ABSTRACT: Quantitative TMT experiment on UPJO urine. Contains controls and patients with UPJO. "A", "B", "C", and "D" each correspond to two triplet sets of samples: 1 UPJO kidney urine, 1 UPJO bladder urine, and 1 healthy control.
Project description:Background: Bladder-sparing trimodality therapy (TMT) is an alternative to radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC), and biomarkers to inform therapy selection are needed. Objective: To evaluate immune and stromal signatures in MIBC treated with TMT.
Project description:Objective was to identify urine cell-free microRNAs enabling early non-invasive detection of bladder cancer. Total RNA enriched for fraction of short RNAs was isolated using Urine microRNA purification kit (Norgen corp.). miRNA profiles were determined using the Affymetrix GeneChip miRNA 3.0 array and analyzed to identify differentially deregulated miRNA in bladder cancer patients compared with helathy controls.
Project description:Mid-stream urine was collected from bladder cancer patients prior to surgery. Both tumor tissue and normal bladder mucosa that are located at >3cm away from the tumor edge were obtained by cystoscopy. For the normal controls with haematuria, urine samples were collected from patients who had normal cystoscopic finding and absence of malignancy with >6 months follow-up. All urine samples were centrifuged at 2500 r.c.f. for 20 minutes and the urine supernatant was collected. Total RNA of urine supernatant and frozen tissue was extracted using MirVanaTM PARISTM Kit (Ambion) in accordance with the manufacturerâs recommended protocols. AgilentTM Human miRNA Microarray Chip (Release 13.0, Agilent Technologies, Santa Clara, CA, USA) was used to determine the microRNA expression profiles of the samples.
Project description:We aimed to identify urinary exosomal ncRNAs as novel biomarkers for diagnosis of Chronic Kidney Disease (CKD) for this, we examined 15 exosomal ncRNA profiles in urine samples from CKD patients from four different stages (I, II, III and IV) and compared them to 10 healthy controls. We identified a significant number of novel, differentially expressed ncRNAs in CKD patients compared to healthy, which might be employed as early diagnostic markers in CKD in the future.
Project description:Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic and debilitating pain disorder of the bladder and urinary tract with poorly understood etiology. A definitive diagnosis of IC/BPS can be challenging because many symptoms of IC/BPS are shared with other urological disorders. An analysis of urine presents an attractive and non-invasive resource for monitoring and diagnosing IC/BPS. Here, a non-targeted LC-MS and LC-MS/MS-based peptidomics analysis of urine samples collected from IC/BPS patients were compared to urine samples from asymptomatic controls.
Project description:The mammalian ureter is a tube connecting the kidney with the urinary bladder. The differentiated urothelial tube is surrounded by smooth muscle cells (SMCs). In mice embryos by E15, the first SM cells have formed and, over the next few prenatal days, the ureter becomes a functional unit, transmitting urine generated by the metanephros. Molecules in the transforming growth factor-beta (TGFB) axis have been reported to be upregulated in both kidney and ureter malformations. This study reports the effects of TGFB1 treatment on E15 mouse ureters in vitro.
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.

Project description:High Resolution Isoelectric Focusing (HiRIEF) LC-MS was used to analyze samples from the human A431 cell line and also samples of histologically normal tissues. The high analytical depth afforded by HiRIEF permitted proteogenomics on these two sample sets (A431 cells and normal tissues). The A431 data was obtained from a time course experiment upon Gefitinib treatment (EGFR inhibition) of A431 cells with harvests at 2h, 6h and 24h after treatment as well of untreated cells. Isobaric tag labelling of peptide samples with TMT10plex was used. Biological triplicate controls (TMT channels 126, 127N, 127C), duplicate 2h (128N, 128C), duplicate 6h (129N, 129C) and triplicate 24h (130N, 130C, 131) samples were employed. The normal tissues data was obtained from two separate TMT10plex sets. TMT set1 was composed of 9 samples, all from different individuals, including three placenta samples (126, 127N, 127C) two liver samples (128N, 128C), two kidney samples (129N, 129C), two tonsil samples (130N, 130C), plus an internal pooled standard (131). TMT set2 was composed of 8 samples, all from different individuals, including one tonsil sample (126), two liver samples (127C, 128N), two kidney samples (128C, 129N), three testis samples (129C, 130N, 130C), plus an internal pooled standard (131). The internal pooled standard was made by combining equal aliquots of the tryptic peptide mixtures from each of the 17 tissue samples.
