Treatment effectiveness for kidney disease is limited by lack of accuracy, sensitivity, specificity of diagnostic, prognostic, and therapeutic biomarkers. The gold standard test renal biopsy along with serum creatinine and proteinuria is often necessary to establish a diagnosis, particularly in glomerular disease. Proteomics has become a powerful tool for novel biomarker discovery in kidney disease. Novel proteomics offer earlier and more accurate diagnosis of renal pathology than possible with traditional biomarkers such as serum creatinine and urine protein...

BACKGROUND: The urinary proteomic classifier CKD273 has shown promise for prediction of progressive diabetic nephropathy (DN). Whether it is also a determinant of mortality and cardiovascular disease in patients with microalbuminuria (MA) is unknown. METHODS: Urine samples were obtained from 155 patients with type 2 diabetes and confirmed microalbuminuria. Proteomic analysis was undertaken using capillary electrophoresis coupled to mass spectrometry to determine the CKD273 classifier score...

PURPOSE: Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a life-long disease in which the genes responsible are known, but the pathogenesis of cyst formation and cyst growth are not understood. Cyst growth ultimately leads to end stage renal failure in most patients. Analysis of the urinary proteome offers the potential to identify proteins that indicate the presence of cysts (and thus provides diagnosis) as well as the rates of cyst growth (providing prognostic information). EXPERIMENTAL DESIGN: We performed scheduled Parallel Reaction Monitoring (sPRM) assay on urine samples from 14 patients and 18 normal controls...

Based on density differences of different subpopulations of exosomes, two kinds of micro-vesicles with different densities were captured from urine by a modified sucrose density gradient ultracentrifuge separation method. Verified by transmission electron microscope (TEM) and western blot, the results showed these two kinds of micro-vesicles were all exosomes. And these two kinds of exosomes were analyzed by TEM, two dimensional electrophoresis (2DE) and capillary zone electrophoresis (CZE), respectively. The results of TEM showed these two exosomes with different densities have different morphological characteristics, and some tiny proteomic differences were shown in the results of 2DE of these two exosomes...

Proteomic analysis of extracellular vesicles (EV) from biological fluid is a powerful approach to discovery of potential biomarkers for human diseases including cancers, as EV secreted to biological fluids are originated from the affected tissue. In order to investigate significant molecules related to the pathogenesis of bladder cancer, EVs were isolated from patient urine which was analyzed by mass spectrometry based proteomics. Comparison of the EV proteome to the whole urine proteome demonstrated an increased number of protein identification in EV...

BACKGROUND: /Aims: Renal disease is a common cause of morbidity in patients with Bardet-Biedl syndrome (BBS), however the severity of kidney dysfunction is highly variable. To date, there is little information on the pathogenesis, the risk and predictor factors for poor renal outcome in this setting. The present study aims to analyze the spectrum of urinary proteins in BBS patients, in order to potentially identify 1) disease-specific proteomic profiles that may differentiate the patients from normal subjects; 2) urinary markers of renal dysfunction...

Urine is a better source than plasma for biomarker studies, as it can accumulate all changes in the body. Various candidate urinary biomarkers of physiological condition, kidney disease and even brain dysfunction, have been detected in urine; however, urine has rarely been used to reflect cardiac diseases. In this study, urine at day 0, 14, 21 and 28 were collected from the myosin-induced autoimmune myocarditis rat models. The candidate urinary biomarkers were then characterized using the isobaric tandem mass tag labeling approach coupled with offline two-dimensional reverse-phase liquid chromatography and high-resolution mass spectrometry...

Background: IgA nephropathy (IgAN) is the most common primary glomerulonephritis diagnosed based on renal biopsy. Mesangial IgA deposits along with the proliferation of mesangial cells are the histologic hallmark of IgAN. Non-invasive diagnostic tools may help to prompt diagnosis and therapy. The discovery of potential and reliable urinary biomarkers for diagnosis of IgAN depends on applying robust and suitable models. Applying two multivariate modeling methods on a urine proteomic dataset obtained from IgAN patients, and comparison of the results of these methods were the purpose of this study...

AIMS: In this study, we applied quantitative proteomic analysis to identify urinary proteins associated with diabetic nephropathy (DN). METHODS: Two-dimensional image-converted analysis of liquid chromatography and mass spectrometry detected the proteins differentially excreted between normoalbuminuric and macroalbuminuric patients with type 2 diabetes mellitus (T2DM) (n = 6 each). Urinary levels of excreted proteins were measured by multiple reaction monitoring (MRM) analysis using an independent sample set (n = 77)...

Chronic kidney disease (CKD) is a progressive condition characterized by a permanent and irreversible loss of renal function. In accordance to international guidelines, CKD clinical diagnosis methods are based on creatinine and albumin levels and glomerular filtration rate. Unfortunately, these parameters are scarcely affected in early stages, and its inherent intrinsic variability only allows for the identification of intermediate and advanced stages, when life expectancy has become shorter and treatment poses a significant financial investment...

