScan and Pictar. All target proteins and transcripts were subjected to network analysis with miRNAs. Gene ontology analysis of the miRNAs and their targets revealed functional information on the iPSCs, including biological process and cell signaling. Kyoto Encyclopedia of Genes and Genomes pathways analysis revealed that the transcripts and proteins were primarily enriched in metabolic and cell adhesion molecule pathways. In addition, the network maps identified hsa‑miRNA (miR)‑4775 as a prominent miRNA that was associated with a number of targets. Similarly, the prominent ELV‑like protein 1‑A and epidermal growth factor receptor (EGFR)‑associated transcripts were identified. Reverse transcription‑quantitative polymerase chain reaction analysis was used to confirm the upregulation of hsa‑miR‑4775 and EGFR. The integrated approach used in the present study provided a comprehensive molecular characterization of AS. The results may also further understanding of the genetic pathogenesis of AS and facilitate the identification of candidate biomarkers for AS.

Abstract
Since their discovery in 1993, numerous microRNAs (miRNAs) have been identified in humans and other eukaryotic organisms, and their role as key regulators of gene expression is still being elucidated. It is now known that miRNAs not only play a central role in the processes that ensure normal development and physiology, but they are often dysregulated in various diseases. In this review, we present an overview of the role of miRNAs in normal renal development and physiology, in maladaptive renal repair after injury, and in the pathogenesis of renal parenchymal diseases. In addition, we describe methods used for their detection and their potential as therapeutic targets. Continued research on renal miRNAs will undoubtedly improve our understanding of diseases affecting the kidneys and may also lead to new therapeutic agents.

Abstract
IgA nephropathy (IgAN) is the most common cause of primary glomerulonephritis worldwide. Up to 30% of cases develop the progressive form of the disease, eventually requiring renal replacement therapy. Diagnosis and risk stratification relies on an invasive kidney biopsy and management options are limited, with recurrence following renal transplantation being common. Thus the quest to understand the pathophysiology of IgAN has been one of great importance. MicroRNAs (miRs) are short nucleotides that suppress gene expression by hybridizing to the 3' untranslated region of messenger RNA (mRNAs), promoting mRNA degradation or disrupting translation. First discovered in 1993, miRs have since been implicated in a number of chronic conditions, including cancer, heart disease and kidney disease. The mounting interest in the field of miRs has led to fascinating developments in the field of nephrology, ranging from their roles as biomarkers for disease to the development of miR antagonists as avenues for treatment. The translational potential for miRs in IgAN is thus well grounded and may represent a paradigm shift in current approaches to the disease. This review aims to summarize the literature with regard to miRs and their roles in IgAN.

Abstract
Multiple genetic and environmental factors together contribute to the risk of IgA nephropathy (IgAN). MPHOSPH6 play an important role in the recruitment of the exosome to the pre-rRNA. However, to date, little information is found about the association between MPHOSPH6 polymorphisms and the IgAN risk. In this case-control study, we genotyped five single nucleotide polymorphisms (SNPs) in MPHOSPH6 gene in 416 IgAN cases and 495 controls using Sequenom Mass-ARRAY technology and evaluated their association with IgAN using the χ2 and genetic model analysis. In the allelic model analysis, we determined rs1056654 was associated with a 0.774-fold decrease in the risk of IgAN (95%CI= 0.630-0.952; p = 0.015). In the genetic model analysis, we found that the “C/C” genotype of rs1056675 was associated with an increased risk of IgAN based on the codominant model (OR =1.48; 95% CI=1.03-2.13; p=0.033) and recessive model (OR =1.52; 95% CI=1.11-2.09; p=0.0095). The “G/A-A/A” genotype of rs1056654 was associated with a decreased risk of IgAN based on the dominant model (OR =0.75; 95% CI=0.58-0.98; p=0.032) and log-additvie model (OR =0.78; 95% CI=0.64-0.96; p=0.0188). Our data suggested that gene polymorphisms in the MPHOSPH6 may exert influences IgAN susceptibility in a Chinese Han population.

