Project description:Exposure to high-dose radiation causes life-threatening serious intestinal damage. Histological analysis is the most accurate method for judging the extent of intestinal damage after death. However, it is difficult to predict the extent of intestinal damage to body samples. Here we focused on extracellular microRNAs (miRNAs) released from cells and investigated miRNA species that increased or decreased in serum and feces using a radiation-induced intestinal injury mouse model. A peak of small RNA of 25–200 nucleotides was detected in mouse serum and feces 72 h after radiation exposure, and miRNA presence in serum and feces was inferred. MiRNAs expressed in the small intestine and were increased by more than 2.0-fold in serum or feces following a 10 Gy radiation exposure were detected by microarray analysis and were 4 in serum and 19 in feces. In this study, miR-375-3p, detected in serum and feces, was identified as the strongest candidate for a high-dose radiation biomarker in serum and/or feces using a radiation-induced intestinal injury model.
Project description:The dataset contains FASTQ files referring to the study "Small RNA sequencing from CSF extracellular vesicles - PD/CTR". For this project, RNA was isolated from CSF extracellular vesicles obtained by ultracentrifugation. Libraries were prepared with the TruSeq Small RNA library prep Illumina, and sequencing conducted in the Illumina HiSeq4000.
Project description:Fecal and amniotic fluid samples were collected from 25 pregnant women undergoing elective Caesarean section delivery after a term pregnancy at Oulu University Hospital, Oulu, Finland. Extracellular vesicles (EVs) were isolated from both sample types and their protein cargo analyzed using LC-ESI-MS/MS.
