An Innovative Method for Exosome Quantification and Size Measurement
Although the biological importance of exosomes has recently gained an increasing amount of scientific and clinical attention, much is still unknown about their complex pathways, their bioavailability and their diverse functions in health and disease. Current work focuses on the presence and the behavior of exosomes (in vitro as well as in vivo) in the context of different human disorders, espec...
متن کاملDifferential protein profiling of renal cell carcinoma urinary exosomes.
Renal cell carcinoma (RCC) accounts for about 3% of all human malignancies and its incidence is increasing. There are no standard biomarkers currently used in the clinical management of patients with renal cell carcinoma. A promising strategy for new biomarker detection is comparative proteomics of urinary exosomes (UE), nanovesicles released by every epithelial cell facing the urinary space, e...
متن کاملWilm's Tumor-1 Protein Levels in Urinary Exosomes from Diabetic Patients with or without Proteinuria
BACKGROUND Podocyte injury is an early feature of diabetic nephropathy (DN). Recently, urinary exosomal Wilm's tumor-1 protein (WT1), shed by renal epithelial cells, has been proposed as a novel biomarker for podocyte injury. However, its usefulness as biomarker for early diabetic nephropathy has not been verified yet. We investigated urinary exosomal WT1 in type-1 diabetic patients to confirm ...
متن کاملUrinary exosomes: is there a future?
Tiny vesicles called ‘exosomes’, recently discovered in normal urine [1], provide a non-invasive means of acquiring unique information about the physiological or pathophysiological state of their renal cells of origin. Exosomes are delivered to the urine from all renal epithelial cell types. Consequently, analysis of urinary exosomes may provide a source of protein biomarkers for diseases invol...
متن کاملDevelopment of Glomerulus-, Tubule-, and Collecting Duct-Specific mRNA Assay in Human Urinary Exosomes and Microvesicles
Urinary exosomes and microvesicles (EMV) are promising biomarkers for renal diseases. Although the density of EMV is very low in urine, large quantity of urine can be easily obtained. In order to analyze urinary EMV mRNA, a unique filter device to adsorb urinary EMV from 10 mL urine was developed, which is far more convenient than the standard ultracentrifugation protocol. The filter part of th...