Abstract
BACKGROUND Immunoglobulin A nephropathy (IgAN) is the most common type of primary glomerulonephritis in the world. Reliable biomarkers are required for the non-invasive diagnosis and monitoring of IgAN. This study aims to investigate the difference in urinary exosomal microRNA (miRNA) expression profiles between patients with IgA nephropathy (IgAN) and healthy controls, which may provide clues to identify novel potential non-invasive miRNA biomarkers for renal diseases. METHODS Urine samples were collected from eighteen healthy controls and eighteen patients with IgAN. Differential centrifugation was performed to isolate exosomes from urine samples. High-throughput sequencing and real-time quantitative polymerase chain reaction (RT-qPCR) were sequentially used to screen and further validate miRNA expression profiles in urinary exosomes of patients with IgAN in two independent cohorts. RESULTS Urinary exosomes were successfully isolated to obtain exosomal miRNAs. MiR-215-5p and miR-378i were significantly upregulated in urinary exosomes of patients with IgAN compared with healthy controls (P<.01), while miR-29c and miR-205-5p were significantly downregulated (P<.05). MiR-215-5p, miR-378i, miR-365b-3p and miR-135b-5p were found to have altered expression in patients with IgAN from validation cohorts, which was consistent with the high-throughput sequencing analysis. CONCLUSION This study suggests that there is a significant difference in urinary exosomal miRNA profiles between patients with IgAN and healthy controls. These exosomal miRNAs, such as miR-29c, miR-146a and miR-205 may potentially serve as novel non-invasive biomarkers for IgAN.

Abstract
The emergence of next generation sequencing (NGS) techniques has made the sequencing of whole genomes, transcriptomes, and epigenomes faster and more readily available than previous methods such as Sanger sequencing, which was developed in the 1970s. It is now 10 years since NGS began to revolutionise biological and medical research. Sequencing of RNA provides insights into up or downregulated gene expression patterns and therefore into molecular disease mechanisms. This can lead to the detection of new biomarkers that can be used as diagnostic tools in risk stratification, or even as new therapeutic targets. In nephrology, NGS plays a role in both basic and experimental research, but also in the clinical setting, whereby the diagnosis of innate genetic diseases such as ciliopathies or genetically moderated acquired diseases such as glomerulopathies has improved. NGS enables precise diagnosis and classification of common diseases of the kidneys and urinary tract, aids in both prognostic and predictive decision-making, and in the avoidance of unnecessary therapies. It also plays a role in the risk stratification of disease recurrence after transplantation. NGS is a robust method; however, the performance of NGS is dependent on the method of tissue storage, the extraction of DNA or RNA, and on the sequencing platform itself, as well as on the bioinformatic analyses performed, integration of clinical data, and comprehensive interpretation of the results. The aim of this article is to review and emphasise the importance of NGS as a tool for this generation of nephrologists.

Selection of urinary sediment miRNAs as specific biomarkers of IgA nephropathy. Sci Rep 2016; 6:23498. [PMID: 27000966 PMCID: PMC4802218 DOI: 10.1038/srep23498] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2016] [Accepted: 03/07/2016] [Indexed: 01/22/2023] Open
Abstract
The miRNAs in urinary sediment are easy to obtain, which provides a new approach to searching for non-invasive biomarkers of IgA nephropathy (IgAN). Compared with normal controls (n = 3), 214 different miRNAs in the urinary sediment of IgAN (n = 9) were found by miRNA chip assay. By quantitative PCR analysis, miR-25-3p, miR-144-3p and miR-486-5p were confirmed to be significantly higher in IgAN (n = 93) than in the normal group (n = 82) or disease control (n = 40). These three miRNAs had good specificity and sensitivity for the diagnosis of IgAN by receiver operating characteristic curve analysis, in which the AUC value of miR-486-5p was the largest at 0.935. Urinary sediment miR-25-3p, miR-144-3p and miR-486-5p were demonstrated to be mainly derived from urinary erythrocytes, which were separated by CD235a magnetic beads. The increased expression of urinary erythrocyte miRNAs in IgAN patients was not associated with those in the blood erythrocytes. In addition, urinary supernatant microvesicles of miR-144-3p and miR-486-5p in the IgAN group were also significantly increased. This study showed that the miR-25-3p, miR-144-3p and miR-486-5p in urinary sediment were mainly derived from urinary erythrocytes, which could be non-invasive candidate biomarkers for IgA nephropathy.