Advances in technology and computing now permit the high-throughput analysis of multiple domains of biological information, including the genome, transcriptome, proteome, and metabolome. These omics approaches, particularly comprehensive analysis of the genome, have catalyzed major discoveries in science and medicine, including in nephrology. However, they also generate large complex data sets that can be difficult to synthesize from a clinical perspective. This article seeks to provide an overview that makes omics technologies relevant to the practicing nephrologist, framing these tools as an extension of how we approach patient care in the clinic...

BACKGROUND: Acute kidney injury (AKI) diagnosis is based on a rise in serum creatinine and/or fall in urine output. It has been shown that there are patients that fulfill AKI definition but do not have AKI, and there are also patients with evidence of renal injury who do not meet any criteria for AKI. Recently the innovative and emerging proteomic technology has enabled the identification of novel biomarkers that allow improved risk stratification. METHODS: Tissue inhibitor of metalloproteinases-2 (TIMP-2), insulin-like growth factor-binding protein 7 (IGFBP7) were measured to a cohort of 719 consecutive patients admitted to Intensive Care Unit (ICU)...

Advanced glycation end products (AGEs) are stable posttranslational modifications of proteins formed by the spontaneous reaction with glucose and related metabolites. Important AGEs quantitatively are methylglyoxal (MG)-derived hydroimidazolone MG-H1, Nε -carboxymethyl-lysine (CML), and glucosepane. They contribute to the development of chronic kidney disease (CKD). Cellular proteolysis of AGE-modified proteins forms AGE free adducts, glycated amino acids, which are cleared by the kidneys and excreted in urine...

AIMS: Historically, urine has been viewed primarily as a waste product with little biological role in the overall health of an individual. Increasingly, data suggest that urine plays a role in human health beyond waste excretion. For example, urine might act as an irritant and contribute to symptoms through interaction with-and potential compromise of-the urothelium. METHODS: To explore the concept that urine may be a vehicle for agents with potential or occult bioactivity and to discuss existing evidence and novel research questions that may yield insight into such a role, the National Institute of Diabetes and Digestive and Kidney Disease invited experts in the fields of comparative evolutionary physiology, basic science, nephrology, urology, pediatrics, metabolomics, and proteomics (among others) to a Urinology Think Tank meeting on February 9, 2015...

Mammalian olfaction depends on chemosensory neurons of the main olfactory epithelia (MOE), and/or of the accessory olfactory epithelia in the vomeronasal organ (VNO). Thus, we have generated the VNO and MOE transcriptomes and the nasal cavity proteome of the house mouse, Mus musculus musculus . Both transcriptomes had low levels of sexual dimorphisms, while the soluble proteome of the nasal cavity revealed high levels of sexual dimorphism similar to that previously reported in tears and saliva. Due to low levels of sexual dimorphism in the olfactory receptors in MOE and VNO, the sex-specific sensing seems less likely to be dependent on receptor repertoires...

Amyloidosis is a heterogeneous group of diseases characterised by extracellular accumulation of amyloid in various tissues and organs of the body, leading to alteration and destruction of tissues. Heart involvement is the most important prognostic factor in patients with systemic amyloidosis and the diagnosis and typing of amyloid must be made properly. The clinical picture shows congestive heart failure with predominant right-sided heart failure symptoms in fully developed disease, various types of arrhythmias and characteristic electrocardiography and echocardiography findings...

Background: Primary membranous nephropathy (PMN) is an important cause of nephrotic syndrome in adults. Urine proteome may provide important clues of pathophysiological mechanisms in PMN. In the current study, we analyzed and compared the proteome of urine from patients with PMN and normal controls. Methods: We performed two technical replicates (TMT1 and TMT2) to analyze and compare the urine proteome from patients with PMN and normal controls by tandem mass tag (TMT) technology coupled with nanoscale liquid chromatography tandem mass spectrometry analysis (LC-MS/MS)...

Autosomal dominant tubulointerstitial kidney disease associated to the MUC1 gene (ADTKD-MUC1; formerly MCKD1) belongs to a heterogenous group of rare hereditary kidney diseases that is prototypically caused by frameshift mutations in the MUC1 repeat domain. The mutant MUC1(insC) lacks the transmembrane domaine, exhibits aberant cellular topology and hence might gain a function during the pathological process. To get insight into potential pathomechanisms we performed differential proteomics of extracellular vesicles shed by renal epithelia into the urine of patients...

Diabetic mellitus (DM) is a disease that affects glucose homeostasis and causes complications, such as diabetic nephropathy (DN). For early diagnosis of DN, microalbuminuria is currently one of the most frequently used biomarkers. However, more early diagnostic biomarkers are desired in addition to microalbuminuria. In this study, we performed comprehensive proteomics analysis of urine proteomes of diabetic mellitus patients without microalbuminuria and healthy volunteers to compare the protein profiles by mass spectrometry...
