Project description:The role and miRNA expression profile of exosomes in hypertension remain largely unknown, therefore, next generation sequencing was used to define the miRNA expression profile of plasma exosomes in spontaneously hypertensive rats (SHRs), the most widely used animal model of human essential hypertension, and their controls, normotensive Wistar-Kyoto rats (WKYs). Results revealed that percentages of miRNA in the total small RNA isolated from WKYs and SHRs were not significantly different. Twenty-seven miRNAs were significantly differentially expressed (DE) between WKY and SHR exosomes, among which 23 were upregulated and 4 were downregulated in SHR exosomes compared with WKY exosomes. Gene Ontology analysis and Kyoto Encyclopedia of Genes and Genomes pathway analysis of top 10 DE miRNAs identified hypertension-specific target genes/signaling pathways. In conclusion, our findings indicate the selective packing of miRNA cargoes into exosomes under hypertensive status, while facilitating the development of potential targets for the diagnosis, prevention and treatment of hypertension.

Project description:Remote ischemic conditioning (RIC) is a safely therapeutic strategy for a variety of ischemic diseases, with efficiency comparable to the classic in-situ ischemic methods. Recent evidence has shown that RIC could alter the content of circulating exosomes. microRNAs involves in numerous functionally different biological and physiological processes. The aim of this study is to identify the differentially expressed exosomal microRNAs in rat plasma with RIC and to further explore the functions in ischemic heart diseases. Five RIC rats and 5 control rats were enrolled in this study. We used microarray analysis to identify miRNA expression in their plasma exosomes.

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. Our study depict the miRNAs expression profiles in plasma exosomes of NSV patients and suggest that several miRNAs in plasma exosomes may serve as biomarkers for NSV.

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 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.

Project description:Purpose: Analysis of exosomal miRNA in plasma of patients with metastatic and non-metastatic pancreatic cancer. To identify exosomes cargo specific miRNAs promoting cancer metastasis. Methods: We divide the plasma samples into five groups according to whether they have metastasis and undergo surgery.The five groups are Health(20),Metastasis Pre-operation and Post-operation (14),Non-metastasis Pre-operation and Post-operation(9).Then we collected the exosomes by ultracentrifugation and extracted the small RNA in each sample.Then, we analyzed the expression changes of miRNA by small RNA sequencing. Result: Different groups have different expression of small RNA. Compared with the non-metastatic group, the expression of miR-92a-3p , miR-148-3p and miR-25-3p increased in the metastatic group. Conclusion:Exosomal miRNA in pancreatic cancer patient derived plasma were analyze using Hiseq2500 sequencing technique. We identified that miR-92a-3p, miR-148-3p and miR-25-3p enriched in metastatic pancreatic cancer patient plasma derived exosomes.

Project description:Numerous studies have elucidated the neuroprotective effect of 6-gingerol in central nervous system diseases. However, the potential role and mechanism of 6-gingerol on early brain injury (EBI) after subarachnoid hemorrhage (SAH) remains poorly understood. Here, we report that 6-gingerol exerts a neuroprotective effect on SAH-induced EBI through the GBP2/PI3K/AKT pathway. A SAH rat model was established by injecting femoral artery blood into the cisterna magna. 6-gingerol or vehicle was injected intraperitoneally one hour post-SAH induction. We found that the neurological function score and brain edema of SAH rats were significantly improved after 6-gingerol treatment, as well as neuronal apoptosis was attenuated in SAH rats by Nissl staining assay and TUNEL assay. To further explore potential molecular mechanisms associated with 6-gingerol, RNA sequencing was implemented to investigate the differences in transcriptomes between SAH rats with and without 6-gingerol treatment; and found that the expression of guanylate-binding protein 2 (GBP2) evidently was suppressed with 6-gingerol treatment compared to vehicle group. In addition, dual immunofluorescence was also employed to investigate changes in neurons, astrocytes, and microglia after 6-gingerol treatment. The results showed that GBP2 was expressed in neurons but not astrocytes or microglia. Western blotting analysis results demonstrated that the PI3K/AKT pathway was activated in the SAH rats treated with 6-gingerol. Furthermore, recombinant GBP2 protein and LY294002 (PI3K inhibitor) treatment reversed the effects of 6-gingerol treatment in SAH rats. These results indicate that 6-gingerol suppressed the expression of GBP2 to activate the PI3K/AKT pathway, improve neurologic outcomes, reduce brain edema and neuronal apoptosis. In summary, our findings suggest that 6-gingerol could attenuate EBI post-SAH in rats, and 6-gingerol may serve as a novel candidate neuroprotective drug for SAH-induced EBI.