Abstract
BACKGROUND Our previous study showed a set of increased miRNAs in serum or urine from nephrotic syndrome children. In this study, we investigated the renal expression of these miRNAs in nephrotic children and explored their role in pathogenesis and as potential indicators to differentiate subtypes of kidney diseases. METHODS We enrolled 52 children with six different subtypes of nephropathy, and 8 normal kidney tissues were used as controls. RT-qPCR was used to quantify the expression of miR-191, miR-151-3p, miR-150, miR-30a-5p and miR-19b in renal tissues. RESULTS miR-191 and miR-151-3p exhibited significantly higher and lower intrarenal expression in all six subtypes of kidney diseases compared to controls. miR-19b was upregulated in three subtypes, and miR-30a-5p and miR-150 were downregulated in two and four subtypes, respectively. The intrarenal expression of miR-150 was significantly different between minimal change disease (MCD) and some other subtypes. The renal levels of these miRNAs correlated significantly with some renal functions and immune parameters. Bioinformatics showed that some target genes of these miRNAs were associated with immune and renal pathological changes. CONCLUSIONS These five miRNAs may be involved in the pathogenesis of nephropathy in children. miR-150 is a potential typing indictor to differentiate MCD from other nephropathy subtypes.

Abstract
Immunoglobulin A (IgA) nephropathy is the most prevalent form of primary glomerulonephritis that often leads to end-stage kidney failure, thereby representing a major health challenge worldwide. Tremendous effort has been dedicated to the diagnosis, monitoring, and treatment of the disease, and the past several years have witnessed exciting advances that have enriched our understanding of the biology, etiology, and pathology of IgA nephropathy. The disease is characterized by predominant deposition of IgA immune complexes that progressively causes activation of mesangial cells, glomerular inflammation, and ultimately renal injury. Multiple recent independent high-throughput studies in cohorts have identified key susceptibility alleles, such as the major histocompatibility complex loci that are significantly associated with the risk of disease occurrence. Notably, a fraction of these risk loci encode proteins that participate in immune defense against mucosal pathogens, particularly intestinal nematodes, indicating a linkage between IgA-mediated antihelminth immunity and the pathogenesis of IgA nephropathy. The emerging "omics" technology also allows for systemic analysis of urinary and serum samples as a noninvasive procedure for diagnosis and prognosis, as demonstrated by several studies implicating the proteomic signature and microRNA profile as promising diagnostic and prognostic parameters. In the clinic, the current treatment protocol relies on suppression of the renin-angiotensin system to control blood pressure and proteinuria. This review scrutinizes and summarizes recent relevant findings that aim to translate researchers' benchside knowledge of disease initiation and development into patients' bedside diagnosis and therapy.

Abstract
Kidney biopsy is the gold standard procedure for providing diagnostic and prognostic information for patients with glomerular-based diseases, however, the utility of this procedure for assessing longitudinal disease activity is limited. The intense search for noninvasive biomarkers of kidney disease activity and injury is driven in large part by the inherent risks of the kidney biopsy procedure and limited information derived from the morphologic description of biopsy findings. Furthermore, gaps in our understanding of the core intrarenal molecular processes underlying the development and progression of glomerular-based diseases has limited the development of effective targeted therapy. In this review, we discuss the potential utility of molecular analysis of the urine to provide a dynamic window into intrarenal molecular and morphologic responses. We focus on molecular analysis of the urine to identify noninvasive surrogate markers of kidney responses, with the goal of using these biomarkers as more sensitive indicators of progression and tissue-level responses to therapeutic interventions in patients with primary glomerulonephritis.

Abstract
miRNAs are regulators of gene expression in diverse biological and pathological courses in life. Their discovery may be considered one of the most important steps in the story of modern biology. miRNAs are packed within exosomes and released by cells for cellular communications; they are present in bodily fluids. Their study opens the way for understanding the pathogenetic mechanisms of many diseases; furthermore, as potential candidate biomarkers, they can be measured in bodily fluids for non-invasive monitoring of disease outcomes. The present review highlights recent advances in the role of miRNAs in the pathogenesis of primary and secondary glomerulonephritides such as IgA nephropathy, focal segmental glomerular sclerosis, lupus nephritis and diabetic nephropathy. The identification of reciprocal expression of miRNAs and their target genes provides the molecular basis for additional information on the pathogenetic mechanisms of kidney diseases. Finally, recent findings demonstrate that miRNAs can be considered as potential targets for novel drugs.

