Project description:To investigate the potential effect of grazing movement on miRNA circulation in cattle, here we profiled miRNA expression in centrifugally prepared exosomes from the plasma of both grazing and housed Japanese Shorthorn cattle. Microarray analysis of the c-miRNAs resulted in detection of a total of 231 bovine exosomal miRNAs in the plasma, with a constant expression level of let-7g across the duration and cattle groups. Expression of muscle-specific miRNAs such as miR-1, miR-133a, miR-206, miR-208a/b, and miR-499 were undetectable, suggesting the mildness of grazing movement as exercise. Changes in miRNA expression in plasma exosome of cattle was measured at during 0, 1, 2 and 4 months of grazing or housing. Plasma exosome samples prepared from three cattle for each treatment were collected and mixed within the treatment at each time for microarray analysis .

Project description:Background: Gallstone disease (GSD) is one of the most prevalent and costly digestive system diseases in the world and can lead to pancreatitis, severe biliary tract infection and malignant biliary tract tumors. Gallstones can induce biliary colic, and the pain radiates to the shoulder and back. Severe attacks cause nausea and vomiting, which seriously affect the patient's work and life. Exosomes are important extracellular vesicles, and exosomal microRNAs (miRNAs) can be used as biomarkers and therapeutic targets for a variety of diseases. To the best of our knowledge, exosomal miRNA has not been well evaluated as a biomarker of the progression of cholelithiasis or the onset of biliary colic. Methods: Plasma samples from 10 patients with biliary colic attack were collected for exosome extraction, identification and miRNA sequencing. The exosome miRNA sequencing data of 10 healthy people in the GEO database were used as controls for data analysis. Results: Comparison of the plasma exosomal miRNAs of patients with biliary colic to those of healthy controls showed that 35 exosomal miRNAs were upregulated and 9 miRNAs were downregulated. GO and KEGG analyses showed that differential miRNAs are involved in the inflammatory response. The analysis of the subject operation characteristic curve shows that the expression of plasma exosomal miR-1268a can better reflect the attack characteristics of biliary colic than other miRNAs. miR-146a-3p participates in body inflammation and lipid metabolism processes and can be used as a potential therapeutic target. Conclusion: Plasma exosomal miRNAs can be used as biomarkers during the onset of biliary colic and can also be used as potential molecular targets to inhibit inflammation and analgesia.

Project description:Introduction: microRNAs are promising candidate breast cancer biomarkers due to their cancer-specific expression profiles. However, efforts to develop circulating breast cancer biomarkers are challenged by the heterogeneity of microRNAs in the blood. To overcome this challenge, we aimed to develop a molecular profile of microRNAs specifically secreted from breast cancer cells. Our first step towards this direction relates to capturing and analyzing the contents of exosomes, which are small secretory vesicles that selectively encapsulate microRNAs indicative of their cell of origin. To our knowledge, circulating exosome microRNAs have not been well evaluated as biomarkers for breast cancer diagnosis or monitoring. Methods: Exosomes were collected from the conditioned media of human breast cancer cell lines, mouse plasma of patient-derived orthotopic xenograft models (PDX), and human plasma samples. Exosomes were verified by electron microscopy, nanoparticle tracking analysis, and western blot. Cellular and exosome microRNAs from breast cancer cell lines were profiled by next-generation small RNA sequencing. Plasma exosome microRNA expression was analyzed by qRT-PCR analysis. Results: Small RNA sequencing and qRT-PCR analysis showed that several microRNAs are selectively encapsulated or highly enriched in breast cancer exosomes. Importantly, the selectively enriched exosome microRNA, human miR-1246, was detected at significantly higher levels in exosomes isolated from PDX mouse plasma, indicating that tumor exosome microRNAs are released into the circulation and can serve as plasma biomarkers for breast cancer. This observation was extended to human plasma samples where miR-1246 and miR-21 were detected at significantly higher levels in the plasma exosomes of 16 breast cancer patients as compared to the plasma exosomes of healthy control subjects. Receiver Operating Characteristic (ROC) curve analysis indicated that the combination of plasma exosome miR-1246 and miR-21 levels is a better indicator of breast cancer than their individual levels. Conclusions: Our results demonstrate that certain microRNA species, such as miR-21 and miR-1246, are selectively enriched in human breast cancer exosomes and significantly elevated in the plasma of breast cancer patients. These findings indicate a potential new strategy to selectively analyze plasma breast cancer microRNAs indicative of the presence of breast cancer.
