The miRNAs in plasma exosomes may serve as markers for segmental vitiligo

ABSTRACT: More and more studies have showed that plasma exosomal miRNAs are biomarkers for disease. The aim of the study were to investigate the miRNA profiling in plasma exosomes of patients with segmental vitiligo (SV) and to find biomarkers in plasma exosomes for patients with SV. Plasma exosomes and exosomal RNA of 7 SV patients and 8 health persons were purified by exoRNeasy Serum/Plasma Maxi Kit. The miRNA profiles of the 15 samples were sequenced using HiSeq 2500 (Illumina) and analyzed by Reads Per Million (RPM) values and edgeR algorithm. Some differently expressed miRNAs in plasma exosomes and skin tissues of the two sets were validated by qRT–PCR.A total of 85 miRNAs in plasma exosomes showed differential expression between SV patients and health persons, with a |log2（Fold Change）|≥1 and P-value < 0.05. Several miRNAs were confirmed by qRT–PCR and showed similar expression patterns between plasma exosomes and skin tissues. Our study depict the miRNAs expression profiles in plasma exosomes of SV patients and suggest that several miRNAs in plasma exosomes may serve as biomarkers for SV.

The miRNAs in plasma exosomes may serve as markers for non-segmental vitiligo

Project description:More and more studies have showed that plasma exosomal miRNAs are biomarkers for disease. The aim of the study were to investigate the miRNA profiling in plasma exosomes of patients with non-segmental vitiligo (NSV) and to find biomarkers in plasma exosomes for patients with NSV. Plasma exosomes and exosomal RNA of 10 NSV patients and 10 health persons were purified by exoRNeasy Serum/Plasma Maxi Kit. The miRNA profiles of the 20 samples were sequenced using HiSeq 2500 (Illumina) and analyzed by Reads Per Million (RPM) values and edgeR algorithm. Some differently expressed miRNAs in plasma exosomes and skin tissues of the two sets were validated by qRT–PCR.Several miRNAs were confirmed by qRT–PCR and showed similar expression patterns between plasma exosomes and skin tissues.

Small RNA-Seq of plasma-derived exosomes from Acute Respiratory Distress Syndrome patients and healthy subjects

Project description:Despite a significant progress in the treatment of Acute Respiratory Distress Syndrome (ARDS), our ability to identify early patients and predict outcome remains limited. In this study, we aimed to characterize small RNA content of plasma exosomes from ARDS patients in order to identify potential diagnostic biomarkers of the disease. For the first time, we profiled miRNA expression levels in plasma-derived exosomes from ARDS patients (n=8) compared to healthy subjects (n=10) by small RNA-seq. It allowed us to identify 12 exosomal miRNAs differentially expressed in ARDS context (padj<0.05).

Expression data of exosomal miRNAs extracted from plasma [Affymetrix miRNA 4.0]

Project description:Tuberculosis (TB) is difficult to diagnose under complex clinical conditions. Exosomal miRNAs have emerged as promising disease biomarkers. We aim to investigate the potential of exosomal miRNAs to assist with TB clinical diagnosis. In the present research, we used the Affymetrix Genechip miRNA 4.0 Array to investgate the profiles of differentially expressed miRNAs (DEMs) in the exosomes of peripheral blood plasma. As a result, exosomal miRNA profiling yielded a total of 102 DEMs (98 with up-expression and 4 with down-expression) between the TB (pulmonary tuberculosis and tuberculosis meningitis) patients and controls.

RNA-seq reveals abundant circRNA, lncRNA and mRNA in blood exosomes of normal persons

Project description:Exosomes are small membrane vesicles of endocytic origin secreted by most cells, and contain a wealthy cargo of protein and RNA species that can modulate recipient cells’ behaviors and may be used as biomarkers for diagnosis of human diseases. They have been found in blood and are valuable sources for biomarkers due to selective cargo loading and resemblance to their parental cells. The goal of this study is to identify circRNA, lncRNA and mRNA profiles in human blood by high-throughput RNA sequencing (RNA-seq). 1-4 ml plasma or serum were used to extract exosomal RNAs by exoRNeasy Serum/Plasma Maxi kit (Qiagen). The exosomal RNAs were further treated with DNAse I and subjected to ribosome minus low-input RNAseq library preparation. The libraries were sequenced by Illumina Hiseq platform.

Exosomal miR-1290 and miR-375 as prognostic markers in castrate resistant prostate cancer

Project description:Extracellular microRNAs (miRNAs) embedded in circulating exosomes may serves as prognostic biomarkers in cancer. This study was performed to identify and evaluate plasma exosomal miRNAs for prognostication in castration resistant prostate cancer (CRPC). RNA sequencing was performed to identify candidate exosomal miRNAs associated with overall survival in a screening cohort of 23 CRPC patients. Candidate miRNAs were further evaluated for prognosis using qRT-PCR in a follow-up cohort of 100 patients. Cox regression and Kaplan–Meier survival curve analysis were used to evaluate prognostic value of miRNA candidates with and without incorporation of clinical prognostic factors (age, Gleason score and time from androgen deprivation therapy to clinical progression). In the screening cohort, we obtained ~6.80 million mappable RNA reads per patient. Of those with normalized read counts ? 5, 43% were mapped to miRNAs for a total of 375 known and 57 novel miRNAs. Cox regression analysis identified an association of miR-1290, -1246, and -375 with overall survival (FDR<0.1). Of those, higher levels of miR-1290 and -375 were verified to be significantly associated with poor overall survival (p<0.004) in the follow-up cohort. The miR-1290/-375-based prediction model showed better performance with time-dependent area under the curve (AUC) =72% compared to clinical variable-based model with AUC=65%. Plasma exosomal miR-1290 and miR-375 are promising prognostic biomarkers for CRPC patients. Prospective validation is needed for further development of these candidate miRNAs.