Abstract
Background. MicroRNAs (miRNAs) have been found in virtually all body fluids and used successfully as biomarkers for various diseases. Evidence indicates that miRNAs have important roles in IgA nephropathy (IgAN), a major cause of renal failure. In this study, we looked for differentially expressed miRNAs in IgAN and further evaluated the correlations between candidate miRNAs and the severity of IgAN. Methods. Microarray and RT-qRCR (real-time quantitative polymerase chain reaction) were sequentially used to screen and further verify miRNA expression profiles in urinary sediments of IgAN patients in two independent cohorts. The screening cohort consisted of 32 urine samples from 18 patients with IgAN, 4 patients with MN (membranous nephropathy), 4 patients with MCD (minimal changes disease) and 6 healthy subjects; the validation cohort consisted of 102 IgAN patients, 41 MN patients, 27 MCD patients and 34 healthy subjects. The renal pathological lesions of patients with IgAN were evaluated according to Lee's grading system and Oxford classification. Results. At the screening phase, significance analysis of microarrays analysis showed that no miRNA was differentially expressed in the IgAN group compared to all control groups. But IgAN grade I-II and III subgroups (according to Lee's grading system) shared dysregulation of two miRNAs (miR-3613-3p and miR-4668-5p). At the validation phase, RT-qPCR results showed that urinary level of miR-3613-3p was significantly lower in IgAN than that in MN, MCD and healthy controls (0.47, 0.44 and 0.24 folds, respectively, all P < 0.01 by Mann-Whitney U test); urinary level of miR-4668-5p was also significantly lower in IgAN than that in healthy controls (0.49 fold, P < 0.01). Significant correlations were found between urinary levels of miR-3613-3p with 24-hour urinary protein excretion (Spearman r = 0.50, P = 0.034), eGFR (estimated glomerular filtration rate) (r = - 0.48, P = 0.043) and Lee's grades (r = 0.57, P = 0.014). Similarly, miR-4668-5p was significantly correlated with eGFR (r = - 0.50, P = 0.034) and Lee's grades (r = 0.57, P = 0.013). For segmental glomerulosclerosis according to Oxford classification, patients scored as S0 had significantly lower levels of urinary miR-3613-3p and miR-4668-5p than those scored as S1 (0.41 and 0.43 folds, respectively, all P < 0.05). Conclusions. The expression profile of miRNAs was significantly altered in urinary sediments from patients with IgAN. Urinary expression of miR-3613-3p was down-regulated in patients with IgAN. Moreover, urinary levels of both miR-3613-3p and miR-4668-5p were correlated with disease severity. Further studies are needed to explore the roles of miR-3613-3p and miR-4668-5p in the pathogenesis and progression of IgA nephropathy.

Abstract
BACKGROUND MicroRNA 146a (miR-146a) is a 19 to 23 nucleotide long, small non-coding RNA with gene regulatory functions that has influence on the pathogenesis of many diseases. A single nucleotide polymorphism (rs2910164 C>G) in pre-miR-146a is correlated with the expression of miR-146a. The aim of this study was to perform an association analysis of rs2910164 with IgA nephropathy in adult patients from a Chinese Han population. METHODS A total of 145 patients with renal biopsy-proved IgA nephropathy (IgAN) and 179 healthy controls were recruited to the current study. rs2910164 was genotyped by the polymerase chain reaction (PCR) and high-resolution melting methods (HRM). Clinical characteristics and pathology grading of patients with IgAN were recorded at the time of kidney biopsy. RESULT There were significant differences among the population of patients grouped by different age of onset in a co-dominant model (CG vs. CC vs. GG) (p = 0.033) and a recessive model (CG+CC vs. GG) (p = 0.001). However, no significant difference was observed in the distribution of genotypes between cases and controls (p = 0.144). There was also no significant difference between rs2910164 and patient quantitative traits (all p > 0.003) or different pathology grading (Lee's grading system and tubular atrophy/interstitial fibrosis in the Oxford classification) (all p > 0.05). CONCLUSIONS There was no association of rs2910164 with susceptibility to IgAN in adults from a Chinese Han population. However, rs2910164 was correlated with the age of onset of IgAN in adult patients.

Abstract
IgA nephropathy is the most common primary glomerulonephritis and presents with gross hematuria and upper respiratory infection, with slow progression to end-stage renal disease in up to 50% of affected patients. Kidney biopsies are the gold standard method of diagnosis and frequently are not performed as the majority of individuals are asymptomatic. Thus, there is a need to discover and validate prognostic and predictive biomarkers that can be noninvasively obtained and are specific to this disease. Here we discuss the current state of research in this area and examine validated and clinically promising biofluid and tissue biomarkers of IgA nephropathy.

