Project description:Extracellular Small RNA Profiles in Plasma, Urine and Saliva from College Athletes
| PRJNA357870 | ENA
Project description:<p>There are currently few datasets describing baseline expression levels for total cell-free circulating RNA from healthy control subjects. Total extracellular RNA was isolated from plasma, urine, and saliva samples from healthy controls. We sequenced small RNAs from 183 plasma samples, 204 urine samples and 46 saliva samples from 55 college athletes ages 18-25 years. Many of the participants provided more than one sample, weeks or months apart, allowing us to assess variability in an individual's exRNA expression levels over time. Several individuals provided all three biofluid types at one time, producing data on individual expression levels across several biofluid types. Here we provide a systematic analysis of small exRNAs present in each biofluid, as well as an analysis of exogenous RNAs. We find that a large number of RNA fragments in plasma (63%) and urine (54%) have sequences that are assigned to YRNA and tRNA fragments respectively. Surprisingly, while many miRNAs can be detected, there are few miRNAs that are consistently detected in all samples from a single biofluid.</p>

Project description:Small extracellular vesicles (sEV) are nano-sized (40-150 nm), membrane-encapsulated vesicles that are released by malignant or pathologic and non-pathologic cells into the extracellular space and function as intercellular signaling vectors through the horizontal transfer of biologic molecules, including microRNA (miRNA) and other small non-coding RNA (ncRNA), that can alter the phenotype of recipient cells. sEV are present in essentially all extracellular biofluids, including serum, urine and saliva, and offer a new avenue for discovery and development of novel biomarkers of various disease states and exposures. The objective of this study was to determine the similarities and differences between sEV ncRNA derived from saliva, serum and urine, as well as cell-free ncRNA from serum. Saliva, urine and serum were concomitantly collected from 4 healthy donors, and sEV were isolated from each respective biofluid, along with cfRNA from serum. sEVs were isolated from the respective biofluids via differential ultracentrifugation. Small RNA-sequencing was performed on each sample, and cluster analysis was performed based on ncRNA profiles. While some similarities existed in terms of sEV ncRNA cargo across biofluids, there are also notable differences in ncRNA class and ncRNA secretion, with each sEVs in each biofluid bearing a unique ncRNA profile. We conclude that sEV ncRNA cargo varies according to biofluid, so thus should be carefully selected and interpreted when designing translational or epidemiological studies.

Project description:Exsome microRNA stably present in various body fluids (such as amniotic fluid, breast milk, blood, bronchial lavage, malignant ascites fluid, tears, saliva, and urine) shown to be associated with various pathological conditions. We report the microRNA expression profiles in porcine serum, plasma, semen, urine and bile exsome at postnatal 180-days-old by a deep sequencing technology.

Project description:Endogenous and exogenous extracellular RNAs will be characterized in four body fluids (plasma, serum, CSF and saliva) collected at the same time from 134 healthy subjects ranging in age from 31 to 101 years old. Small RNAs contained in these samples will be profiled by small RNA-seq using unfractionated biofluids and purified extracellular vesicles.

Project description:Saliva is a convenient non-invasive source of liquid biopsy to monitor human health and diagnose diseases. In particular, extracellular vesicles (EVs) in saliva can potentially reveal clinically relevant information for systemic health. Recent studies have shown that RNA in saliva EVs could be exploited as biomarkers for disease diagnosis. However, there is no standardized protocol for profiling RNA in saliva EV nor clear guideline on selecting saliva fractions for biomarker analysis. To address these issues, we established a robust protocol for small RNA profiling from fractionated saliva. With this method, we performed comprehensive small RNA sequencing of four saliva fractions, including cell-free saliva (CFS), EV-depleted saliva (EV-D), exosome (EXO), and microvesicle (MV) from ten healthy volunteers.

Project description:In this study, small RNAs were isolated from individual donations of eight forensically relevant biological fluids (blood, semen, vaginal fluid, menstrual blood, saliva, urine, feces, and perspiration) and subjected to next generation sequencing using the Illumina® Hi-Seq platform. Sequencing reads were aligned and annotated against miRbase release 21, resulting in a list of miRNAs and their relative expression levels for each sample analyzed. Body fluids with high bacterial loads (vaginal fluid, saliva, and feces) yielded relatively low annotated miRNA counts, likely due to oversaturation of small RNAs from the endogenous bacteria. Both body-fluid specific and potential normalization miRNAs were identified for further analysis as potential body fluid identification tools for each body fluid. 32 samples - 3-5 replicates of each human biological fluid: venous blood, urine, semen (normal and vasectomized), vaginal secretions, menstrual secretions, perspiration, feces, saliva
