Urinary proteome of a healthy human cohort aged 70 to 82

ABSTRACT: 12 urine samples from 6 individuals (2 time points each) enrolled in a study on healthy aging were collected. Samples were frozen at -80⁰C prior to analysis. Samples were thawed, pH neutralized, separated into soluble urine (SU) and urinary pellet (UP) fractions, and subjected to filter aided sample preparation (FASP). FASP-processed samples were subjected to LC-MS/MS analysis on a Q Exactive mass spec.

Inflammation in the urinary tract results in a urinary proteome characterized by a high dynamic range of protein concentrations and high variability in protein content. This proteome encompasses plasma proteins not resorbed by renal tubular uptake, renal secretion products, proteins of immune cells and erythrocytes derived from trans-urothelial migration and vascular leakage, respectively, and exfoliating urothelial and squamous epithelial cells. We examined how such proteins partition into solu ...[more]

Urine-HILIC – An automated sample preparation for bottom-up urinary proteome profiling in clinical proteomics

Project description:Urine provides a diverse source of information related to health status and is ideal for clinical proteomics because of its ease of collection. To date, there is no standard operating procedure for reproducible and robust urine sample processing for mass spectrometry-based clinical proteomics. To address this need, a novel workflow was developed based on an on-bead protein capture, clean up, and digestion without the requirement from pre-processing steps such as precipitation. The workflow was applied to an acute kidney injury (AKI) pilot study. Urine from clinical samples and a pooled sample were subjected to automated sample preparation in a KingFisher™ Flex magnetic handling station using a novel urine-HILIC (uHLC) approach based on MagReSyn® HILIC microspheres. For benchmarking, the pooled sample was also prepared using a published protocol based on an on-membrane (OM) protein capture and digestion workflow. Peptides were analysed by LCMS in DIA mode using a Dionex Ultimate 3000 UPLC coupled to a Sciex 5600 mass spectrometer. Data was searched in Spectronaut™ 17. Following statistical analysis, candidate protein markers were filtered at ≥ 2-fold change in abundance, ≥ 2 uniques peptides and ≤ 1% false discovery rate. Both workflows showed similar peptide and protein identifications in the pooled sample. The uHLC workflow was easier to set up and complete, having less hands-on time than the OM method. With fewer manuel processiing steps, a lower peptide and protein CV was observed in the uHLC technical replicates. Analysis of clinical samples revealed many significant, differentially abundant kidney injury-associated urinary proteins. The pilot data derived using this novel workflow provides information on the urinary proteome of patients with AKI. Further exploration in a larger cohort using this novel high-throughput method is warranted.

A urine storage protocol that is feasible with at home self-sampling for extracellular vesicle proteomics

Project description:Urine is a non-invasive biofluid for the identification of biomarkers to detect disease. In particular extracellular vesicles (EVs) have gained increased interest as a biomarker source, because the molecular content is protected against degradation. Clinical implementation on a daily basis requires protocols that inevitably includes short-term storage of the clinical samples, especially when samples are collected at home. However, little is known about the effect of delayed processing on the urinary EVs and their proteome. In the current study, we evaluated two different storage protocols. First, urine stored at 4˚C without any preservative, and second, a protocol compatible with at-home collection, urine with 40 mM EDTA stored at room temperature. For both conditions it was determined whether storage for 0, 2, 4 and 8 days leads to a change in the global urinary EV proteome profile using proteomics based on data-independent acquisition mass spectrometry. We show that EDTA does not affect the global proteome. Remarkably, the EV proteome was stable in both urine stored up to a week at room temperature with EDTA and in urine stored at 4˚C. These findings open up biomarker studies in urine collected via self-sampling.

Human Urinary Proteome in Vesicoureteral Reflux

Project description:Vesicoureteral reflux (VUR) is a common pediatric condition that predisposes children to renal damage after urinary tract infection (UTI). We profiled the urinary proteome of VUR patients with recurrent UTI and renal scarring to identify potential biomarkers characterizing this condition. Urine was obtained from 22 age-matched controls and 22 patients with low grade VUR (1-3 out of 5), renal scarring, and history of recurrent UTI. Proteins extracted from these samples were analyzed by mass spectrometry for protein identification and quantitation for comparison.

Single-Cell RNA-Seq Analysis of cells from human urine

Project description:Urine passes through the entire kidney and urinary tract system starting from the glomerulus and ending to the urethra. Cells in the kidney and urinary tract could be exfoliated from the epithelium into the urine, while leukocyte could infiltrate from the local tissue into the urine, which makes the urine a useful subject for clinical evaluation of relevant diseases. We performed scRNA-seq on voided urine samples. 50–100 mL middle stream urine samples were collected from 12 Chinese healthy adults and combined for droplet-based single-cell RNA sequencing after flow cytometric sorting of live cells. We presented the first single-cell atlas of adult human urine and identified multiple previously unrecognized cell types. Based on our scRNA-seq analysis data, a SOX9+ cell population was identified in adult human urine which we speculated to have progenitor potential.

Urinary single cell profiling captures cellular diversity of the kidney

Project description:We performed single cell transcriptomic analysis on 17 urine samples obtained from five subjects at two different occasions using both spot and 24-hour urine collection. In addition, we used a combined spot urine samples of five healthy individuals as a control sample. We sequenced a total of 71,667 cells. After quality control and downstream analysis, we found that epithelial cells were the most common cell types in the urine. We were also able to identify most kidney cell types in the urine, such as podocyte, proximal, and collecting duct (CD), in addition to macrophages, monocytes and lymphocytes.

Multiomics Analyses of Vesicular Transport Pathway-Specific Transcripts and Proteins in Ovine Amnion: Responses to Altered Intramembranous Transport

Project description:Amniotic fluid (AF) volume (AFV) is determined primarily by the rate of intramembranous (IM) transport of AF across the amnion. Intramembranous transport is characterized as vesicular endocytotic and transcytotic processes regulated by fetal urine-derived stimulators and AF inhibitors. Our objectives were to utilize a large-scale multiomics approach to decipher the vesicular transport pathways in the amnion and to identify potential transport regulators in AF and fetal urine. We utilized fetal sheep to experimentally induce alterations in IM transport rate and analyze the expression profiles of transcripts and proteins in amnion, AF and fetal urine. Four experimental groups were studied: control (C), urine drainage with reduced IM transport rate and AFV (UD), urine drainage and fluid replacement with decreased IM transport rate but increased AFV (UDR), and intra-amniotic fluid infusion with augmented IM transport rate and AFV (IA). Amnion and fluid samples were subjected to transcriptomics (RNA-Seq) and proteomics studies followed by bioinformatics analyses using Ingenuity Pathway Analysis software. The analyses revealed 9 functional transport pathways and a panel of differentially expressed transcripts and proteins that are known mediators of vesicular transport and energy metabolism. During UD, expressions of endocytosis and trafficking mediators were reduced as compared to controls. Under UDR, expressions of energy metabolism activators increased while trafficking mediators decreased. During IA, expressions of vesicular uptake and transcellular trafficking regulators were enhanced. Co-expression of the motor protein, cytoplasmic dynein light chain-1, in both AF and fetal urine suggest that this molecule may function as a urine-derived stimulator of IM transport.