Abstract
BACKGROUND Micro-RNAs (miRNAs) play important roles in the regulation of immune response and inflammation. The purpose of this study was to investigate the association between three single nucleotide polymorphisms (SNPs) (mir-146a rs2910164, let-7a-2 rs1143770, miR-196a2 rs11614913) and susceptibility to and severity of childhood immunoglobulin A (IgA) nephropathy (IgAN). METHODS We genotyped three miRNA SNPs in two independent Han Chinese populations composed of 158 patients and 265 controls (discovery set), and 246 patients and 446 controls (validation set), respectively. RESULTS We found that rs2910164 was significantly associated with IgAN in the discovery but not the validation set. Combined analysis revealed that rs2910164 CC and CG genotypes were associated with increased risk of IgAN compared with the GG genotype [adjusted odds ratios (OR) = 1.684, 95 % confidence interval (CI)1.190-2.384, P = 0.003; adjusted OR = 1.472, 95 % CI 1.079-2.007, P = 0.015, respectively). We also found that the frequency of the rs2910164 CC genotype was significantly higher in patients with Haas grade III-V than in those with Haas grade I-II for all study populations (P < 0.05). The expression of miR-146a in normal renal tissues with CC genotype was lower than in those with a G allele (P = 0.038). CONCLUSIONS These results indicated that rs2910164 may affect the susceptibility and severity of pediatric IgAN. Further studies are needed to validate these findings.

Abstract
OBJECTIVES Our aim in this study was to identify and examine the differential expression of microRNAs in patients with systemic lupus erythematosus (SLE). METHODS We employed high-quality, high-throughput Solexa sequencing to clone and identify microRNAs in SLE patients and a control group. RESULTS From the sequencing data, we identified numerous microRNAs displaying significantly different levels of expression in patients with SLE and in healthy controls. The 212 and 199 microRNAs were upregulated and downregulated, respectively. Only 61 novel microRNAs exhibited significantly different levels of expression in the two groups. The target genes of the novel microRNAs identified in the SLE group were found to have cell metabolism functions. We also analyzed the chromosomal locations of the microRNAs with high level of expression between the two groups. A profile comparison revealed that the majority of transcripts were expressed at a similar level. The functional classes of the most abundant microRNAs were equally represented on each chromosome. CONCLUSION We identified novel and known microRNAs significantly enhancing our understanding of the microRNA expression profiles of SLE patients. These data also provide insight into the function of microRNAs in SLE and provide new strategies for future therapies.

Abstract
IgA nephropathy is globally the most common primary glomerulonephritis, but the pathogenesis of this condition is still only partially understood. MicroRNAs (miRNAs) are short, noncoding RNA molecules that regulate gene expression. Genome-wide analysis of renal miRNA expression has identified a number of novel miRNAs related to immunological and pathological changes. Specifically, overexpression of miR-148b might explain the aberrant glycosylation of IgA1, which has a central pathogenetic role in the early phase of IgA nephropathy. By contrast, miR-29c is an antifibrotic miRNA that is probably important in the late stages of disease progression. In addition, urinary levels of several miRNAs are significantly changed in patients with IgA nephropathy compared with healthy individuals; some alterations seem to be disease-specific, whereas others are apparently damage-related. As miRNAs in urinary sediment are relatively stable and easily quantified, they have the potential to be used as biomarkers for the diagnosis and monitoring of disease. However, to date, limited data are available on the role of miRNAs in the pathogenesis of IgA nephropathy and their potential application as biomarkers. Consequently, further studies are urgently needed to address this shortfall. Here, we review the available literature on miRNAs in relation to IgA nephropathy.

The last decade has seen major progress in understanding the pathogenesis as well as the prognosis and treatment of patients with IgA nephropathy (IgAN). Although the diagnostic criterion of a kidney biopsy demonstrating dominant or codominant IgA deposition remains unchanged, much more is known about the genetic and environmental factors predisposing to disease development and progression. These advances have led to the identification of novel diagnostic and prognostic markers. Among the most promising clinically are genetic profiling, quantification of galactose-deficient IgA1 levels, and measurement of anti-IgA1 immunoglobulins. While targeted treatment for IgAN remains elusive, there is mounting evidence for therapeutic interventions that alter the disease course. The appropriate validation and integration of these discoveries into clinical care represent a major challenge, but one that holds tremendous promise for refining prognostication, guiding therapy, and improving the lives of patients with IgAN.
